Abstract

Cytosol estrogen receptors (CER) were measured in ovariectomized hamsters, kept in a light:dark schedule of 14:10. Significant diurnal fluctuations in CER occurred in medial basal hypothalamus-preoptic area, but not in amygdala, anterior pituitary or uterus. Highest levels of CER in medial basal hypothalamus-preoptic area occurred 2 h before lights went out, and lowest levels 1 h after lights went out.

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.

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.

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.
