Brain network functional connectivity changes in patients with anterior knee pain: a resting-state fMRI exploratory study.

Background: This study investigates the functional brain connectivity in patients with anterior knee pain (AKP). While biomechanical models are frequently employed to investigate AKP, it is important to recognize that pain can manifest even in the absence of structural abnormalities. Leveraging the capabilities of functional magnetic resonance imaging (fMRI), this research aims to investigate the brain mechanisms present in AKP patients.

Impaired recollection and initially preserved familiarity in a patient with bilateral fornix transection following third ventricle colloid cyst removal: A two-year follow-up study.

Objective: Recognition memory is widely accepted as a dual process-based model, namely familiarity and recollection. However, the location of their specific neurobiological substrates remains unclear. Similar to hippocampal damage, fornix damage has been associated with recollection memory but not familiarity memory deficits.

How Our Gaze Reacts to Another Person's Tears? Experimental Insights Into Eye Tracking Technology.

Crying is an ubiquitous human behavior through which an emotion is expressed on the face together with visible tears and constitutes a slippery riddle for researchers. To provide an answer to the question "How our gaze reacts to another person's tears?," we made use of eye tracking technology to study a series of visual stimuli. By presenting an illustrative example through an experimental setting specifically designed to study the "tearing effect," the present work aims to offer methodological insight on how to use eye-tracking technology to study non-verbal cues.

[Transcranial direct current stimulation and speech therapy intervention in people with aphasia: a systematic review of the literature].

Introduction: The recovery of aphasia may require adjuvant therapies to speech therapy rehabilitation. Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulatory technique that can be used to improve cortical brain activity.

Aim: To offer an overview of the tDCS in people with aphasia from a speech therapy point of view.

Contribution of executive functions to eating behaviours in obesity and eating disorders.

Background: Patients with eating disorders (ED) or obesity show difficulties in tasks assessing decision-making, set-shifting abilities and central coherence.

Aims: The aim of this study was to explore executive functions in eating and weight-related problems, ranging from restricting types of ED to obesity.

Method: Two hundred and eighty-eight female participants (75 with obesity; 149 with ED: 76 with restrictive eating, 73 with bingeing-purging symptoms; and 64 healthy controls) were administered the Wisconsin Card Sorting Test, the Iowa Gambling Task, and the Group Embedded Figures Test to assess set-shifting, decision-making and central coherence, respectively.

Effects of a single session of SMR neurofeedback training on anxiety and cortisol levels.

Objectives: According to some studies, a putatively calming effect of EEG neurofeedback training could be useful as a therapeutic tool in psychiatric practice. With the aim of elucidating this possibility, we tested the efficacy of a single session of ↑sensorimotor (SMR)/↓theta neurofeedback training for mood improvement in 32 healthy men, taking into account trainability, independence and interpretability of the results.

Methods: A pre-post design, with the following dependent variables, was applied: (i) psychometric measures of mood with regards to anxiety, depression, and anger (Profile of Mood State, POMS, and State Trait Anxiety Inventory, STAI); (ii) biological measures (salivary levels of cortisol); (iii) neurophysiological measures (EEG frequency band power analysis).

Funciones ejecutivas y regulación emocional en obesidad y trastornos alimentarios.

Introduction: eating disorders (ED) such as anorexia nervosa (AN) or bulimia nervosa (BN), as well as obesity (OB), are related to emotional and neuropsychological impairments on measures of cognitive flexibility, central coherence or decision making. However, little is known about the association among emotional regulation, neuropsychological variables and affect. Objectives: to analyze whether neuropsychological and affect variables can predict emotional regulation in ED and in OB.

[Lafora disease: a review of the literature].

Introduction: Lafora disease is autosomal recessive progressive myoclonus epilepsy with late childhood-to teenage-onset caused by loss-of-function mutations in either EPM2A or EPM2B genes encoding laforin or malin, respectively.

Development: The main symptoms of Lafora disease, which worsen progressively, are: myoclonus, occipital seizures, generalized tonic-clonic seizures, cognitive decline, neuropsychiatric syptoms and ataxia with a fatal outcome. Pathologically, Lafora disease is characterized by the presence of polyglucosans deposits (named Lafora bodies), in the brain, liver, muscle and sweat glands.

Psychobiological response to an anger induction task in schizophrenia: The key role of anxiety.

