Limbic system-associated membrane protein (LAMP) in primate amygdala and hippocampus

Hippocampus
P Y CôtéA Parent

Abstract

The distribution of the limbic system-associated membrane protein in the amygdaloid complex and hippocampal formation of cynomolgus monkeys (Macaca fascicularis) was studied with immunohistochemical procedures. A highly complex and heterogeneous staining pattern is encountered in the macaque amygdala. The basal, lateral, and accessory basal nuclei display the most intense immunostaining with local heterogeneities. The lateral division of the central nucleus also stains intensely, whereas the medial division of the central nucleus and the medial nucleus are more weakly stained. The dorsal division of the bed nucleus-amygdala continuum (extended amygdala) is strongly immunoreactive. The hippocampus displays the strongest immunoreactivity encountered so far in the primate brain. The intensity of the immunostaining is highest in the cornu Ammonis (Ammon's horn; CA1-CA3 fields) and gradually decreases toward the dentate gyrus or the subicular area. In the hippocampus proper, the stratum radiatum, the pyramidal layer, the stratum oriens, and the alveus all display intense immunoreactivity. The immunostaining is much less prominent in the dentate gyrus, whose granule cell layer is completely devoid of labeling. In the subicular area, ...Continue Reading

Cell Adhesion Molecules in the Brain

Cell adhesion molecules found on cell surface help cells bind with other cells or the extracellular matrix to maintain structure and function. Here is the latest research on their role in the brain.

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.
