The lobes of the brain are the four major identifiable regions of the human cerebral cortex, and they comprise the surface of each hemisphere of the cerebrum.

Dopamine tends to limit and select sensory information arriving from the thalamus to the forebrain[citation needed].

A report from the National Institute of Mental Health says a gene variant that reduces dopamine activity in the prefrontal cortex is related to poorer performance and inefficient functioning of that brain region during working memory tasks, and to a slightly increased risk for schizophrenia.

The ventrolateral prefrontal cortex is important for the regulation of meaningful stimuli that a person experiences throughout their lifetime, such as images, letters, and names.

Damage to the prefrontal cortex can result in issues with one's long term and short-term memories, as well as create changes in people's behaviors and their abilities to plan and organize.

worsened after the usage of cannabis, suggesting that a TBI from childhood can enhance a development of psychosis due to the changes seen in the white matter within the frontal-temporal areas.

The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the postcentral gyrus,[6] and the dorsal stream of the visual system.

The major sensory inputs from the skin (touch, temperature, and pain receptors), relay through the thalamus to the parietal lobe.

There are many extrastriate regions, and these are specialized for different visual tasks, such as visuospatial processing, color differentiation, and motion perception.

[9] The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memories, language comprehension, and emotion association.

[10]: 21 Within the temporal lobe is an area of the brain called the hippocampus which is associated with forming new memories and learning new things.

The insular cortex has an important function for sending axons to the amygdala and responding to tones and somatosensory stimulation.

This finding supports that the insular cortex takes information to specific amygdala subdivisions creating different components for fear behaviors.

[13] The insulae are believed to be involved in consciousness and play a role in diverse functions usually linked to emotion or the regulation of the body's homeostasis.
