Lau lab focuses on the dynamics of neuronal synapses and networks, and the neural circuitry mechanisms underlying brain disorders, especially those related to emotional stress.
We employ electrophysiological and optical approaches to study the dynamics of neuronal network in vitro and in vivo. Pharmacological and optogenetic manipulations are used to modulate neuronal circuit dynamics and to establish animal models of emotion-related disorders, such as anxiety, depression, and autism. To systematically dissect neural circuits involved in such disorders, we also develop and apply high-throughput system-wide mapping techniques based on tissue clearing and high-speed 3D imaging (VISoR) in collaboration with Dr. Guoqiang Bi’s group.
Current research directions include:
(1) Emergence of reverberatory activity with conserved firing patterns in neuronal networks through activity-dependent synaptic plasticity;
(2) Brain-wide activity mapping and neural circuitry mechanisms in animal models of depression, anxiety, and autism;
(3) The mind-body problem – how mental conditions interact with functional and diseased states of internal organs through central-peripheral connectivity.
