This suggests that basal (i.e. non-singing) FoxP2 levels in area X are not regulated by
auditory input during song development.
In normal crickets, neurons that
receive auditory input from one cricket «ear» project up to the brain unilaterally, without crossing the cricket's «midline» (Figure 1A).
Visual and
auditory input pass through the thalamus, which regulates consciousness, before hitting the limbic system.
The primary auditory cortex, the part of the brain
where auditory input is processed, has been implicated in tinnitus - related distress.
Meanwhile cognitive scientist Gadi Geiger of the Massachusetts Institute of Technology found that people with dyslexia could attend to
multiple auditory inputs at once.
«It's as if the signals are compensating for the
lost auditory input, but they overcompensate and end up making everything noisy,» says Shore.
This discovery helps explain how humans can recover their perception of speech with electronic cochlear implants, which generate signals much simpler than
normal auditory inputs.
The process of receiving and decoding spoken words takes place in the auditory cortex, which is the part of the human brain's cerebral cortex that
processes auditory input.
Prominent researchers have questioned its value, claiming it relies too heavily
on auditory input and makes students passive recipients as opposed to active learners.
If they have
auditory input, and they have visual input.
Neurologists Daniel Winkowski and Eric Knudsen of Stanford University wired 12 owls with electrodes in the areas of their brains that process either visual or
auditory input.
«That suggests these regions are representing something more than just the visual and
auditory inputs that are coming in, but a kind of higher - level processing,» Baldassano says.
