Image:Brain Activity

Description: Brain activity. Computer artwork showing activity (red) in the frontal (left) and temporal (centre) lobes of a human brain. The front of the brain is at left. The frontal lobe is associated with cognition, while the temporal lobe is associated with speech. The level of activity in the brain can be measured using electrodes placed on the scalp (electroencephalography, EEG). The greatest activity will be noticeable in areas of the brain associated with particular tasks when those tasks are being performed.
