What does the ventral striatum control?

This area of the brain influences motivation, reward and more. Different areas of the brain do different things. The ventral striatum — located deep inside in the brain — plays roles in mood, addiction and learning.

Is the striatum a hippocampus?

The striatum and hippocampus, respectively, are parts of these systems, and are functionally linked via the prefrontal cortex (PFC).

Does the hippocampus project to the striatum?

Striatum is defined on the basis of its cortical connections, such that isocortex (neocortex) and allocortex (hippocampus and olfactory cortex) project to dorsal (caudate and putamen) and ventral striatum, respectively.

What structures are in the ventral striatum?

The ventral striatum consists of the nucleus accumbens and the olfactory tubercle. The dorsal striatum consists of the caudate nucleus and the putamen. A white matter, nerve tract (the internal capsule) in the dorsal striatum separates the caudate nucleus and the putamen.

What does the amygdala do?

The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.

What is the ventral striatum psychology?

The ventral striatum is a portion of the striatum. It consists of the nucleus accumbens and the olfactory tubercle. Some sources also include the ventromedial parts of the caudate nucleus and putamen. It is considered a reward center.

How is the amygdala important for memory?

There is extensive evidence that the amygdala is involved in affectively influenced memory. The central hypothesis guiding the research reviewed in this paper is that emotional arousal activates the amygdala and that such activation results in the modulation of memory storage occurring in other brain regions.

What is the role of the striatum in memory?

The dorsal striatum, hippocampus, and amygdala have been regarded as the central structures of distinct memory systems, in which the dorsal striatum mediates S-R/habit memory, the hippocampus mediates cognitive spatial memory, and the amygdala mediates stimulus-affect/emotional memories (Squire, 2004, White et al..

Is nucleus accumbens the same as ventral striatum?

The nucleus accumbens (NAc) is a major component of the ventral striatum and has long been thought to be a key structure involved in mediating motivational and emotional processes, the limbic-motor interface, and the effects of certain psychoactive drugs.
