Correlation-based model of artificially induced plasticity in motor cortex by a bidirectional brain-computer interface

Fig 6

(A) Network with group b subdivided into two subgroups: stimulated neurons (b^†, red) and unstimulated neurons (b^∘, white). (B) Top: plots of equilibrium synaptic strengths between group a and both subgroups of b in normal activity and under spike-triggered stimulation (left/right resp.). Proportion of stimulated neurons is set to ρ = 0.5. Bottom: Plot of relative synaptic changes between equilibria: . Control group c not shown. (C) Relative synaptic changes as a function of proportion of neurons in group b receiving stimulation ρ. Plotted are subgroup averaged synaptic changes for synapses from a to b^† and b^∘ and from a to entire group b. (d^† = 30 ms)
