Extracellular calcium activity changes in cat sensorimotor cortex induced by iontophoretic application of aminoacids.

abstract：:Subjects exposed to a rotating environment that perturbs their postural sway show adaptive changes in their voluntary spatially directed postural motion to restore accurate movement paths but do not exhibit any obvious learning during passive stance. We have found, however, that a variable known to characterize the de...
