using DCM (14–16). Within auditory cortex, the mismatch response, measured with EEG, is best explained by an increase in postsynaptic sensitivity within each primary auditory region and increases in the influence of reciprocal connection (i.e., in both forward and backward connections) between the primary auditory region and ipsilateral STG (14).

May 04, 2020· In the primary auditory cortex the response to safe sounds was supressed during behaviour, while the spike rate to warning sounds was relatively unchanged. In contrast, in the secondary auditory areas and the frontal cortex, the response to the danger sound was enhanced while the response to safe sounds was unchanged.

Auditory cortex of bats and primates: managing species ...

This is supported by a reversal of the frequency gradients in primary auditory cortex between carnivores and primates (e.g., (27, 65)). If this theory is correct, anterior auditory areas in carnivores should be responsible for sound localization and posterior areas should primarily manage communication calls and other auditory objects.

Mar 30, 2018· The auditory pathway conveys the special sense of hearing.. Information travels from the receptors in the organ of Corti of the inner ear (cochlear hair cells) to the central nervous system, carried by the vestibulocochlear nerve (CN VIII).. This pathway ultimately reaches the primary auditory cortex for conscious perception.In addition, unconscious processing of auditory information occurs in ...

Primary auditory cortex - wikidoc

The primary auditory cortex is about the same as Brodmann areas 41 and 42. It lies in the posterior half of the superior temporal gyrus and also dives into the lateral sulcus as the transverse temporal gyri (also called Heschl's gyri). The primary auditory cortex is located in the temporal lobe.

Aura (symptom) - Wikipedia

Seizures. An epileptic aura is the consequence of the activation of functional cortex by abnormal neuronal discharge. In addition to being a warning sign for an impending seizure, the nature of an aura can give insight into the localization and lateralization of the seizure or migraine.. The most common auras include motor, somatosensory, visual, and auditory symptoms.
