Abstract

Every day we are bombarded by stimuli that must be assessed for their potential for harm or benefit. Once a stimulus is learned to predict harm, it can elicit fear responses. Such learning can last a lifetime but is not always beneficial for an organism. For an organism to thrive in its...read more

Limbic System

The limbic system is comprised of several different parts of the brain involved in emotion, motivation, learning, and memory. Discover the latest research on the limbic system here.

Post-Traumatic Stress Disorder

Post Traumatic Stress Disorder (PTSD) occurs after a person has been exposed to a traumatic event involving actual or threatened death. Discover the latest research on PTSD here.

Fear Conditioning

Fear Conditoning is often used in rodents to study emotional learning. Subjects express defensive responses to a neutral conditioned stimulus paired with an aversive unconditioned stimulus. Discover the latest research on Fear Conditioning 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.

Anxiety Disorders

Discover the latest research on anxiety disorders including agoraphobia, panic disorder, obsessive-compulsive disorder, and post-traumatic stress disorder here.

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.
