“By temporarily preventing vision, we may be able to engage the adult brain to now change the circuit to better process sound,
The researchers found a change in the brain circuitry for the mice that experienced simulated blindness, specifically in the area of the brain that processes sound, called the primary auditory cortex. The primary auditory cortex allows conscious perception of pitch and loudness
The researchers concluded that a certain set of connectors in the primary sensory areas of the brain, called thalamocortical inputs, are less flexible in humans later in life. When another sense also impaired, however, those connectors can be reactivated to support the sense that is lagging.
