Figure 12. Neuronal activity modulates magnetic threshold.

Figure 12

The effect of a change in membrane potential on the MS of the pyramidal cell model used in figure 8. Location of the artificial cell relative to the center of the coil and the parameters for calculating the induced electric field as in figure 5. Cell parameters as in figure 7. A, Magnetic threshold as a function of a synaptic input Δt before stimulus onset. B, The membrane potential in the soma as a function of time. An excitatory postsynaptic potential was evoked Δt milliseconds before MS onset. C, Magnetic threshold as a function of an AP at Δt before stimulus onset. D, Membrane potential in the soma as a function of time. An AP was evoked Δt milliseconds before MS onset.
