Low Rheobase cells are found in both males and females at all
ages examined
LR cells are present in both adolescent and adult mice, suggesting this
highly intrinsically excitable cell is not a transient developmental
phenotype (Figure 4A). LR cells are found in both male and female mice
(Figure 4C). Thus, these neurons are the dominant cell type in the
superficial granular retrosplenial cortex, consistent across age, sex,
and long-axis of the RSG.