In this study an anger induction laboratory task was applied to men with schizophrenia, and resulted in significant changes in different psychophysiological parameters that were measured in a pre-post design. We observed a significantly greater self-reported anger mood and negative affection, lower self-reported positive affection, an increase in cardiovascular reactivity (with blood pressure in deeper affection compared to controls), higher salivary testosterone levels, lower salivary cortisol levels, and an increase in right ear items reported in dichotic listening. Furthermore, clinical risk factors related to anger in our patients were analyzed by Stepwise Regression analyses.

Differential effects of cognition-focused interventions for people with Alzheimer's disease: A meta-analysis.

Objective: The efficacy of cognition-focused interventions (CFIs) for the treatment of Alzheimer's disease (AD) has been questioned recently. To date, the specific effects of cognitive rehabilitation (CR), cognitive training (CT), and cognitive stimulation [CS] have not been analyzed due to inconsistencies in the use of the comparison groups. This work aims to analyze the differential effects of CFIs by removing the influence of the comparison group from the estimates of the effects.

[Moyamoya disease: clinical, neuroradiological, neuropsychological and genetic perspective].

Introduction: Moyamoya disease (MMD) is an occlusive cerebrovascular disease characterized by progressive stenosis or occlusion in the terminal portion of the bilateral internal carotid arteries, affecting both children and adults.

Aim: To conduct a review and update on MMD from a clinical, neuroradiological, neuropsychological and genetic perspective.

Development: In this pathology, which occurs with ischemia or cerebral hemorrhage, an unusual compensatory vascular network (moyamoya vessels) develops at the base of the brain in the form of collateral channels.

[Neuropsychology of Tourette's disorder: cognition, neuroimaging and creativity].

Introduction: Tourette's disorder is the result of fronto-striatal brain dysfunction affecting people of all ages, with a debut in early childhood and continuing into adolescence and adulthood.

Development: This article reviews the main cognitive, functional neuroimaging and creativity-related studies in a disorder characterized by an excess of dopamine in the brain.

Conclusions: Given the special cerebral configuration of these patients, neuropsychological alterations, especially in executive functions, should be expected.

Are cognitive interventions effective in Alzheimer's disease? A controlled meta-analysis of the effects of bias.

Unlabelled: [Correction Notice: An Erratum for this article was reported in Vol 30(5) of Neuropsychology (see record 2016-25217-001). In the article the first sentence of the third paragraph of the Source of bias subsection in the Statistical Analysis subsection of the Correlational Meta-Analysis section should read "For the control condition bias, three comparison groups were differentiated: (a) a structured cognitive intervention, (b) a placebo control condition, and (c) a pharma control condition without cognitive intervention or no treatment at all."]

Objective: There is limited evidence about the efficacy of cognitive interventions for Alzheimer's disease (AD).

Testing the Benefits of Neurofeedback on Selective Attention Measured Through Dichotic Listening.

The electrophysiological changes after a single session of neurofeedback training (↑SMR/↓Theta) and its effects on executive attention during a dichotic listening test with forced attentional procedures were measured in a sample of 20 healthy women. A pre-post moment test double blind design, with the inclusion of a group receiving sham neurofeedback, allowed for minimization of alien influences. The interaction of Moment × Group was significant, indicating an enhancement of SMR band after the real neurofeedback.

Deceit and facial expression in children: the enabling role of the "poker face" child and the dependent personality of the detector.

This study presents the relation between the facial expression of a group of children when they told a lie and the accuracy in detecting the lie by a sample of adults. To evaluate the intensity and type of emotional content of the children's faces, we applied an automated method capable of analyzing the facial information from the video recordings (FaceReader 5.0 software).

Neuropsychological impairments in anorexia nervosa: a spanish sample pilot study.

This work was aimed at obtaining a profile of neuropsychological impairments in young Spanish participants with anorexia nervosa (AN) to demonstrate that right-hemisphere and frontal capacity impairments are present not only in the acute phase but also after weight recovery in a Spanish sample compared with a healthy control group. Twelve patients with AN in the acute phase (body mass index [BMI] < 17) were compared both to 16 healthy control subjects and 12 weight-recovered AN participants (BMI ≥ 17) matched by age, IQ, and educational level by utilizing a wide neuropsychological battery. Differences were found between AN groups only for long-term verbal memory, which worsens as BMI increases.

The sad, the angry, and the asymmetrical brain: dichotic listening studies of negative affect and depression.

