Many response properties in primary auditory cortex (AI) are segregated spatially and organized topographically as those in primary visual cortex.

Participants were instructed to watch the bar during the relax period and actively attempt to lower it by decreasing primary auditory cortex activity during the lower phase.

«This allows us to search for what parts of the brain are generally activated by auditory stimuli,» he says, «and to separate an auditory field — for example [the] primary auditory cortex from higher auditory fields.»

When newborns perceived stimuli that contained manipulations of the acoustic structure (i.e., with regard to dissonance) and manipulation of the music - syntactic structure (i.e., with regard to the shift of tonal key), we observed rather symmetrical activity of the primary auditory cortices (Fig. 4).

The analysis revealed that by 26 weeks of gestation, the primary auditory cortex was in a much more advanced stage of development than the nonprimary auditory cortex.

Between 26 weeks and about 40 weeks — the latter the equivalent of full - term birth — the nonprimary auditory cortex in the preterm infants matured quickly, partially catching up to the primary auditory cortex.

The team focused on the primary auditory cortex, which is the first cortical region to receive auditory signals from the ears via other parts of the brain, and the nonprimary auditory cortex, which plays a more sophisticated role in processing those stimuli.

The results have shown that humans hear lower sounds — namely from 8 hertz on — which, after all, is a whole octave than had previously been assumed: an excitation of the primary auditory cortex could be detected down to this frequency.

The primary auditory cortex, the part of the brain where auditory input is processed, has been implicated in tinnitus - related distress.

By performing the exact same procedures with both groups using either real or sham neurofeedback, the researchers were able to distinguish the effect of real neurofeedback on control of the primary auditory cortex.

Brain cells in the primary auditory cortex can both turn down the noise and increase the gain on the signal.

In most people, sound waves enter the ear and are transmitted to the brain's primary auditory cortex.

By looking at activation of different brain regions while test subjects were exposed to different listening conditions, Dr. Johnsrude's research has revealed that the early processing of sound, which occurs in a brain region called the primary auditory cortex, depends on higher - level linguistic knowledge encoded in other regions of the brain.

They found that when a participant preferred the piece attributed to a professional player, there was significantly more activity in the primary auditory cortex, as well as a region of the brain associated with pleasure and reward.
