Document Summary

The outer most layer of the brain, containing our higher order abilities such as thinking and language. We have a much better developed cerebral cortex when compared with animals, allowing us to have a broader, more unique range of skills and abilities. Psychosurgery (invasive) can be used in very severe mental illness cases when medics believe a specific area of the brain is contributing to the illness. A surgeon will lesion those specific regions of the brain. Deep brain stimulation (invasive) involves the insertion of electrodes into the brain to electrically stimulate those regions for therapeutic benefit, however this is only ever a last resort. When you need to see brain responses quickly and clearly: eeg and mri differ in spatial and temporal resolution. Define these concepts and note which technique is better in each. Temporal resolution refers to the precision of a measurement with respect to time. Pet involves the use of radioactive chemicals which are injected into intravenously.
