Neuromodulation means modification of the neurocognitive state of a person. We neuromodulate when we become fatigued, or excited, or when we train a skill such as meditation. In one session of transcranial direct current stimulation (tDCS) we can enhance the excitability of a region of cortex such as the dorsolateral frontal cortex which may be underactive in depressed individuals. We can also enhance the excitability of a region of cortex using neurofeedback (NFB). Typically in NFB the client’s brain is exposed to information about its internal states and timing. Certain state changes are signaled by sensory feedback so that neuromodulation might be operantly conditioned by the clinician. NFB may take longer than tDCS to achieve neuromodulation of excitability, but it includes training of a variety of state changes. Typically mindfulness meditation takes longer than NFB, but in the end some practitioners can rapidly activate gamma in different cortical regions as needed [1]. This website and its companion, Cortexercise, discuss technology-assisted self-regulation (TASR), or technology- assisted self-realization if you prefer.
