where are auditory signals processed in the brain?
temporal lobe
bullet::::- auditory: adjacent areas in the superior, posterior, and lateral parts of the temporal lobes are involved in high-level auditory processing. the temporal lobe is involved in primary auditory perception, such as hearing, and holds the primary auditory cortex. the primary auditory cortex receives sensory information from the ears and secondary areas process the information into meaningful units such as speech and words. the superior temporal gyrus includes an area (within the lateral fissure) where auditory signals from the cochlea first reach the cerebral cortex and are processed by the primary auditory cortex in the left temporal lobe.

on 31 january 2012 brian pasley and colleagues of university of california berkeley published their paper in plos biology wherein subjects' internal neural processing of auditory information was decoded and reconstructed as sound on computer by gathering and analyzing electrical signals directly from subjects' brains. the research team conducted their studies on the superior temporal gyrus, a region of the brain that is involved in higher order neural processing to make semantic sense from auditory information. the research team used a computer model to analyze various parts of the brain that might be involved in neural firing while processing auditory signals. using the computational model, scientists were able to identify the brain activity involved in processing auditory information when subjects were presented with recording of individual words. later, the computer model of auditory information processing was used to reconstruct some of the words back into sound based on the neural processing of the subjects. however the reconstructed sounds were not of good quality and could be recognized only when the audio wave patterns of the reconstructed sound were visually matched with the audio wave patterns of the original sound that was presented to the subjects. however this research marks a direction towards more precise identification of neural activity in cognition.
