Does the precommissural fornix excite neurons in the cat dorsal septum which project to the medial preoptic region?

abstract：:Little is known about mechanisms used by the nervous system to encode time. In light of recent evidence, cerebellar cortex involvement in the learned timing of conditioned eyelid responses shows promise as an area of investigation into neural timing mechanisms. Lesion studies indicate that the cerebellar cortex is nec...
