Researchers identify molecular link between gut bacteria and excitatory brain signaling in C. elegans

A new study published in Nature Cell Biology by Mark Alkema, Ph.D., professor of neurobiology at University of Massachusetts Chan Medical School, establishes an important molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
