Single unit response of noradrenergic, serotonergic and dopaminergic neurons in freely moving cats to simple sensory stimuli.

abstract：:The lamprey brainstem contains a 'command system' which descends into the spinal cord to activate motor networks and initiate locomotion. In the present study, partial lesions were made in the rostral spinal cord in order to spare various tracts and determine which tracts carry the descending command signal to the spi...
