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

(A) ICMS with baseline connections. (B) ICMS after spike-triggered stimulation. Top left panels: Connectivity matrix J. Top right panels: Raster plot of entire network as in Fig 1. Bottom black bar shows a 50 ms stimulation of all neurons in group a at 100 Hz. Bottom: Filtered responses of group projections. Columns designate neural groups in MC being stimulated (see e.g. A for stimulation of group a) and rows designate the output EMG Mα evoked from each group, respectively. Circle indicates the biggest change induced by spike-triggered conditioning.
