Inducing homeostatic-like plasticity in human motor cortex through converging
24 Transcranial stimulation techniques have revealed homeostatic-like metaplasticity in the hand 25 area of the human primary motor cortex (M1HAND) that controls stimulation induced changes in 26 corticospinal excitability. Here we combined two interventional protocols which induce long27 term depression (LTD)-like or long-term potentiation (LTP)-like plasticity in left M1HAND 28 through differ...
متن کاملPlasticity and primary motor cortex.
One fundamental function of primary motor cortex (MI) is to control voluntary movements. Recent evidence suggests that this role emerges from distributed networks rather than discrete representations and that in adult mammals these networks are capable of modification. Neuronal recordings and activation patterns revealed with neuroimaging methods have shown considerable plasticity of MI represe...
متن کاملSpine plasticity in the motor cortex.
Dendritic spines are the postsynaptic sites of the majority of excitatory synapses in the mammalian central nervous system. The morphology and dynamics of dendritic spines change throughout the lifespan of animals, in response to novel experiences and neuropathologies. New spines form rapidly as animals learn new tasks or experience novel sensory stimulations. This is followed by a selective el...
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 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...
