Tonotopic organization in the cochlea forms throughout pre- and post-natal development through a series of changes that occur in response to auditory stimuli. [7] Research suggests that the pre-natal establishment of tonotopic organization is partially guided by synaptic reorganization; however, more recent studies have shown that the early changes and refinements occur at both the circuit and ...
The tonotopic layout of sound information begins in the cochlea where the basilar membrane vibrates at different positions along its length depending upon the frequency of the sound. Higher frequency sounds are at the base of the cochlea, if it were unrolled, and low frequency sounds are at the apex.
Place theory is a theory of hearing that states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane.By this theory, the pitch of a sound, such as a human voice or a musical tone, is determined by the places where the membrane vibrates, based on frequencies corresponding to the tonotopic organization of the primary auditory neurons.
A sociological theory is a supposition that intends to consider, analyze, and/or explain objects of social reality from a sociological perspective, [1]: 14 drawing connections between individual concepts in order to organize and substantiate sociological knowledge.
This attribute of the physiology of the basilar membrane can be illustrated in the form of a place–frequency map: [12] Simplified schematic of the basilar membrane, showing the change in characteristic frequency from base to apex. The basilar membrane supports the organ of Corti, which sits within the scala media. [4]
A sensory map is an area of the brain which responds to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation. In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina. In other cases it represents other stimulus properties ...
Social tuning is an intriguing social phenomenon that affects our personal beliefs and views both on a long-term and short-term basis. It impacts many important aspects of an individual's life, and can even play a role in determining a person's beliefs on a variety of important subjects.
There are multiple auditory areas (much like the multiple areas in the visual cortex), which can be distinguished anatomically and on the basis that they contain a complete "frequency map." The purpose of this frequency map (known as a tonotopic map ) likely reflects the fact that the cochlea is arranged according to sound frequency.
