Aplysia Pleural Ganglia 7 Days After Long-Term Sensitization Training.

Plueral ganglia were harvested immediately after the 5-day post tests for microarray analysis; these ganglia contain the VC nociceptors known to help encode sensitization memory. Samples from a left-trained and right-trained animal were combined to smooth out lateralized gene expression (32 animals produced 16 microarray samples, each having a set of trained plueral ganglia and a set of untrained plueral ganglia). In addition, within each batch of animals collected we matched the highest-forgetting left-trained animal with the highest-forgetting right-trained animal, and so on, producing samples consistent in levels of forgetting and considerable diversity in forgetting across samples.
