FIGURE 1.

Schematic summary of the technological approaches used to study the functional connectivity between grafted and host neurons. Transplanted cells (colored in green) are located adjacent to the cortical ischemic lesion. For clarity and as an example, thalamo-cortical afferent projections to the graft and transcallosal projections from graft to host cortical neurons in the contralateral hemisphere are presented. Different techniques are distributed in the areas of the brain where they are applied: (A) contralateral cortex, (B) transplant, (C) thalamus. TX, transplant; CC, corpus callosum.
