Abstract

Multiple retrograde fluorescent tracing was employed to investigate the organization of the rat entopeduncular nucleus projections to the lateral habenula, ventral anterior-ventral lateral thalamus, parafasicular-centre median complex, and tegmenti pedunculopontis area of the brain stem. The results indicate that neurons in the rostral 2/3 of the entopeduncular nucleus project to the lateral habenula. In contrast, neurons in the caudal 1/3 of the entopeduncular nucleus project to the ventral anterior-ventral lateral thalamus, parafasicular-centre median complex, and tegmenti pedunculopontis area of the brain stem. The majority of neurons in the caudal 1/3 of the entopeduncular nucleus are retrogradely double-labeled from various combinations of tracer injections into the 3 termination areas to which they projected. Little or no retrograde labeling in the entopeduncular nucleus was produced by tracer injections in the substantia nigra or subthalamic nucleus. Only large injections of tracers in the tegmenti pedunculopontis are and the surrounding brain stem produced retrograde labeling in the entopeduncular nucleus. These brain stem injections also labeled a band of cells surrounding the entopeduncular nucleus in the zona incerta...Continue Reading

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.
