Figure 2.

P300 waveforms in response to olanzapine treatment (right). P300 waveforms were averaged for 16 subjects per group. Black lines represent P300 activity for control subjects. Blue lines show P300 for patients at baseline, whose amplitudes are diminished compared to control subjects. After 6 month treatment with olanzapine, P300 amplitudes were increased, as indicated by redlines. Scores of verbal memory and quality of life were also increased by olanzapine (inset). Bars represent mean + SE.
