Neural activity ramps in frontal cortex signal extended motivation during learning

Kavli Affiliate: Priya Rajasethupathy | Authors: Josue M Regalado, Ariadna Corredera Asensio, Theresa Haunold, Andrew C Toader, Yan Ran Li, Lauren A Neal and Priya Rajasethupathy | Summary: Learning requires the ability to link actions to outcomes. How motivation facilitates learning is not well understood. We designed a behavioral task in which mice self-initiate trials […]

The breath shape controls intonation of mouse vocalizations

Kavli Affiliate: Kevin Yackle | Authors: Alastair MacDonald and Kevin Yacklei | Summary: Intonation in speech is the control of vocal pitch to layer expressive meaning to communication, like increasing pitch to indicate a question. Also, stereotyped patterns of pitch are used to create distinct “words”, like the ten sounds in the murine lexicon. A […]

Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Daniel Harsono, Feng Long, Paola Pinilla, Alessia A. Rota, Carlo F. Manara | Summary: While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This paper presents dual-wavelength Atacama Large […]
