Serotonin mediates a learned increase in attraction to high concentrations of benzaldehyde in aged C. elegans.

Learning & memory (Cold Spring Harbor, N.Y.) - 1 Nov 2008

Tsui David, van der Kooy Derek

Abstract excerpt

We utilized olfactory-mediated chemotaxis in Caenorhabditis elegans to examine the effect of aging on information processing and animal behavior. Wild-type (N2) young adults (day 4) initially approach and eventually avoid a point source of benzaldehyde. Aged adult animals (day 7) showed a stronger initial approach and a delayed avoidance to benzaldehyde compared with young adults. This delayed avoidance is due to...
