Two-photon photostimulation and imaging of neural circuits. Academic Article uri icon

abstract

  • We introduce an optical method to stimulate individual neurons in brain slices in any arbitrary spatiotemporal pattern, using two-photon uncaging of MNI-glutamate with beam multiplexing. This method has single-cell and three-dimensional precision. By sequentially stimulating up to a thousand potential presynaptic neurons, we generated detailed functional maps of inputs to a cell. We combined this approach with two-photon calcium imaging in an all-optical method to image and manipulate circuit activity.
