title: Modification of transmission in the cuneate nucleus by raphe and periaqueductal gray stimulation.
abstract: In anesthetized decerebellate cats, with additional decerebration or decortication and with one of two types of cervical spinal cuts which either eliminated the dorsal half of the spinal cord or spared the dorsal funiculi, conditioning stimulation in the raphe nuclei or periaqueductal gray modified transmission in the cuneate nucleus. This was shown by 4 types of recordings: surface potentials, somatic afferent excitability testing, lemniscal tract response and extracellularly recorded single neuron activity.
