Abstract

The amygdaloid complex was studied in the cat in Golgi-Kopsch stained section series. Golgi type I (or long axon) neurons are present in all the amygdaloid nuclei. They vary in the different nuclei in shape, arrangement and in size but all have axons that leave the amygdala to establish connections with other regions. They usually have one or more initial locally arborizing collaterals. Two types of interneurons with short axons (Golgi type II) can be distinguished especially in the basal, lateral, cortical nuclei and in the amygdaloid area. One type has an axon arborizing by repeated dichotomical ramifications or in a fountain-like manner, but it does not extend beyond the span of the dendritic tree. The other type has more the character of the neurogliform cells with extremely delicate, beaded processes, the axon and dendrites cannot be easily distinguished. A third type of interneurons was observed in the lateral and basal nuclei. This type of interneurons has a longer axon, which divides into two branches, one arborizes in the neighborhood of the cell body, the other passes on for a further distance to terminate in other nuclei of the complex. The classification of this cell type, hence, is a matter of argument. The intraam...Continue Reading

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.

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.