Dichotic Listening (DL) is a valuable tool to study emotional brain lateralization. Regarding the perception of sadness and anger through affective prosody, the main finding has been a left ear advantage (LEA) for the sad but contradictory data for the anger prosody. Regarding an induced mood in the laboratory, its consequences upon DL were a diminished right ear advantage (REA) for the induction of sadness and an increased REA for the induction of anger.

What happens when we get angry? Hormonal, cardiovascular and asymmetrical brain responses.

This study aimed to evaluate neuroendocrine and cardiovascular responses together with changes in brain asymmetry following an anger mood induction laboratory task. Previous research has shown an increase in heart rate and blood pressure when anger is experienced. Increased testosterone and decreased cortisol in response to anger and aggressive behavior have also been reported.

Corpus callosum function in verbal dichotic listening: inferences from a longitudinal follow-up of Relapsing-Remitting Multiple Sclerosis patients.

This study conducted a follow-up of 13 early-onset slightly disabled Relapsing-Remitting Multiple Sclerosis (RRMS) patients within an year, evaluating both CC area measurements in a midsagittal Magnetic Resonance (MR) image, and Dichotic Listening (DL) testing with stop consonant vowel (C-V) syllables. Patients showed a significant progressive loss of posterior CC areas (isthmus and splenium) related to increasing EDSS scores and an enhancing right ear advantage (REA) over time. A significant correlation between posterior CC areas and DL scores emerged in both evaluations, being negative for the right and positive for the left ear.

A comparison of the effects for sustained versus shifted attention on dichotic listening performance.

We measured the effect of two types of directed attention instructions, sustained by a verbal cue or shifted by a tone cue with different time intervals (150, 450, and 750 ms), on a consonant-vowel dichotic listening (C-V DL) test for a large group of right- and left-handed participants of both sexes. An increasing of the hits and a decreasing of the intrusions from the baseline DL test scores was evident for both types of attentional manipulations, with no differences regarding sex or handedness. Increasing the time from 150 to 450 ms benefited the focusing of attention but this advantage was markedly attenuated at the longer 750-ms interval.

Increased cortisol and decreased right ear advantage (REA) in dichotic listening following a negative mood induction.

This study aimed to evaluate neuroendocrine responses and changes in perceptual asymmetry following an induced negative affect. Cortisol increasing in response to negative affect has been reported, while current brain models of emotion processing link negative affect to the right hemisphere. In this study, the Velten Mood Induction Procedure was used to generate neutral or negative affect in 44 healthy subjects.

Spectroscopic axonal damage of the right locus coeruleus relates to selective attention impairment in early stage relapsing-remitting multiple sclerosis.

Lower levels of N-acetylaspartate (NAA), a marker of axonal damage, have been found in the normal-appearing white matter (NAWM) of relapsing-remitting multiple sclerosis (RRMS) patients with low physical disability. However, its relation to the clinical status of these patients remains unclear. We explored the association between NAA levels [normalized to creatine (Cr), NAA/Cr] and a cognitive feature that is not measured by the standard scales that address functional disability [e.

Salivary testosterone is related to both handedness and degree of linguistic lateralization in normal women.

The aim of this study was to test the hypothesis that individual differences in testosterone (T) are associated with different patterns of linguistic lateralization and hand preference. Twenty left-handed (LH) and 19 right-handed (RH) women filled in a handedness questionnaire and performed a consonant-vowel dichotic listening test (DL-CV). Salivary T was measured by radioimmunoassay (RIA).

Dichotic listening and corpus callosum magnetic resonance imaging in relapsing-remitting multiple sclerosis with emphasis on sex differences.

Twenty-five early-onset relapsing-remitting multiple sclerosis patients (12 women and 13 men) with mild disability were compared with 25 matched controls in a dichotic listening (DL) test under nonforced and forced attentional-shift conditions. Patients showed left ear impairment and no left ear advantage in the forced-left condition. Four corpus callosum (CC) regions were measured in patients on a midsaggital magnetic resonance imaging scan.

Test-retest performance for the consonant-vowel dichotic listening test with and without attentional manipulations.

The present work aimed to replicate Hugdahl and Hammar's (1997) study on the reliability of dichotic listening under divided or focused attention conditions. With the same consonant-vowel syllable dichotic listening procedure, 16 subjects were tested twice, 2 weeks apart. The design included a condition without attentional instructions (nonforced) and two conditions with the instruction to attend either to the right- or the left-ear input.
