Figure 5.

Relationship between the mismatch negativity (MMN) slope under placebo over frontal electrodes and the subscale impaired control and cognition, which includes disordered thought and loss of control over body and thought, induced by ketamine (solid line) and psilocybin (dotted line). Impaired control and cognition scores are expressed as the percentage of the maximum points possible. Notably, the MMN slope under placebo was predictive of ketamine-induced cognitive impairments (r=−0.67; P<0.05), but not of psilocybin-induced cognitive impairments (r=−0.11; P=NS).
