Definition: The antihemisphere, also known as the anticlockwise hemispheric axis or prefrontal pole, is the part of a brain that receives most of our visual input and regulates emotions. It's located in front of the orbit of the eye, right before the occipital lobe. Its function is crucial for understanding visual information, helping us perceive and interpret images. The antihemisphere divides into two hemispheres: one which receives sight information, called the parietal lobe; and another that focuses on auditory signals. This division also affects our ability to distinguish between different colors, understand speech sounds, and respond to various types of stimuli such as music or other visual stimuli. It's where emotions are processed most effectively.
