The abundance of FFA1 in the brain and the high affinity for DHA suggest that FFA1 may play a role in neuronal function in the brain. It is hypothesized that DHA and arachidonic acid could improve memory function by interacting with FFA1 in the hippocampus neurons.[1] This hypothesis is based on the idea that once FFA1 is activated by these fatty acids, the resulting signal is related to progenitor cell proliferation.[13] This implies that FFA1 signaling could stimulate the production of new memory cells in the brain.
