Outline of Final Research Achievements

Learning ability is essential for animals to better adapt and survive in variable environment, and such ability is implemented even in animals with simple neural circuit. Salt chemotaxis of the soil nematode Caenorhabditis elegans is a memory-dependent navigation behavior: animals are attracted to the salt concentration at which they have been fed, whereas they avoid it if they have been starved. We characterized the genes and neural mechanisms required for this learning.
Synaptic transmission from the taste receptor neuron ASER to a pair of interneurons AIB has been implicated as the site of modulation in salt chemotaxis learning. We here revealed that the sign of synaptic transmission reverses according to salt experience, which might generate migration toward opposite directions on the salt gradient. Both excitatory and inhibitory transmissions were at least partially glutamatergic and dependent on EAT-4 (VGLUT) that act in ASER and GLR-1 (AMPA receptor) in AIB.
