Although it may seem like a simple process — baby cries, mom responds — one study in the Journal of Neuroendocrinology explains there is actually an incredible amount of
brain activity and
corresponding systems that work to produce a
response.
A previous study, published in 2013 in PLOS Biology by auditory neuroscientist Andrew King and his laboratory at the University of Oxford in England, showed that
brain cells can enhance the gain of their
responses, increasing the signal
corresponding to the sound of interest, while tuning out the noise.
