报告摘要:
Our amazing brain, the most complex and dynamic network found in nature, is composed of billions of neurons with trillions of dendritic spines and synapses. Interestingly, individual spines and synapses are unique and display different electrical properties, posing a daunting challenge to neurotechnology for mapping brain activity with single-synapse resolution to understand how these fundamental neural network building blocks behave to achieve higher brain function. In response to this challenge, we are creating a novel graphene optoelectronic probes to measure the activity of individual spines and synapses throughout complex neuronal networks. We culture neuronal networks and whole retina using graphene-based microfluidic platforms and using scanning photocurrent microscopy to scan large areas of neural networks with single synapse resolution. I will discuss the demonstrated ultrahigh spatiotemporal resolution of this powerful neurotechnology, which could lead to an in-depth understanding of cognitive behavior and new therapeutic approaches for treating neuronal and psychiatric disorders.
In addition, I will discuss a few more projects on-going in my research group, including biomechanics and mechanobiology of normal and cancer associated fibroblasts, as well as some recent progress in understanding thermal transport through nanowires with fine structures.
