Our visual system is capable of inferring the structure of 2-d images at a resolution comparable (or, in some tasks, greatly exceeding) the receptive field size of individual retinal ganglion cells (RGCs). Our capability to do so becomes all the more surprising once we consider that, while performing such tasks, the image projected on the retina…

Adam Cohen Depts. of Chemistry and Chemical Biology and of Physics Harvard University Abstract: To probe neural function, one would like to monitor the simultaneous electrical activity in a large number of neurons, with high resolution in space and time. Genetically encoded optical indicators of membrane potential are a promising…

Speaker: Dan Fu The George R. Harrison Spectroscopy Laboratory Massachusetts Institute of Technology Abstract: Modern microscopy has long been the driving force in tackling biological and biomedical problems. Key innovations in new microscopy technologies are focused on three different aspects: resolution, contrast and speed. Fluorescence…
