Most of them are located below the cerebral cortex and are known as subcortical.
The caudate nucleus is part of the telencephalon (forebrain), but is inside (underneath) of the cerebral cortex, so it is called a subcortical nucleus.
However, laboratory studies have not been able to unequivocally determine how the very basic information-processing "subcortical" regions of the brain function in processing risk and reward.
Research into "the brain chemistry of love" indicates that when a person sees a potential mate, it takes as little as a fifth of a second for the brain to launch a complex "love-related" chain reaction involving multiple areas of the cortical and more primitive subcortical portions of the brain.
Recording brain activity while these reappraisals took place revealed that highlighting the positive within the negative involves, once again, a tête-à-tête between the frontal cortex and subcortical regions processing emotional value.
Findings from a study I conducted a few years ago with prominent neuroscientist Elizabeth Phelps suggest that directing our thoughts of the future toward the positive is a result of our frontal cortex's communicating with subcortical regions deep in our brain.
When our attention is more distracted, the striatum, a subcortical part of the brain associated with rote activities, takes over.
Drum circles, Sacks says, are also therapeutic for people with dementia, because drumming “calls upon very fundamental, subcortical levels of the brain.”
The hypothalamus, in turn, is closely connected with the cortex and subcortical areas of the brain, so that physical and chemical changes within these areas produce corresponding physical effects within the hypothalamus, which in turn, by a series of physical processes whose complexity has only barely been suggested, produces such remote effects as the secretion of perspiration on the surface of the hands.
Reading, at the minimum involves the limbic system, occipital cortex, associational subcortical frontal lobe centers, and medial temporal lobe and should really be aligned to instructional practices that stimulate multiple brain areas.
