Normalized effects of fenfluramine versus recording depth or CF. A. Normalized fenfluramine-evoked changes in spike count versus recording depth. Dashed line indicates zero change in spike count; negative values are spike count decreases and positive values are spike count increases. The relationship between spike count and recording depth is not statistically significant (linear regression, p = .943; r2 = 0). B. In the same neuron population, the relationship between spike count change and CF is also not significant (p = .476 r2 = .005).
