Your brain is divided into two halves (the cerebral hemispheres) connected by a band of nerve fibers called the corpus callosum.

00:00:11.000 --> 00:00:20.000
The two hemispheres of the cerebral cortex are almost identical in appearance, and they are symmetrical for basic sensory and motor functions.

00:00:20.000 --> 00:00:26.000
For a long time researchers assumed that they were also symmetrical for cognitive and behavioral functions. . .

00:00:26.000 --> 00:00:28.000
but that idea turned out to be wrong.

00:00:28.000 --> 00:00:36.000
Let us first examine some of the evidence for hemispheric specialization – the idea that each hemisphere has unique abilities.

00:00:36.000 --> 00:00:44.000
Later on we will demonstrate one aspect of hemisphere differences by reenacting a classic study involving word recognition.
