Influence of Age on Auditory Gating
This study utilized paired tones at 1000 Hz with a 500 ms interpair interval and a 10 s interstimulus interval to assess sensory gating. Forty-two participants, ranging from 3-72 years of age were used to observe maturational changes in amplitude, latency, and suppression ratios of the P50 waveform....
