Visual Information and Sound Locations

Introduction For decades scientists have studied the integration of visual and auditory spatial information. Through this research, the scientific community gained knowledge about the benefits that the brain brings by combining visual information and spatial information. The advantage of the two methods that contribute to spatial positioning is that both audition and vision provide unique and complementary information to the brain.

The occipital lobe is behind the brain and is related to visual stimulation and interpretation of information. The primary visual cortex that receives and interprets information from the retina of the eye is located in the occipital lobes. Damage to this blade may cause visual problems such as difficulty in recognizing the object, unrecognizable colors, inability to recognize words, and so on. The midbrain is usually considered the smallest area in the brain. It acts as a relay for hearing and visual information. The midbrain controls many important functions such as visual system, auditory system, eye movement and so on. The core is called red nucleus and substantia nigra and is involved in the control of body movement. Black pigmentous nigra contains many neurons that produce dopamine. Degeneration of substantia nigra neurons is associated with Parkinson's disease

The type of information a neuron receives, processes, and transmits depends on its position in the nervous system. For example, neurons located in the occipital lobe process visual information while neurons in the movement path process and transmit information controlling muscle movement. However, regardless of the type of information, the basic anatomy of all neurons is the same. As mentioned above, myelin is a multilayered lipid and protein structure consisting of the plasma membrane of glial cells. In the peripheral nervous system (PNS), Schwann cells cause myelination. Cells can myelinate only a part of nerve cells. It does this by wrapping itself multiple times around the axon to form a multilayered sheath

Angle back allows you to link several kinds of language related information (auditory, visual, or sensation). It is close to other important brain regions such as parietal lobe to handle tactile sense, occipital lobe involved in visual analysis, and temporal lobe to process sound. With angle back you can associate perceived words with various images, emotions, and thoughts. Aphasia is used to describe the sequelae of a language that causes either or all problems of speaking, listening, reading, and writing. Some people with aphasia have difficulties in using words and sentences (expressive aphasia). Some people have problems in understanding other people (recipient aphasia). Other people with aphasia have experienced difficulty in using words and understanding (global aphasia). Aphasia can cause problems with speaking (speaking and understanding) and written language (reading and writing).
