Yuxiang Liu

Graduate Research Assistant at Columbia University Biomedical Engineering

Yuxiang "Andy" Liu is currently a fifth-year PhD student at Columbia University. His research focuses on understanding how noradrenergic inputs to the prefrontal cortex (PFC) and forebrain modulate animal behavior.3

Liu's recent work involves investigating norepinephrine (NE) and acetylcholine (ACh) dynamics and population neuronal activity in the prefrontal cortex during inhibitory control. He has been using fluorescent sensors to measure extracellular levels of NE and ACh in mice performing inhibitory control tasks.1

His research has revealed interesting findings, such as strong coherence between prefrontal NE and ACh signals at 0.4-0.8 Hz, and the impact of chemogenetic inhibition of locus coeruleus neurons on inhibitory control performance. Liu's work suggests that NE-ACh phase synchrony is a critical neuromodulatory feature with important implications for cognitive control.1

Andy has also employed advanced techniques like Neuropixels recordings and demixed principal component analysis (dPCA) to understand the effects of NE-ACh synchrony on prefrontal population activity. His findings indicate that the locus coeruleus modulates inhibitory control through its collective effect with cholinergic systems on population activity in the prefrontal cortex.1

Liu has presented his work at scientific conferences, including the Society for Neuroscience (SfN) meeting, where he has shared posters on his research.2
