RGS14 Suppresses CA2 Spine Structural Plasticity (IMAGE) Max Planck Florida Institute for Neuroscience Caption (Top) Averaged time course of spine volume change during the induction of spine structural plasticity (sLTP) by repetitive two-photon glutamate uncaging (top bar; 30 pulses at 0.5 Hz) in the absence of extracellular Mg2+. (Bottom) Quantification of the average volume change for stimulated spines during the sustained phases (21-25 mins) of sLTP induction.
