Figure 7.
Experience-dependent dendritic arbor structural plasticity and functional plasticity are correlated in individual neurons. A. Top: Schematic of visual stimulation protocol and imaging time points. Bottom: Projected images (upper row) and reconstructions (middle row) of the complete dendritic arbor and visually-evoked Ca++ responses (bottom row) of a tectal neuron at T1, T2 and T3. Scale bar: 2 sec, 10% dF/F0. B. Scatterplot of changes in total branch tip number (TBTN) versus changes in peak Ca++ amplitude (dF/F0) in response to either dark or STVE in individual neurons (n=10 neurons, 18 data points). r = 0.584, p<0.05, Pearson correlation. C, D. Scatterplots overlaying changes of peak Ca++ amplitude (C) and TBTN (D) of individual inhibitory neurons shown in B (dark pink, n=5) onto the entire datasets presented in previous figures (light pink).
