We review recent work on the role of intrinsic amygdala networks in the regulation of
classically conditioned defensive behaviors, commonly known as conditioned fear. These …

The last 10 years have witnessed a surge of interest for the mechanisms underlying the
acquisition and extinction of classically conditioned fear responses. In part, this results from …

Anatomy and Physiology. Physiol Rev 83: 803–834, 2003; 10.1152/physrev. 00002.2003 …

The hippocampus and the amygdala are essential components of the neural circuitry
mediating stress responses. The hippocampus, which provides negative feedback …

There are many advantages to defining emotions as states elicited by reinforcers, with the
states having a set of different functions. This approach leads towards an understanding of …

The amygdaloid nuclear complex is critical for producing appropriate emotional and
behavioral responses to biologically relevant sensory stimuli. It constitutes an essential link …

Although the amygdala complex is a brain area critical for human behavior, knowledge of its
subspecialization is primarily derived from experiments in animals. We here employed …

By means of quantitative analysis of the tissue components in the cortex of the mouse, this
book presents an overall picture of the cortical network which is then related to various …

After a few pairings of a threatening stimulus with a formerly neutral cue, animals and
humans will experience a state of conditioned fear when only the cue is present …

Fear conditioning and fear extinction are Pavlovian conditioning paradigms extensively
used to study the mechanisms that underlie learning and memory formation. The neural …
