Tonotopy - Citizendia

Tonotopy (from Greek tono- and topos = place: the place of tones) is the spatial arrangement of where sound is perceived, transmitted, or received. It refers to the fact that tones close to each other in terms of frequency are represented in topologically neighbouring neurons in the brain. Tonotopic maps are a particular case of topographic organization. A topographic map is the ordered projection of a sensory surface like the retina or the skin or an effector system like the musculature to one or more structures of the Central

There is tonotopy in the cochlea, the small snail-like structure in the inner ear that sends information about sound to the brain. The cochlea is the auditory portion of the Inner ear. Its core component is the Organ of Corti, the sensory organ of hearing, which is distributed along

There is also tonotopy in the human auditory cortex, that part of the brain that receives and interprets sound information:

- sounds of low pitch project into the anterolateral aspect of Heschl's gyrus
- sounds of high pitch project deeply into the lateral fissure (which houses Heschl's gyrus). The cerebral cortex is a structure within the Brain that plays a key role in Memory, Attention, perceptual Awareness, Thought, The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain The transverse temporal gyri (also called Heschl's gyri or Heschl's convolutions) are found in the area of Primary auditory cortex in the Superior The transverse temporal gyri (also called Heschl's gyri or Heschl's convolutions) are found in the area of Primary auditory cortex in the Superior
