Cellular coding of ingestion in the caudal brainstem

Truong Ly, Xinyang Yi, Grace Lee, James C. R. Grove, Youssef Sibih, Jun Yeop Oh, Longhui Qiu, Ho Namkung, Nilla Sivakumar, Zachary A. Knight

The paper investigates how food ingestion is encoded in the caudal nucleus of the solitary tract (cNTS) by comparing neural activity during gastric and oral food delivery in behaving animals.

Negative feedback control of hunger circuits by the taste of food

Tara J. Aitken, Truong Ly, Sarah Shehata, Nilla Sivakumar, Naymalis La Santa Medina, Lindsay A. Gray, Naz Dundar, Chris Barnes, Zachary A. Knight

This study shows that taste signals inhibit hunger-promoting AgRP neurons during eating, delaying satiety and increasing food intake when this inhibition is blocked.
