Invariant neural dynamics drive commands to control different movements

Posted by klaurent May 14, 2023May 23, 2023Columbia

Kavli Affiliate: Rui Costa | Authors: Vivek Ravindra Athalye, Preeya Khanna, Suraj Gowda, Amy L Orsborn, Rui M Costa and Jose M Carmena | Summary: It has been proposed that the nervous system has the capacity to generate a wide variety of movements because it re-uses some invariant code. Previous work has identified that dynamics […]

Social experiences shape song preference learning independent of developmental exposure to song

Posted by klaurent May 11, 2023May 23, 2023Columbia

Kavli Affiliate: Sarah Woolley | Authors: Erin Mckenzie Wall and Sarah Cushing Woolley | Summary: Communication governs the formation and maintenance of social relationships. The interpretation of communication signals depends not only on the signal’s content, but also on a receiver’s individual experience. Experiences throughout life may interact to affect behavioral plasticity, such that a […]

Allosteric regulation of TRPV1 by the inflammatory lipid, LPA

Posted by klaurent May 11, 2023May 23, 2023UCSF

Kavli Affiliate: Yifan Cheng | Authors: William Randall Arnold, David Julius and Yifan Cheng | Summary: Transient Receptor Potential Vanilloid 1 (TRPV1) is a tetrameric cation channel expressed in primary afferent neurons, where it contributes to thermosensation and nociception. TRPV1 is a polymodal signal integrator that responds not only to heat, but also to inflammatory […]
