[Changes in cellular activity in corpus Luysi after stimulation of monkey corpus striatum]

In a chronic experiment on three awake Macaca Cynomolgus, the activity of 27 neurons localized in the Corpus Luysi was recorded. Their spontaneous activity is continuous without rhythmicity or bursts. All neurons responded to a stimulation of the Striatum by an initial activation followed by an inhibition. These facts reveal the occurrence of a double projection from the Putamen and also from the head of the Caudate Nucleus to the Corpus Luysi.
