A Model of Cerebellar Adaptation of Grip Forces During Lifting [PDF]

, 2003
We investigated adaptive neural control of precision grip forces during object lifting. A model is presented that adjusts reactive and anticipatory grip forces to a level just above that needed to stabilize lifted objects in the hand.

Purkinje cell models: past, present and future

Frontiers in Computational Neuroscience
The investigation of the dynamics of Purkinje cell (PC) activity is crucial to unravel the role of the cerebellum in motor control, learning and cognitive processes. Within the cerebellar cortex (CC), these neurons receive all the incoming sensory and motor information, transform it and generate the entire cerebellar output.

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.

Type-1 metabotropic glutamate receptor signaling in cerebellar Purkinje cells in health and disease [version 1; referees: 3 approved]

F1000Research, 2017
The cerebellum is a brain structure involved in coordination, control, and learning of movements, as well as certain aspects of cognitive function. Purkinje cells are the sole output neurons from the cerebellar cortex and therefore play crucial roles in ...

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

Movement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Processing of Visual Signals Related to Self-motion in the Cerebellum of Pigeons

Frontiers in Behavioral Neuroscience, 2013
In this paper I describe the key features of optic flow processing in pigeons. Optic flow is the visual motion that occurs across the entire retina as a result of self-motion and is processed by subcortical visual pathways that project to the cerebellum.

Changes in Purkinje cell firing and gene expression precede behavioral pathology in a mouse model of SCA2. [PDF]

, 2012
Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominantly inherited disorder, which is caused by a pathological expansion of a polyglutamine (polyQ) tract in the coding region of the ATXN2 gene.

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Regularity, variabilty and bi-stability in the activity of cerebellar Purkinje cells

Frontiers in Cellular Neuroscience, 2009
Recent studies have demonstrated that the membrane potential of Purkinje cells is bi-stable and that this phenomenon underlies bi-modal simple spike firing.

Generation and characterization of a mouse line for monitoring translation in dopaminergic neurons [PDF]

, 2017
We developed a mouse line targeting midbrain dopamine neurons for Translating Ribosome Affinity Purification(TRAP). Here, we briefly report on the basic characterization of this mouse line including confirmation of expression of the transgene in midbrain
