Collective name for the caudate nucleus and putamen that together with the globus pallidus or pallidum form the striate body.

In addition, 24 images of the type III aspiny neurons from the human neostriatum [10], 15 neuronal images from the putamen (Figure 1(c)), and 9 neuronal images from the caudate nucleus (Figure 1(d)), were analyzed with the standard and the modified BC method.
The findings reveal a surprising extension of the neostriatum's role, as DiFeliceantonio notes that the brain region had primarily been linked to movement.
Previous research has mostly linked the dorsal neostriatum to movement.
Alterations in DA in the neostriatum found in the present study have also been reported previously.
In the early stages of learning, dopamine plays an essential role and the corresponding brain area in the loop is the neostriatum, which is the primary recipient of glutamatergic input from almost all the cortical regions and also the primary recipient of the major dopaminergic input from the mid-brain dopamine neurons involved in reward processing.
From there, the sensory input is relayed to a region, also within the neostriatum, called the higher vocal center, or HVC.

Joseph looks for age-related changes in brain cell function, focusing on an area of the brain that controls both motor and cognitive function--the neostriatum. As people and animals age, the cells become sluggish in responding to chemical stimulation, he says.
Parkinson's disease, which results in tremors and other movement disorders, causes people to lose brain cells that supply the chemical messenger dopamine to a strip of tissue called the neostriatum. Individuals with this condition find it difficult to track recurring events that, largely outside conscious awareness, shape their judgments, say psychologist Barbara J.
This includes a discussion of the patterns of cellular connectivity of different functional regions of the cerebral cortex, cerebellum and neostriatum and models for fast and slow neuronal circuits within the brain.
