Document Summary

Sometimes people who suffer a stroke, especially in the right hemisphere, have difficulty recognizing faces. Many species use physical and behavioral signals to engage in communication, but we humans may be alone in our use of language. Verbal abilities are especially associated with the left hemisphere, while the right hemisphere plays a special role in spatial cognition: spatial cognition: the ability to navigate and to understand the spatial relationship between objects. The two cerebral hemispheres engage in lateralization.

Cerebral lateralization of function is masked by the rich neural connections between the hemispheres: they communicate with each other so quickly and so thoroughly that they seem to act as one. Some people experience frequent seizures that start in one hemisphere and then spread through the corpus callosum to involve the whole brain: corpus callosum: the main band of axons that connects the two cerebral hemispheres.
