Abstract

The distribution and daily fluctuation of available glucocorticoid binding sites was studied in the brain of the quail Coturnix coturnix japonica, under physiological circumstances. A high level of triamcinolone acetonide binding was observed in some limbic structures (hippocampus and archistriatum), in the nucleus medialis and lateralis posterioris hypothalami and in the cerebellar cortex. The daily fluctuation of the available glucocorticoid binding sites in the preoptic area, hippocampus, archistriatum and cerebellar cortex can be described with a curve antiphased to the daily rhythm of plasma corticosterone concentration and seems to be synchronized by the plasma corticosterone level.

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.

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.
