P-DOpE probes reveal local amplification of phasic noradrenergic release in the hippocampus

Hengji Huang, Karyn Schy, Yue Liu, Alexandra L. Sommer, Jongwoon Kim, Brandon Jackson, Xintong Yang, Joanna Mattis, Earl T. Gilbert, Lijin Kevin Wang, Chelsea M. Buhler, Xiaoting Jia, Daniel Fine English, Sam McKenzie

The paper introduces a P-DOpE probe that combines optogenetics and electrophysiology for in vivo monitoring, showing it amplifies noradrenergic signaling in the hippocampus under specific conditions.

Event boundaries drive norepinephrine release and distinctive neural representations of space in the rodent hippocampus

Sam McKenzie, Alexandra L. Sommer, Tia N. Donaldson, Infania Pimentel, Meenakshi Kakani, Irene Jungyeon Choi, Ehren Lee Newman, Daniel Fine English

The paper investigates how event boundaries influence norepinephrine release and hippocampal neural representations in mice, finding that NE dynamics correlate with environmental changes and affect spatial coding.
