The central auditory pathway consists of a complex network of neurons and nuclei that connect the cochlea to the auditory cortex
The researchers recorded activity in the same regions of their brain, as well as in the auditory cortex
area responsible for interpreting sounds.
Music is processed in the auditory cortex
in this same region of the brain, which was why Charyton wanted to study the effect of music on the brains of people with epilepsy.
Objective: One of the most striking demonstrations of experience-dependent neuroplasticity comes from studies of deaf individuals in whom the temporal auditory cortex
changes its functional tuning to support visual or tactile functions.
Suppression is a physiologic process where sounds--in this case, patterned sounds--may likely be modulating the activity of the auditory cortex
and interrupting tinnitus generation.
The researchers said that when listen predicts what speaker is going to say, their brains take advantage of this by sending a signal to their auditory cortex
that it can expect sound patterns corresponding to predicted words.
When dogs heard canine vocalizations, regions in the front part of the primary auditory cortex
, a swath of neural tissue in the middle of the brain that helps detect sound, became active.
Emotional sounds, such as crying and laughter also had a similar pattern of activity, with an area near the primary auditory cortex
lighting up in dogs and humans.
The primary auditory cortex
is the region of the brain that is responsible for processing of auditory (sound) information.
And now the team have revealed the interaction between the region of the brain that processes sound, the auditory cortex
, and the amygdala, which is active in the processing of negative emotions when we hear unpleasant sounds.
He said: "It's a possible distress signal from the amygdala to the auditory cortex
The neural connections between the inner ear and primary auditory cortex
of the brain are intact in virtually all cases of disabling hearing impairment.
