Local auditory-evoked activity is enhanced by NE treatment in NCM. Data are means ± SE; n = 22 cells. *P < 0.05, ***P < 0.001. A: auditory response strength (z score) is enhanced during NE treatment. Inset: individual trajectory plots show responses to BOS for each single unit. B: as demonstrated by firing rates before (baseline) and during the presentation of auditory stimuli (stimulus evoked), the NE-dependent enhancement of auditory responses is mediated by an increase in stimulus-evoked firing rates. Inset: individual trajectory plots show spikes/second at baseline and during stimulus presentation. C: local NE treatment in NCM also increases auditory signal-to-noise ratios. D: NE shows no effect on the rate of stimulus-specific adaptation in NCM.
