Frequency of subthreshold membrane potential oscillations change systematically along the DV but not along the ML axis.

<p>(A and B) Examples of SMPOs in the normal ACSF in a dorsal (A) and a ventral cell (B). The SMPO frequency was higher in dorsal cells than in ventral cells. (C and D) Examples of SMPOs in carbachol (10 µM) in a dorsal (C) and a ventral cell (D). (E) Color plot of the SMPO frequency at different positions in two-dimensions (DV and ML) of anatomical space in normal ACSF. (F and G) SMPO frequency along the DV and ML axis, respectively, in normal ACSF. (E) Color plot of the SMPO frequency at different positions in the two-dimensions (DV and ML) of anatomical space in carbachol. (F and G) SMPO frequency along the DV and ML axis, respectively, in carbachol.
