Transient and prolonged facilitation of tone-evoked responses induced by basal forebrain stimulations in the rat auditory cortex.

abstract：:Previous studies have reported abnormalities in fine hand and finger movements following interruption of the fasciculus cuneatus (FC) in primates. We report here that many of these deficits could be caused by an inability to actively regulate the position of the finger. Three macaques were trained to maintain the inde...
