What does the ventral pallidum do?
The ventral pallidum is a convergent point for limbic reward signals and an intermediate stage to diverse cognitive, affective and motor processes. It is a central site for coding and causing enhancements of reward learning, hedonics, and motivation (Figure 4).
What does substantia Innominata do?
It is included as part of the anterior perforated substance (as it appears to be perforated by many holes which are actually blood vessels). It is part of the basal forebrain structures and includes the nucleus basalis….

What is a globus pallidus infarct?
Most globus pallidus (GP) strokes are unilateral lacunar infarcts resulting from thromboembolic occlusion of a lenticulostriate artery; therefore, their margins reflect the vascular territory rather than the anatomic boundaries of the GP.
Where in the brain is the globus pallidus?
The globus pallidus is found below the cerebral cortex, adjacent to a structure called the putamen.
What does the NAcc do?
The nucleus accumbens (NAc) is a major component of the ventral striatum and is a key structure in mediating emotional and motivation processing, modulating reward and pleasure processing, and serving a key limbic-motor interface (Cohen et al., 2009; Salgado and Kaplitt, 2015).
What does the nucleus accumbens secrete?
Dopamine: Dopamine is released into the nucleus accumbens following exposure to rewarding stimuli, including recreational drugs like substituted amphetamines, cocaine, nicotine and morphine.
What is the olfactory tubercle?
The olfactory tubercle (OT), also known as the tuberculum olfactorium, is a multi-sensory processing center that is contained within the olfactory cortex and ventral striatum and plays a role in reward cognition.
