Sensory-Motor Modulations of EEG Event-Related Potentials Reflect Walking-Related Macro-Affordances

One fundamental principle of the brain functional organization is the elaboration of sensory information for the specification of action plans that are most appropriate for interaction with the environment. Using an incidental go/no-go priming paradigm, we have previously shown a facilitation effect...
