CEREBRART - Hallucination

Hallucinations are well-known examples of informational chaos in the brain - perceptions that occur in the absence of external stimuli produced by the spontaneous activity of nerve cells in the visual or auditory cortex and thought to be due to the chaotic nature of the autoactivation process and to the failure to recognize them as unreal - to distinguish inner and outer. People who have auditory hallucinations hear sounds and voices that seem to come from outside their heads and cannot recognize that the sounds are actually coming from within.

This CEREBRART work shows two activated brain areas that runs the neurocognitive system into chaotic hallucinatory iteration. Broca’s area (areas 44 and 45) is a region of the inferior frontal lobe with functions linked to speech production. And the auditory cortex of the superior temporal gyrus, the brain area that helps people hear sounds. Continuous feedback information flow between frontal lobe and auditory areas of the temporal lobe are extremely important for volitional speech production. Conversely, impairment of this feedback information flow, as shown here artistically, might be related to hallucinatory phenomena - people hear sounds produced by their own brains.
