This study aims to establish an imitation task of multi-finger haptics in the context of regular grasping and regrasping processes during activities of daily living. A video guided the 26 healthy, right-handed volunteers through the three phases of the task: (1) fixation of a hand holding a cuboid, (2) observation of the sensori-motor manipulation, (3) imitation of that motor action. fMRI recorded the task; graph analysis of the acquisitions revealed the associated functional cerebral connectivity patterns.

A 49-year-old female presented with the primary complaint of hand tremors. Neurological examination on admission revealed signs of cognitive impairment, bulbar palsy, dystonia, cerebellar ataxia, and pyramidal tract disease. T-weighted brain MRI revealed hyperintense signals in the subcortical white matter, basal ganglia, and cerebellar dentate nucleus, with no atrophy of the brainstem or corpus callosum.

Motor actions adapt dynamically to external changes through the brain's ability to predict sensory outcomes and adjust for discrepancies between anticipated and actual sensory inputs. In this study, we investigated how changes in target speed (v) and direction influenced visuomotor responses, focusing on gaze and manual joystick control during an interception task. Participants tracked a moving target with sinusoidal variations in v and directional changes, generating sensory prediction errors and requiring real-time adjustments.

Background: Direct cortical electrical stimulation remains the gold standard for delineation of the primary motor cortex in patients with drug-resistant epilepsy (DRE) undergoing epilepsy surgery evaluation OBJECTIVE: This study aimed to explore the efficacy and safety of functional motor mapping through Stereo-EEG (SEEG) electrode contacts in children with DRE at our institute.
Methods: We performed a retrospective analysis of children who underwent SEEG evaluation and functional cortical mapping via bipolar electrical stimulation at our institution between July 2020 and June 2024. Detailed clinical, radiological and neurophysiological variable were extracted; qualitative and quantitative variables were summarized using appropriate descriptive statistics.

Cell fate decisions during cortical development sculpt the identity of long-range connections that subserve complex behaviors. These decisions are largely dictated by mutually exclusive transcription factors, including CTIP2/Bcl11b for subcerebral projection neurons and BRN1/Pou3f3 for intra-telencephalic projection neurons. We have recently reported that the balance of cortical CTIP2-expressing neurons is altered in a mouse model of DDX3X syndrome, a female-biased neurodevelopmental disorder associated with intellectual disability, autism spectrum disorder, and significant motor challenges.
