Distinct High‐Gamma Signals in Primate Prefrontal Cortex Differentiate Cue Information, Preference Revision, and Expected Reward During Value‐Based Decisions [PDF]

European Journal of Neuroscience, Volume 64, Issue 3, August 2026.
High‐gamma activity in primate prefrontal cortex differentiates multiple task‐defined variables during sequential decision‐making, reflecting population‐level dynamics consistent with mixed‐selectivity representations. ABSTRACT Understanding how prefrontal cortex (PFC) signals evolve over time to support decision‐making requires characterizing both the

Involvement of Perimovement Neural Beta‐Oscillations in Strategic Aiming for Motor Adaptation [PDF]

European Journal of Neuroscience, Volume 62, Issue 6, September 2025.
ABSTRACT Humans rely on cognitive strategies to adapt upcoming movement in response to past movement error, for example, by strategic reaiming. We show that strategy‐based motor adaptation engages premovement and postmovement neural oscillations in the beta frequency band.

Superficial Ventral Premotor Pathways to Primary Motor Cortex Shape the Temporal Coordination of Precision Grasping [PDF]

European Journal of Neuroscience, Volume 64, Issue 1, July 2026.
Goal‐directed reaching–grasping actions rely on PMv–M1 connectivity. Participants performed precision or power grips toward small or large objects before and after the PMv–M1 cc‐PASAP protocol. The PMv‐M1 plasticity induction produced selective changes in temporal joint‐angle synergies during precision grip, with no effect on spatial synergies ...

Post‐stroke fatigue – a multidimensional problem or a cluster of disorders? A case for phenotyping post‐stroke fatigue [PDF]

The Journal of Physiology, Volume 603, Issue 3, Page 759-772, 1 February 2025.
Abstract figure legend This diagram summarises the many dimensions of fatigue, its behavioural presentation, the multiple models that have attempted to explain fatigue, the winning model of sensory attenuation model, which provides a basis for identifying phenotypes of fatigue along with the need for tailoring treatment to the presenting symptom ...

Enhanced Primary Motor Cortex Astrocyte Calcium Signaling With Motor Learning [PDF]

Neural Plasticity, Volume 2025, Issue 1, 2025.
Astrocytes form an integral part of the nervous system and are proposed to modulate neuronal circuits and behavior. The motor cortex plays a key role in the planning and execution of voluntary movements and makes key contributions to motor skill learning.

Premovement neuronal activity in the primary motor cortex is associated with the initiation of ipsilateral hand movements in monkeys

Neuroscience Research
The primary motor cortex (M1) is believed to be a cortical center for the execution of limb movements. Although M1 neurons mainly project to the spinal cord on the contralateral side, some M1 neurons project to the ipsilateral side via the uncrossed corticospinal pathway.

Attenuation of High Gamma Activity by Repetitive Motor Tasks [PDF]

Human Brain Mapping, Volume 46, Issue 2, February 1, 2025.
Repetitive grasping tasks attenuated high gamma activity of significant electrodes in the sensorimotor area over time. Repetition of grasping within each paradigm tended to be more influenced than the number of blocks, and spatial distribution of attenuated high gamma activity showed no significant association with the anatomical hand motor area ...

Seizures and electrophysiological features in familial cortical myoclonic tremor with epilepsy 1 [PDF]

Annals of Clinical and Translational Neurology, Volume 11, Issue 2, Page 414-423, February 2024.
Abstract Objectives To investigate and characterize epileptic seizures and electrophysiological features of familial cortical myoclonic tremor with epilepsy (FCMTE) type 1 patients in a large Chinese cohort. Methods We systematically evaluated 125 FCMTEtype 1 patients carrying the pentanucleotide (TTTCA) repeat expansion in the SAMD12 gene in China ...

Anticipatory countering of motor challenges by premovement activation of orexin neurons

PNAS Nexus, 2022
Abstract Countering upcoming challenges with anticipatory movements is a fundamental function of the brain, whose neural implementations remain poorly defined. Recently, premovement neural activation was found outside canonical premotor areas, in the hypothalamic hypocretin/orexin neurons (HONs).

Transcriptional substrates underlying functional connectivity profiles of subregions within the human sensorimotor cortex

Human Brain Mapping, Volume 43, Issue 18, Page 5562-5578, December 15, 2022., 2022
Our data represent the first report to date investigating the molecular mechanisms underlying rsFC of the sensorimotor cortex at the subregional level. Based on our results, the sensorimotor cortex can be conceptualized as the polygenic‐ and oligogenic‐modulated subregions, whose rsFC were related to gene sets diverging on their numbers and functional ...
