This procedure is usually done to treat severe epilepsy. As a result, the <strong>left and right hemispheres<\/strong> of the brain can no longer communicate directly with each other.<\/p>\n\n\n\n<p>Each hemisphere of the brain controls and processes sensory input and motor output for the <strong>opposite (contralateral) side<\/strong> of the body:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>left hemisphere<\/strong> controls and receives input from the <strong>right hand<\/strong>.<\/li>\n\n\n\n<li>The <strong>right hemisphere<\/strong> controls and receives input from the <strong>left hand<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Importantly, for most people, the <strong>left hemisphere houses the language centers<\/strong> (such as <strong>Broca\u2019s area<\/strong> and <strong>Wernicke\u2019s area<\/strong>), which are responsible for <strong>speech production and comprehension<\/strong>.<\/p>\n\n\n\n<p>So, when a split-brain patient <strong>holds an object in her left hand<\/strong>, that sensory information is processed by the <strong>right hemisphere<\/strong>. However, since the <strong>right hemisphere cannot communicate with the left hemisphere<\/strong> (which has the language centers), the patient <strong>cannot verbally name<\/strong> the object. She might be able to use her left hand to point to a matching picture or demonstrate the use of the object, but <strong>she will not be able to say the name<\/strong> of the object out loud.<\/p>\n\n\n\n<p>In contrast, if the object is placed in the <strong>right hand<\/strong>, the information goes to the <strong>left hemisphere<\/strong>, and the patient can <strong>easily verbalize<\/strong> the object\u2019s name.<\/p>\n\n\n\n<p>This phenomenon provides strong evidence for <strong>hemispheric specialization<\/strong>\u2014especially the role of the left hemisphere in language\u2014and helps us understand how brain lateralization affects behavior and cognition.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A split-brain patient can verbalize the name of the object that she is holding in her left hand.
