How many hemispheres does the brain cortex have?

The brain cortex is divided into two hemispheres, known as the left hemisphere and the right hemisphere. This division is crucial for various cognitive processes, with each hemisphere typically specializing in different functions. For example, language processing is primarily associated with the left hemisphere in most individuals, while spatial abilities and creative functions are often associated with the right hemisphere. This bilateral structure allows for complex processing and coordination of activities, as the hemispheres communicate through the corpus callosum, a bundle of neural fibers. Understanding the two-hemisphere model is fundamental in the study of neuroscience and psychology, particularly in exploring how different functions and behaviors may be localized in specific areas of the brain.
