From: Short-term dynamics of input and output of CA1 network greatly differ between the dorsal and ventral rat hippocampus

Fig. 7

The dynamic range of frequency-dependent modulation of synaptic input (fEPSP) and neuronal output (PS) greatly differs between the dorsal and the ventral hippocampal circuitry. The two graphs show the combined steady-state changes in fEPSP and PS as a function of stimulus frequency. Data are obtained at suprathreshold stimulation intensity. The highest and the lowest value of each 3D plot (corresponding to intense facilitation and depression respectively) are marked by red and blue color respectively, as indicated in the color scale bar. In the DH the changes of both fEPSP and PS range from robust facilitation to almost complete depression. On the contrary, the steady-state responses in the VH (both fEPSP and PS) are mostly depressed, showing only a minor facilitation at low stimulus frequency
