Then, which brain region or pathway supports intracranial self stimulation?
Intracranial self-stimulation (ICSS) is an operant paradigm pairing lever presses with electrical stimulation of discrete brain pathways. Rats will lever press for stimulation of brain regions within the mesolimbic dopamine system, including the ventral tegmental area (VTA) and medial forebrain bundle (MFB).
Furthermore, what is the medial forebrain bundle? The medial forebrain bundle (MFB), is a neural pathway containing fibers from the basal olfactory regions, the periamygdaloid region and the septal nuclei, as well as fibers from brainstem regions, including the ventral tegmental area.
Similarly, you may ask, what is the reward center of the brain?
This area of the brain is primarily concerned with basic survival. Within the mesolimbic pathway is an area called the ventral tegmental area (VTA). The VTA projects to the nucleus accumbens (thought to be the reward center). The neurotransmitter most commonly linked with the mesolimbic system is dopamine.
What is reward deficiency syndrome?
Reward Deficiency Syndrome or RDS is brain disorder characterized by a clinically significant deficiency of the essential neurotransmitter--Dopamine in the brain's Reward Center, specifically the midbrain and prefrontal cortex. It is primarily acquired genetically but can also result from prolonged stress.
