| |  All-Optical Interrogation of Neural Circuits – Free Webinar
Neural circuits display complex spatiotemporal patterns of activity on the millisecond timescale during behavior. Understanding how these activity patterns drive behavior is a fundamental problem in neuroscience, and remains a major challenge due to the complexity of their spatiotemporal dynamics. The ability to manipulate activity in genetically defined sets of neurons on the millisecond timescale using optogenetics has provided a powerful new tool for making causal links between neuronal activity and behavior. In this webinar, Dr. Adam Packer from the University of Oxford will present novel approaches that combine simultaneous two-photon calcium imaging and targeted optogenetic photostimulation with the use of a spatial light modulator (SLM) to provide ‘all-optical’ readout and manipulation of the same neurons in vivo. The power, limitations and future potential of this approach; and how it can be used to address many important problems in neuroscience will be discussed.
