Corpus striatum

Striatum
Area of brain controlling movement, balance, and walking. Connects to and receives impulses from Substantia Nigra. Substantia Nigra
Black pigmented area of the midbrain where cells manufacture the neurotransmitter dopamine.

corpus striatum: A structure in the cerebral hemispheres consisting of two basal ganglia (the caudate and lentiform nuclei) and the fibers of the internal capsule that separate them.
[TABER ONLINE]

corpus striatum, striate body: one of the components of the basal nuclei; specifically, a subcortical mass of gray and white substance in front of and lateral to the thalamus in each cerebral hemisphere. The gray substance of this structure is arranged in two principal masses, the caudate nucleus and the lentiform nucleus; its name denotes the striate appearance on section of the area, produced by connecting bands of gray substance passing from one of these nuclei to the other through the anterior limb of the internal capsule.

That would be the complete phrase.

Good luck, Rouges

Dopaminergic and glutamatergic neurotransmissions in the **striatum** play an essential role in motor- and reward-related behaviors. Dysfunction of these neurotransmitter systems has been found in Parkinson's disease, schizophrenia, and drug addiction. Cyclin-dependent kinase 5 (CDK5) negatively regulates postsynaptic signaling of dopamine in the striatum. This kinase also reduces the behavioral effects of cocaine. Here we demonstrate that, in addition to a postsynaptic role, CDK5 negatively regulates dopamine release in the **striatum**. Inhibitors of CDK5 increase evoked dopamine release in a way that is additive to that of cocaine. This presynaptic action of CDK5 also regulates glutamatergic transmission. Indeed, inhibition of CDK5 increases the activity and phosphorylation of N-methyl-d-aspartate **receptors**, and these.....
