Instead of just overriding satiety, this pathway commands a consummatory modeβ€”mice eat pellets, lick air, whatever’s availableβ€”suppressing food-seeking in favor of ingestion. We think this is likely mediated by inhibition in the supratrigeminal region and disinhibition of orofacial motor neurons.

First preprint from our lab: How might the brain override fullness signals to allow feeding after you’re full?

We set out to test how central amygdala inhibitory neurons gate satiation/satiety signals in the pons.

After 21 years at my dream job, I’m very sad to announce my early retirement from the National Institutes of Health. My life’s work has been to scientifically study how our food environment affects what we eat, and how what we eat affects our physiology.

Acute and circadian feedforward regulation of agouti-related peptide hunger neurons Douglass etΒ al. employ long-term, continuous fiber photometry to uncover new modes of agouti-related peptide (AgRP) neuron regulation in ad libitum, fasted, and circadian conditions. AgRP neuron activity exhibits a circadian rhythm, which controls daily feeding patterns through a neural circuit from the suprachiasmatic nucleus via the dorsomedial hypothalamus.

I’m excited to share my latest paper
@cp-cellmetabolism.bsky.social. HakanK and I recorded from AgRP neurons continuously for 1 month and found some exciting things during ad lib feeding, fasting and on circadian timescales www.cell.com/cell-metabol....
