area area of the brain responsible for a specific task. This involves activation or increase activation of many neurons in one area of the brain during a specific task. Ex. the inferior temporal cortex lights up in facial recognition.
distributed systems processing in the cortex
specific but dispersed regions of the brain concurrently activate during specific challenges.
language by distributed processing
language by modules
is responsible for speech, so damage to this area of the brain results in illogical langauge and an inability to understand others.
damage to the temporal lobe
there is a music region in the temporal lobe, damage to which has been seen to cause seizures and auditory hallucinations.
damage to the occipital lobe
the primary visual center, damage may cause cortical blindness, occasionally blind sight or an inability to recognize objects visually.
Frontal cortex and laughter
tumors and electrical stimulation of the frontal cortex have been shown to produce spontaneous laughter in affected patients.
What did we lear from the case study of Phineas Gage?
damage to the pre-frontal cortex result in a lack of respect for social conventions, sense of responsibility, initiative, focus, and future.
Egas Moniz recognize a calming effect of the removal of the pre-frontal lobe in chimpanzees and in 1935 began severing the links to and from the pre-frontal lobe.
Walter J. Freeman developed and began performing tranorbital lobotomies in 1937.
