FP activity in barrel cortex evoked by High and Low stimuli during different behavioral states. A, FFT power spectrums taken from spontaneous FP activity in barrel cortex, excluding periods of sensory stimulation, during active exploration, awake immobility and slow-wave sleep. B, C, Peak amplitude (B) and time to peak (C) of FP responses evoked in barrel cortex by 10 Hz trains of High and Low stimuli during either active exploration (left) or awake immobility (right). Statistically significant (p < 0.05) differences between the groups within a behavioral state are marked by brackets, and significant differences between the two behavioral states are marked with asterisks in the right columns. The first (s1) and the last (s10) responses in the 10 Hz train (10 stimuli) are measured.
