Reversal of object recognition memory deficit in perirhinal cortex-lesioned rats and primates and in rodent models of aging and alzheimer’s diseases.

Neuroscience 448:287-298. doi: 10.1016/j.neuroscience.2020.08.039

Objective: To determine if Object Recognition Memory (ORM) can be restored.

Summary: Memory-deficient rats were generated by induction of lesions to the perirhinal cortex (PRh) through an injection of OX7-SAP. Expression of regulator of G-protein signaling 14 of 414 amino acids (RGS14414) restored ORM in memory-deficient PRh-lesioned rats and nonhuman primates. This treatment was sufficient for full recovery of ORM in rodent models of aging and Alzheimer’s disease.

Usage: Rats were injected with OX7-SAP (0.9 mg in 1ml) in the PRh of the brain.
