Aivopuolisko refers to the two hemispheres of the cerebrum, the largest part of the brain. These are the left hemisphere and the right hemisphere. They are separated by a deep groove called the longitudinal fissure and connected by a thick band of nerve fibers known as the corpus callosum. This structure allows for communication and coordination between the two sides.

While the hemispheres are structurally similar, they exhibit a degree of functional specialization, often referred to as brain lateralization. The left hemisphere is typically dominant for language processing, logic, and analytical thinking in most right-handed individuals. This includes understanding and producing speech, mathematical calculations, and sequential processing.

The right hemisphere is generally associated with spatial abilities, visual processing, facial recognition, and emotional understanding. It plays a significant role in creativity, intuition, and understanding context and tone. However, it is crucial to understand that this lateralization is not absolute. Both hemispheres work together continuously, and many complex tasks involve the coordinated effort of both sides. For instance, understanding emotions in speech requires both the auditory processing of the left hemisphere and the emotional interpretation of the right. Injuries to one hemisphere can affect functions typically associated with the other, highlighting the interconnectedness of brain activity.
