A dual-pathway architecture enables chronic stress to disrupt agency and promote habit formation

Jacqueline R. Giovanniello, Natalie Paredes, Anna J. Wiener, Kathia Ramírez-Armenta, Chukwuebuka Oragwam, Hanniel O. Uwadia, Abigail L. Yu, Kayla Y. Lim, Jenna S. Pimenta, Gabriela E. Vilchez, Gift Nnamdi, Alicia Wang, Megha Sehgal, Fernando MCV Reis, Ana C. Sias, , Kate M. Wassum

This study identifies a dual amygdala-striatal pathway architecture by which chronic stress disrupts agency and promotes habit formation in mice.

A genetically-defined population in the lateral and ventrolateral periaqueductal gray selectively promotes flight to safety

Mimi Q La-Vu, Ekayana Sethi, Sandra Maesta‐Pereira, Peter J. Schuette, Brooke C Tobias, Fernando MCV Reis, Weisheng Wang, Saskia J. Leonard, Lilly Lin, Avishek Adhikari

The paper identifies a genetically-defined population of cck-expressing cells in the lateral and ventrolateral PAG that selectively promote flight to safety, revealing a molecular axis of functional organization in the PAG.

Dorsal premammillary projection to periaqueductal gray controls escape vigor from innate and conditioned threats

Weisheng Wang, Peter J. Schuette, Mimi Q La-Vu, Anita Torossian, Brooke C Tobias, Marta Čeko, Philip A. Kragel, Fernando MCV Reis, Shiyu Ji, Megha Sehgal, Sandra Maesta‐Pereira, Meghmik Chakerian, Alcino J. Silva, Newton Sabino Canteras, Tor Dessart Wager, , Avishek Adhikari

This study identifies the dorsal premammillary nucleus as a central node in the escape network by showing its role in controlling escape vigor from both innate and conditioned threats in mice and suggesting a similar pathway in humans.

Dorsal Periaqueductal gray ensembles represent approach and avoidance states

Fernando MCV Reis, Johannes Y. Lee, Sandra Maesta‐Pereira, Peter J. Schuette, Meghmik Chakerian, Jinhan Liu, Mimi Q La-Vu, Brooke C Tobias, Juliane Midori Ikebara, Alexandre Hiroaki Kihara, Newton Sabino Canteras, Jonathan C. Kao, Avishek Adhikari

The paper identifies threat-approach and threat-avoidance ensembles in the dPAG of mice and shows they encode distinct behavioral states.
