Teleworking for Medical Reasons: Evidence From a Spanish Multinational Company.

Objectives: The aim of the study is to describe the most common medical grounds for requesting or extending teleworking and to examine which requests are typically approved. This study also investigates whether there is a correlation with gender, age, or job location.

Methods: A prevalence study of 33,190 Spanish employees found that, last year, 106 teleworking requests were addressed exclusively for medical reasons.

Multi-centre analysis of networks and genes modulated by hypothalamic stimulation in patients with aggressive behaviours.

Deep brain stimulation targeting the posterior hypothalamus (pHyp-DBS) is being investigated as a treatment for refractory aggressive behavior, but its mechanisms of action remain elusive. We conducted an integrated imaging analysis of a large multi-centre dataset, incorporating volume of activated tissue modeling, probabilistic mapping, normative connectomics, and atlas-derived transcriptomics. Ninety-one percent of the patients responded positively to treatment, with a more striking improvement recorded in the pediatric population.

Beta band oscillations in the motor thalamus are modulated by visuomotor coordination in essential tremor patients.

Introduction: Beta oscillations in sensorimotor structures contribute to the planning, sequencing, and stopping of movements, functions that are typically associated with the role of the basal ganglia. The presence of beta oscillations (13-30 Hz) in the cerebellar zone of the thalamus (the ventral intermediate nucleus - Vim) indicates that this rhythm may also be involved in cerebellar functions such as motor learning and visuomotor adaptation.

Methods: To investigate the possible role of Vim beta oscillations in visuomotor coordination, we recorded local field potential (LFP) and multiunit activity from the Vim of essential tremor (ET) patients during neurosurgery for the implantation of deep brain stimulation (DBS) electrodes.

Top-down control of human motor thalamic neuronal activity during the auditory oddball task.

The neurophysiology of selective attention in visual and auditory systems has been studied in animal models but not with single unit recordings in human. Here, we recorded neuronal activity in the ventral intermediate nucleus as well as the ventral oral anterior, and posterior nuclei of the motor thalamus in 25 patients with parkinsonian (n = 6) and non-parkinsonian tremors (n = 19) prior to insertion of deep brain stimulation electrodes while they performed an auditory oddball task. In this task, patients were requested to attend and count the randomly occurring odd or "deviant" tones, ignore the frequent standard tones and report the number of deviant tones at trial completion.

Long-Term Follow-Up on Bilateral Posterior Hypothalamic Deep Brain Stimulation for Treating Refractory Aggressive Behavior in a Patient with Cri du Chat Syndrome: Analysis of Clinical Data, Intraoperative Microdialysis, and Imaging Connectomics.

Posterior hypothalamic-deep brain stimulation (pHyp-DBS) has been reported as a successful treatment for reducing refractory aggressive behaviors in patients with distinct primary diagnoses. Here, we report on a patient with cri du chat syndrome presenting severe self-injury and aggressive behaviors toward others, who was treated with pHyp-DBS. Positive results were observed at long-term follow-up in aggressive behavior and quality of life.

Single unit and beta oscillatory activities in subthalamic nucleus are modulated during visual choice preference.

Parkinson's disease is a neurodegenerative disease affecting the supply of dopamine to basal ganglia nuclei, leading to pathological beta band (13-35 Hz) oscillations in the subthalamic nucleus (STN). STN and beta activity are recognized in motoric functions but their role in cognitive functions remains elusive. We examined single unit and beta local field potential (LFP) activity in the STN during a visual choice preference task in PD patients (n = 12) undergoing deep brain stimulation surgery.

Beta oscillatory neurons in the motor thalamus of movement disorder and pain patients.

Excessive beta oscillations (15-25Hz) in the basal ganglia have been linked to the akineto-rigid symptoms of Parkinson's disease (PD) although it remains unclear whether the underlying mechanism is causative or associative. While a number of studies have reported beta activity in the subthalamic nucleus and globus pallidus internus, relatively little is known about the beta rhythm of the motor thalamus and its relation to movement disorders. To test whether thalamic beta oscillations are related to parkinsonian symptoms, we examined the spectral properties of neuronal activity in the ventral thalamic nuclei of five Parkinson's disease patients (two female, age range 50-72years) and compared them to five essential tremor (three female, aged 41-75) and four central pain patients (one female, aged 38-60).
