Effects of ATM on spike-field and EEG-field coherence during the first 30–90 min post-administration for the four frequency bands analyzed: delta (2–4 Hz), theta (4–8 Hz), alpha (8–12 Hz) and beta (12–18 Hz). a) ATM generally increased spike-field coherence at the high dose (1 mg/kg) across all frequency bands considered, with the exception of the delta frequency range. b) EEG-field coherence was affected by ATM across frequencies, with 1 mg/kg generally increasing coherence, whereas 0.3 mg/kg increased coherence only in the alpha and beta range. The low dose of ATM (0.1 mg/kg) decreased coherence across delta, theta and alpha frequency bands. (* = p < .05, compared to pre-drug condition).
