Dopaminergic Modulation of Short-Term Associative Memory in Caenorhabditis elegans. [PDF]
J NeurochemForgetting is a vital, active process that clears irrelevant memories and supports new learning. Using the model organism Caenorhabditis elegans, we investigated how dopamine, a key neurotransmitter, regulates forgetting. Through behavioural assays and genetic manipulation of dopamine synthesis and signalling pathways, we found that dopamine‐deficient ...
