Document Summary

There are several techniques: behavioural testing: using the divided visual field. Similar to handedness, language lateralization may have come about because the segregation of functions of the separate halves of the brain allows for simultaneous parallel processing. Thus, it represents a solution to the competition for space within the brain and to the problem of functional incompatibility. Asymmetry seems to be a prerequisite for optimal function rather than an epiphenomenon of evolution and critical for an organism"s adaptation to the environment. When we use pet tracers to map the brain, widespread activation of the occipital lobe is typically seen in tasks which involve visual stimulation. Occipital lobe receives signals from the retina and is believed to play a role in visual perception. We can use different visual stimuli to activate certain areas of the occipital lobe and map the activity.
