• Dendritic fluorescence imaging showed that Ca2+ channels of several subtypes mediated the AP-evoked fluorescence transient in the proximal (100-170 microns) apical dendrite. The fluorescence resulted from Ca2+ entry through L, N, and P-type channels, and through Ca2+ channels (R-type) not sensitive to L-, N- and P-type Ca2+ channel blockers Show Other
