Question

What is happening in the brain?

1. Outline where information is going once it leaves the organ of corti, and describe how it gets to auditory cortex

2. How is information organized in auditory cortex?

Answer 1

Data goes from the receptors in the organ of Corti of the internal ear (cochlear hair cells) to the focal sensory system, conveyed by the vestibulocochlear nerve (CN VIII). This pathway eventually comes to the primary auditory cortex for cognizant recognition. What's more, oblivious preparing of sound-related data happens in parallel. Secondary auditory cortex, which gets projections from the primary auditory cortex, lies along the predominant edge of the sidelong surface of the worldly flap in this way encompassing the primary cortex.

The auditory cortex partakes in the spectrotemporal, which means including time and recurrence, examination of the data sources passed on from the ear. Neurons in the auditory cortex are sorted out as indicated by the recurrence of sound to which they react best. Neurons at one finish of the auditory cortex react best to low frequencies; neurons at the other react best to high frequencies. There are numerous auditory regions, which can be recognized anatomically and on the premise that they contain a total frequency map. The motivation behind this frequency map is obscure, and is probably going to mirror the way that the cochlea is orchestrated by sound frequency. The auditory cortex is engaged with assignments, for example, recognizing and isolating auditory objects and distinguishing the area of a sound in space.
