Photobleaching and Photoactivation techniques
Time lapse series of images of dendrites and spines in neurons transfected with mCherry (to highlight the morphology) and a photo-activatable GFP tagged to a synaptic protein. Using a two-photon laser, a small region (circles) is photo-activated to “light up” the protein in spines and to follow its diffusion out of the spine over time. In active neurons, this protein resides for much longer time in the synapse. |
Summer School Highlights
News
Biophotonics week is an exciting series of scientific events in the beautiful city of Quebec, Canada.
A new graduate program (M.Sc. and Ph.D. levels) in Biophotonics just opened at Université Laval. The Neurophysics group was significantly involved in the creation of this program which has started in Fall 2008. |
