Webb13 apr. 2024 · Neural coding of auditory stimulus frequency is well-documented; however, the cortical signals and perceptual correlates of pitch have not yet been comprehensively investigated. This study examined the temporal patterns of event-related potentials (ERP) in response to single tones of pitch chroma, with an assumption that these patterns … WebbNote in Figure 63-3 that each time the peaks of the slow waves temporarily become more positive than −40 millivolts, spike potentials appear on these peaks. e higher the slow wave potential rises, the greater the frequency of the spike potentials, usually ranging between 1 and 10 spikes per second. e spike potentials last 10 to 40 times as ...
