Figure 7. Deprivation of sensory experience results in silencing of spines.

Figure 7

(A) Example spine glutamate uncaging experiment showing neighboring AMPA receptor functional and AMPA receptor silent spine on a section of dendrite from a stellate cell (from an undeprived barrel). (B) Spine AMPA receptor current enrichment vs. spine head width for control (undeprived; black) and deprived (red). Open circles are those spines determined to be silent. (C) Pooled data for spine AMPA receptor current enrichment for control (undeprived; black, n=43) and deprived (red, n=10) (mean±sem). (D) The proportion of silent spines in control (undeprived, black) and deprived (red).
