Illustration showing the effects of different types of stimulation and injury on neuronal response. The top section depicts an experimental setup with a neuron receiving stimulation and the resulting response in reward prediction, with graphs labeled "Scaling with reward prediction" comparing IPS1 and CONTRA stimulation. The middle section shows a neuron with positive contingency, demonstrating a similar setup and graphs indicating a stable response to positive contingency, with the same prediction graphs. The bottom section illustrates contingency degradation, with a neuron and graphs showing loss of hemispheric lateralization, with reduced response to stimulation in the graphs.
