Our new paper is out in Science.

We identified a subgroup of cholinergic neurons that mediate sensory modality-specific attention. They change their funcitonal properties within secs of behavioral context change.

Congrats to Bin for the great thesis, and the team!

Cholinergic feedback for modality- and context-specific modulation of sensory representations
The brain’s ability to prioritize sensory information is crucial for adaptive behavior, yet its mechanisms remain unclear. We investigated basal forebrain cholinergic neurons modulating olfactory bulb...

Excited to share that I just published my first ever first-author paper in Psychoneuroendocrinology in the Marler Lab. We found that oxytocin may impair wound healing when animals are isolated.

Oxytocin impairs wound-healing during social isolation but not social living
Social isolation hampers immune system function, and the biological mechanisms driving this effect remain understudied. We hypothesized that oxytocin …

This was a great paper to work on! The effects of intranasal oxytocin are context dependent - when California mice are isolated, oxytocin *increases* wound inflammation in a dose-dependent manner. Exciting implications for how neuropeptides interact with the immune system!
