A build up of blood in a contained space (with limited excess space) like the skull will damage surrounding tissue. 79-91) may or may not (usually not) reversible: virtual (pp. 91-100) introducing artificial electrical stimulation preventing a part of the brain from functioning normally for a period of time. Virtual lesions are reversible and not considered dangerous. Refers to humans and specifically means studying the behavioural consequences of brain damage (in practice). 87-91: grouping by lesion location in the brain. All patients have lesion to same region of interest (roi: damage not exclusive to roi (non-roi damage differs from patient-to-patient) Roi often identified using functional neuroimaging: imaging alone prevents causal conclusions. Cerebellar damage: most obvious symptoms were motor deficits. It was concluded that cerebellum exclusively involved in motor control: pet/fmri: Cerebellum consistently active during cognitive tasks even when motoric requirements subtracted away: after pet/fmri: Use group-by-lesion method to look for cognitive symptoms of cerebellar damage.
