CBLL1 is hypomethylated and correlates with cortical thickness in transgender men before gender affirming hormone treatment.

Gender identity refers to the consciousness of being a man, a woman or other condition. Although it is generally congruent with the sex assigned at birth, for some people it is not. If the incongruity is distressing, it is defined as gender dysphoria (GD).

Neuropsychological deficits in patients with persistent COVID-19 symptoms: a systematic review and meta-analysis.

Long-term persistent symptoms of COVID-19 affect 30-80% of patients who have recovered from the disease and may continue for a long time after the disease has been overcome. The duration of these symptoms over time might have consequences that affect different aspects of health, such as cognitive abilities. The main objective of this systematic review and meta-analysis was to objectify the persistent COVID-19 cognitive deficits after acute phase of infection and to summarize the existing evidence.

Anatomical correlates of category-selective visual regions have distinctive signatures of connectivity in neonates.

The ventral visual stream is shaped during development by innate proto-organization within the visual system, such as the strong input from the fovea to the fusiform face area. In adults, category-selective regions have distinct signatures of connectivity to brain regions beyond the visual system, likely reflecting cross-modal and motoric associations. We tested if this long-range connectivity is part of the innate proto-organization, or if it develops with postnatal experience, by using diffusion-weighted imaging to characterize the connectivity of anatomical correlates of category-selective regions in neonates (N = 445), 1-9 month old infants (N = 11), and adults (N = 14).

Comparing transcranial direct current stimulation and transcranial random noise stimulation over left dorsolateral prefrontal cortex and left inferior frontal gyrus: Effects on divergent and convergent thinking.

The essential role of creativity has been highlighted in several human knowledge areas. Regarding the neural underpinnings of creativity, there is evidence about the role of left dorsolateral prefrontal cortex (DLPFC) and left inferior frontal gyrus (IFG) on divergent thinking (DT) and convergent thinking (CT). Transcranial stimulation studies suggest that the left DLPFC is associated with both DT and CT, whereas left IFG is more related to DT.

Effects of transcranial electrical stimulation techniques on foreign vocabulary learning.

Although the use of transcranial electrical stimulation (tES) techniques on healthy population has been linked to facilitating language learning, studies on their effects on foreign language learning processes are scarce and results remain unclear. The objective of this study was to analyze whether tES enhances foreign language learning processes. Sixty-four healthy native Spanish-speaking participants were randomly assigned to four groups (transcranial direct current, transcranial random noise, tDCS-tRNS stimulation, or sham).

Voice, Body Cues and Facial Expression in Emotion Recognition of Spanish Children and Adolescents: The Validation of Bell-Lysaker Emotion Recognition Test.

Emotion recognition has been traditionally measured trough the recognition of emotional expressions of static faces. Studies suggest that emotion recognition is progressively acquired from early stages in our infancy. However, the literature regarding other emotional domains such as voice or body movements is scarce.

The Effects of Testosterone on the Brain of Transgender Men.

Transgender men (TM) experience an incongruence between the female sex assigned when they were born and their self-perceived male identity. Some TM seek for a gender affirming hormone treatment (GAHT) to induce a somatic transition from female to male through continuous administration of testosterone. GAHT seems to be relatively safe.

Spanish adaptation and validation of the Social Attribution Task-Multiple choice (SAT-MC) versions I and II for children and adolescents.

Social cognition is progressively acquired from childhood to early adulthood. Nevertheless there is a shortage of social cognition scales with normative data for Spanish children and adolescents. Social Attribution Task-Multiple Choice (SAT-MC) and its alternate version SAT-MC-II are social cognition instruments that measure mentalization skills in adults with psychosis.

Effects of transcranial electrical stimulation techniques on second and foreign language learning enhancement in healthy adults: A systematic review and meta-analysis.

Background: Transcranial electrical stimulation (tES) techniques have been used to enhance different cognitive domains such as language in healthy adults. While several reviews and meta-analysis have been conducted on the effects of tES on different language skills (picture naming, verbal fluency, word reading), there has been little research conducted to date on the effects of tES on the processes involved in foreign language learning.

Objective: A meta-analysis was performed to quantify the effects of tES on foreign language learning processes (non-words, artificial grammar, and foreign languages), focusing on accuracy, response times and 1-week follow-up effects, if reported by the studies.

Long-Term Neurodevelopmental Outcomes after Moderate and Late Preterm Birth: A Systematic Review.

Objective: To systematically review and perform meta-analyses on the long-term neurodevelopmental outcomes of adults born moderate and late preterm (MLPT) in relation to cognitive functioning and psychiatric disorders.

Study Design: A search was conducted to identify any studies that involved prematurity in adulthood. From these studies, reports that included a group of MLPT adults and included description of cognitive and/or mental health domains (including specific long-term outcomes) were selected.

The Neuroanatomy of Transgender Identity: Mega-Analytic Findings From the ENIGMA Transgender Persons Working Group.

Background: In contrast to cisgender persons, transgender persons identify with a different gender than the one assigned at birth. Although research on the underlying neurobiology of transgender persons has been accumulating over the years, neuroimaging studies in this relatively rare population are often based on very small samples resulting in discrepant findings.

Aim: To examine the neurobiology of transgender persons in a large sample.

Reduced hippocampal subfield volumes and memory performance in preterm children with and without germinal matrix-intraventricular hemorrhage.

