Direct retinal communication with the peri-amygdaloid area

Abstract

Retinal projections to the basal forebrain in male Syrian hamsters were examined at the ultrastructural level following bilateral intraocular injections of horseradish peroxidase conjugated to either cholera toxin (CT-HRP) or wheat germ agglutinin (WGA-HRP). Light level microscopic analysis confirmed retinal projections along basal telencephalon, and examination on the electron microscope of individual fibers from the peri-amygdaloid area revealed en passant synaptic profiles. Sections from animals treated with WGA-HRP showed evidence of transsynaptic communication in the form of labeled dendrites in the peri-amygdaloid area. Taken together, these data show that the retina communicates directly with the periamygdaloid area, where photic and chemosensory information may be integrated to modulate reproductive behavior.

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 Forebrain- Circuits

Basal forebrain is a region in the brain important for production of acetylcholine and is the major cholinergic output of the CNS. Discover the latest research on circuits in the basal forebrain here.

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.
