Neural dynamics and brain function

Previous microelectrode recordings in the putamen of monkeys have revealed a class of tonically active neurons without apparent behavioral correlates. The present study shows that such neurons have responses to stimuli that trigger movement but that these responses disappear when motor responses to the stimuli are extinguished. The short latency of the responses (less than for other putamen neurons) suggests that they may play a role in linking conditioned stimuli and responses.