Preterm newborns with germinal matrix-intraventricular hemorrhage (GM-IVH) are at a higher risk of evidencing neurodevelopmental alterations. Present study aimed to explore the long-term effects that GM-IVH have on hippocampal subfields, and their correlates with memory. The sample consisted of 58 participants, including 36 preterm-born (16 with GM-IVH and 20 without neonatal brain injury), and 22 full-term children aged between 6 and 15 years old.

The effect of transcranial random noise stimulation (tRNS) over bilateral posterior parietal cortex on divergent and convergent thinking.

Creativity pervades many areas of everyday life and is considered highly relevant in several human living domains. Previous literature suggests that the posterior parietal cortex (PPC) is related to creativity. However, none of previous studies have compared the effect of transcranial random noise stimulation (tRNS) over bilateral PPC on both verbal and visual divergent thinking (DT) and Remote Associates Test (RAT) in the same experimental design.

A Neuropsychological Rehabilitation Program for Cognitive Impairment in Psychiatric and Neurological Conditions: A Review That Supports Its Efficacy.

Neuropsychological rehabilitation has been the focus of much scientific research over the past decades due to its efficacy in different pathologies. Advances in the neuropsychology field have led to improvements and changes in neuropsychological interventions, which in turn have given rise to different approaches and rehabilitation programs. REHACOP is an integrative neuropsychological rehabilitation program designed by specialist neuropsychologists.

Equivalent short forms of the Situational Feature Recognition Test 2: Psychometric properties and analysis of interform equivalence and test-retest reliability.

Objective: To obtain two equivalent short forms of the "Situational Feature Recognition Test, Version 2," a social perception test, and their psychometric properties.

Methods: Patients with schizophrenia (n = 101) were assessed at two different times. Statistical analyses were performed as follows: (1) Cronbach's alpha was used to assess reliability; (2) Spearman correlations, Wilcoxon signed-rank test, and a 2 (form) × 2 (time) repeated measures multivariate analysis of variance were used to analyse interform equivalence; (3) Sensitivity to change was studied by a 2 (group) × 2 (time) repeated measures multivariate analysis of variance; (4) Spearman correlations were employed to assess test-retest reliability, convergent and discriminant validity, and relationship with functionality and symptoms.

Improvement in creativity after transcranial random noise stimulation (tRNS) over the left dorsolateral prefrontal cortex.

Creativity has previously been shown to improve after the application of direct and alternating current transcranial stimulation over the dorsolateral prefrontal cortex (DLPFC). However, previous studies have not tested whether transcranial random noise stimulation (tRNS) was efficient for this purpose. The aim of this randomized, double-blind, placebo-controlled study was to investigate the effect of tRNS on both verbal convergent and (verbal and visual) divergent thinking during left DLPFC tRNS stimulation.

Altered frontal white matter asymmetry and its implications for cognition in schizophrenia: A tractography study.

Background: White matter (WM) alterations are well documented in schizophrenia. Abnormalities in interhemispheric fibers appear to account for altered WM asymmetry in the illness. However, the regional specificity (e.

Spanish adaptation and validation of the situational feature recognition test 2 (SFRT-2) in patients with schizophrenia and healthy controls.

The main purpose of the present study was to adapt and validate the social perception measure "Situational Feature Recognition Test 2″ (SFRT-2) in Spanish psychiatric and non-psychiatric population. One hundred and one patients with schizophrenia and 100 healthy controls (HC) were assessed. Test's reliability was studied by Cronbach's alpha coefficients.

Why does language not emerge until the second year?

From their second year, infants typically begin to show rapid acquisition of receptive and expressive language. Here, we ask why these language skills do not begin to develop earlier. One evolutionary hypothesis is that infants are born when many brains systems are immature and not yet functioning, including those critical to language, because human infants have large have a large head and their mother's pelvis size is limited, necessitating an early birth.

Auditory structural connectivity in preterm and healthy term infants during the first postnatal year.

Assessing language development in the first postnatal year is difficult, as receptive and expressive skills are rudimentary. Although outward manifestations of change are limited, the auditory language system is thought to undergo critical development at this age, as the foundations are laid for the rapid onset of spoken language in the second and third years. We recruited 11 infants, 7 healthy controls (gestational age = 40.

Using Functional Magnetic Resonance Imaging to Detect Preserved Function in a Preterm Infant with Brain Injury.

We studied developmental plasticity using functional magnetic resonance imaging (fMRI) in a preterm infant with brain injury on structural MRI. fMRI showed preserved brain function and subsequent neurodevelopment was within the normal range. Multimodal neuroimaging including fMRI can improve understanding of neural plasticity after preterm birth and brain injury.

White matter integrity in dyskinetic cerebral palsy: Relationship with intelligence quotient and executive function.

Background: Dyskinetic cerebral palsy (CP) is one of the most disabling motor types of CP and has been classically associated with injury to the basal ganglia and thalamus. Although cognitive dysfunction is common in CP, there is a paucity of published quantitative analyses investigating the relationship between white matter (WM) microstructure and cognition in this CP type.

Aims: This study aims (1) to compare brain WM microstructure between people with dyskinetic CP and healthy controls, (2) to identify brain regions where WM microstructure is related to intelligence and (3) to identify brain regions where WM microstructure is related to executive function in people with dyskinetic CP and (4) to identify brain regions where the correlations are different between controls and people with CP in IQ and executive functions.
