Figure 6. Short Term Plasticity in cortical layer 5 microcircuitry.

Figure 6

A Short term facilitation of the pyramidal-Martinotti synapse, shown is the activity of the Martinotti cell when the pyramidal cell is stimulated at 20 Hz, 40 Hz and 70 Hz. B Two pyramidal and one Martinotti neuron with STF, the Martinotti neuron is stimulated at 70 Hz with adaptive post-synaptic IPSPs at neurons Inline graphic (black) and Inline graphic (blue). C Complete microcircuit with STF, except the Inline graphic to Inline graphic synapse with STD. Inline graphic is stimulated at 40 Hz which results in a single AP in Inline graphic that terminates the stimulation burst in Inline graphic and causes a large IPSP in Inline graphic.
