Repetitive translocation of αCaMKII to dendritic sites near synapses. Time-lapse imaging of a neuron expressing mGFP-αCaMKII showing repetitive accumulation of CaMKII in dendritic hot spots near synapses during multiple 0Mg2+/Gly stimulations (3–5 min each). Frames were taken every 20 s with a CoolSnap-HQ camera (Photometrics) on an Axioskop FS2 microscope (Achroplan 63x 0.95 NA objective; Carl Zeiss). Related to Fig. 1.
