Stable ISOI but reduced wLFPs during the 3-d homeostatic phase of plasticity. (A) Example intrinsic signal images (3 × 3-mm field) during D1 whisker deflection for 3- and 7-d deprived animals and age-matched controls. (B) Mean D1 whisker response area for each condition. (C) Peak intrinsic signal (mean of four neighboring pixels) for each condition. (D) Mean wLFP waveforms for all L2/3 recordings in 3-d deprived (gray) and spared (black) columns. Shading is SEM. (E) L2/3 wLFP peak amplitude (mean ± SEM) for deprived and spared columns at varying deprivation durations. (F) wLFP amplitude ratio (deprived/spared column within each animal) for L2/3 and L4 wLFPs. *P < 0.05. **P < 0.01.
