Fig. 6: Sensory perception.

The heat maps (Fig. 6a, b.) highlight the brain areas that were significantly different between control and PSI mice following exposure to the rewarding smell of benzaldehyde (almond) or the aversive fearful smell of TMT (fox). When processing reward (Fig. 6a.) the changes were predominantly positive BOLD (red) where controls were significantly greater than PSI mice. When processing fear (Fig. 6b.) the significant changes were all negative BOLD (blue) where controls were less than PSI than PSI mice.
