| Research Abstract |
To establish chronic in vivo two-photon calcium imaging, we generated transgenic mice that stably express a genetically-encoded calcium sensor GCaMP4 in layer 5 of cortex and CA1 of hippocampus. Our in vivo two-photon imaging confirmed that the fluorescence of GCaMP4 in hippocampal CA1 pyramidal cells of these mice increased rapidly and substantially in response to pharmacologically-induced elevation of neuronal circuit activity. These transgenic mice will thus become a valuable tool for longitudinal imaging studies of learning-induced neuronal circuit plasticity in the brain.
