Neuron Preview Taken out of Context: A Novel Cognitive Role for a Premotor Circuit
We developed a cognitively demanding task to study flexible decision making in mice using electrophysiological, imaging, optogenetic, and computational methods. A motor area, previously thought to primarily guide movement, computes the decision locally and represents the perceptual information in a novel population of Layer 2 cells.

We performed the first genetic characterization of command-like neurons for parental behavior in vertebrates. This study laid the groundwork for further examination of the circuitry and neuronal populations. This body of work was recognized by the 2021 Breakthrough Prize in Life Sciences.

Urocortin-3 neurons in the mouse perifornical area promote infant-directed neglect and aggression. Elife 10, e64680 (2021). [Link] [PDF]
We uncovered the genetically defined neuronal population critical for infant-directed aggression. Together with my study of the galanin neurons, we provided the entry points and a new framework to investigate the positive and negative regulation of parenting.

We demonstrated the transformation of a representation of odor identity in piriform cortex into transient and persistent representations of value in the prefrontal cortex.

We identified 7 vomeronasal receptors and 2 compounds responsible for infant-directed attack in mice. These attacks rely on the combination of parental and infant chemical cues as well as distinctive infant morphological traits.
