Your stomach called – your striatum picked up! But does this actually happen in humans? Using simultaneous dopamine PET/fMRI, we show that the gut hormone #ghrelin helps the brain adjust motivation to current metabolic need. Here’s what we found👇 biorxiv.org/content/10.64898…

The first paper from the lab! In collaboration with @HyungJinChoi_ , we derived the need and motivation component from homeostatic RL, and showed that AgRP neurons and lateral hypothalamus LepR neurons encode need and motivation, respectively. science.org/doi/10.1126/scia…

A normative framework dissociates need and motivation in hypothalamic neurons

Experimental and computational methods elucidate the neural substrates of need and motivation in hypothalamic neurons.
