Figure 7. TPN2 carries the CS signal, while TPN3 carries the US signal.
A and B. Aversive taste memory is impaired upon conditional silencing of TPN2 during either the pairing (A) or the testing/retrieval (B) phases, suggesting TPN2 carries the CS signal. (C) Conditional silencing of TPN3 during the pairing phase shows the inability to form a memory, suggesting TPN3 carries the US signal. (D) Conditional silencing of TPN3 during the testing phase has no impact on memory. Error bars are 95% CI; Fisher’s Exact Tests with Bonferroni adjusted alpha levels of *p<0.005 (0.05/10), **p<0.001 (0.01/10), ***p<0.0001 (0.001/10).
