Distributed Cerebellar Motor Learning: A Spike-Timing-Dependent Plasticity Model
Deep cerebellar nuclei neurons receive both inhibitory (GABAergic) synaptic currents from Purkinje cells (within the cerebellar cortex) and excitatory (glutamatergic) synaptic currents from mossy fibers. Those two deep cerebellar nucleus inputs are thought to be also adaptive, embedding interesting properties in the framework of accurate movements. We show that distributed spike-timing-dependen...
متن کاملAmphetamine enhances training-induced motor cortex plasticity.
OBJECTIVES Repetitive synchronized movements lead to short-term plastic changes in the primary motor cortex, which can be assessed by transcranial magnetic stimulation (TMS). Drugs which enhance such plastic changes could be of therapeutical interest, e.g. in patients with cerebral lesions. MATERIAL AND METHODS We studied the effect of amphetamine on motor performance and plastic changes in t...
متن کاملSomatosensory plasticity and motor learning.
Motor learning is dependent upon plasticity in motor areas of the brain, but does it occur in isolation, or does it also result in changes to sensory systems? We examined changes to somatosensory function that occur in conjunction with motor learning. We found that even after periods of training as brief as 10 min, sensed limb position was altered and the perceptual change persisted for 24 h. T...
متن کاملSkill-dependent Plasticity in Uninjured Motor Cortex
J Rehabil Med Suppl 41, 2003 DOI 10.1080/16501960310010070 It is now widely recognized that the cerebral cortex of adult human and non-human mammals is capable of widespread functional and structural plasticity. During the learning of new skills, cortical regions associated with sensorimotor function of the body parts most utilized for the skilled task come to be represented over larger cortica...
متن کاملUse-dependent and error-based learning of motor behaviors.
Human motor behavior is constantly adapted through the process of error-based learning. When the motor system encounters an error, its estimate about the body and environment will change, and the next movement will be immediately modified to counteract the underlying perturbation. Here, we show that a second mechanism, use-dependent learning, simultaneously changes movements to become more simi...
