Increased activity in frontal motor cortex compensates impaired speech perception in older adults

Seniors have difficulties understanding speech in noisy environments and it is known that their brains compensate reduced sensory processing in auditory cortex by engaging prefrontal areas. Here the authors find that phoneme specificity and increased activity in speech motor regions provide a means...

Sumario:Seniors have difficulties understanding speech in noisy environments and it is known that their brains compensate reduced sensory processing in auditory cortex by engaging prefrontal areas. Here the authors find that phoneme specificity and increased activity in speech motor regions provide a means of compensation for decoding impoverished speech in older adults.
