From Parallel Sequence Representations to Calligraphic Control: A Conspiracy of Neural Circuits [PDF]
, 2004 Calligraphic writing presents a rich set of challenges to the human movement control system. These challenges include: initial learning, and recall from memory, of prescribed stroke sequences; critical timing of stroke onsets and durations; fine control

Laterality Differences in Cerebellar–Motor Cortex Connectivity [PDF]
Cerebral Cortex, 2014 Lateralization of function is an important organizational feature of the motor system. Each effector is predominantly controlled by the contralateral cerebral cortex and the ipsilateral cerebellum. Transcranial magnetic stimulation studies have revealed hemispheric differences in the stimulation strength required to evoke a muscle response from the ...

Remembering Forward: Neural Correlates of Memory and Prediction in Human Motor Adaptation [PDF]
, 2012 We used functional MR imaging (FMRI), a robotic manipulandum and systems identification techniques to examine neural correlates of predictive compensation for spring-like loads during goal-directed wrist movements in neurologically-intact humans ...

Cerebellar premotor output neurons collateralize to innervate the cerebellar cortex [PDF]
Journal of Comparative Neurology, 2015 ABSTRACTMotor commands computed by the cerebellum are hypothesized to use corollary discharge, or copies of outgoing commands, to accelerate motor corrections. Identifying sources of corollary discharge, therefore, is critical for testing this hypothesis.

State Estimation in the Cerebellum [PDF]
, 2008 An exciting hypothesis about the cerebellum is that its role is one of state estimation—a process that combines afferent copies of motor commands with afferent sensory signals to produce a representation of the current status of the peripheral motor ...

Mechanisms of cognitive-behavioral therapy for obsessive-compulsive disorder involve robust and extensive increases in brain network connectivity. [PDF]
, 2017 Cognitive-behavioral therapy (CBT) is effective for obsessive compulsive disorder (OCD); however, little is understood about its mechanisms related to brain network connectivity.

Correlation between brain injury and dysphagia in adult patients with stroke
International Archives of Otorhinolaryngology, 2012 Introduction: In the literature, the incidence of oropharyngeal dysphagia in patients with cerebrovascular accident (AVE) ranges 20-90%. Some studies correlate the location of a stroke with dysphagia, while others do not.

Structural reorganization of the cerebral cortex after vestibulo-cerebellar stroke
NeuroImage: Clinical, 2021 Objective: Structural reorganization following cerebellar infarcts is not yet known. This study aimed to demonstrate structural volumetric changes over time in the cortical vestibular and multisensory areas (i.e., brain plasticity) after acute cerebellar

The cerebellum could solve the motor error problem through error increase prediction [PDF]
, 2015 We present a cerebellar architecture with two main characteristics. The first one is that complex spikes respond to increases in sensory errors. The second one is that cerebellar modules associate particular contexts where errors have increased in the ...
