Pie Chart from Scientific Research

Left, proportion of different types of CA3 neurons phase locked to distal CA1 theta oscillations: the phase-discriminating neurons (in green, with a phase-locking angle differing between repeated and non-repeated odors) and non-phase-discriminating neurons (type I [in blue] and type II [in gray]). Type I neurons were phase locked to the same angle of the theta phase oscillations for repeated and non-repeated odors. Type II were phase locked for only one type of stimulus (gray). About half of the CA3 neurons phase locked to CA1 theta (51%) could discriminate between repeated and non-repeated stimulii.e., were phase-discriminating neurons. Right, CA3 phase-discriminating neurons (green on the left) could be subdivided into three groups: the majority of neurons (>70%) were phase locked to different phases of distCA1 theta oscillations for repeated and non-repeated odors, while about 20% were phase locked for non-repeated and 10% for repeated stimuli.
