Quotes About Striatum

The dorsomedial striatum, a subregion of the basal ganglia, seems to be critical to goal-directed behavior. If it is damaged, the rat's behavior will quickly become habitual even after limited exposure to a new task. Conversely, damage to the neighboring dorsolateral striatum will lead the rat to be more goal-directed and it will never lapse into habit, even after prolonged training.

Thus, as adolescence dawns, frontal cortical efficiency is diluted with extraneous synapses failing to make the grade, sluggish communication thanks to undermyelination, and a jumble of uncoordinated subregions working at cross-purposes; moreover, while the striatum is trying to help, a pinch hitter for the frontal cortex gets you only so far. Finally, the frontal cortex is being pickled in that ebb and flow of gonadal hormones. No wonder they act adolescent.

The striatum, and especially the caudate, can thus be thought of as a neuronal mosaic of reason and passion.
