Functional neuroimaging and electrophysiological techniques serve well to study spontaneous or task-related neuronal activity as correlates of specific cognitive functions in the human brain.
However, to infer causality of brain activation for cognition, the former must be manipulated experimentally. In healthy humans, this is possible with the help of non-invasive brain stimulation (NIBS) techniques.
Online approaches, assessing the immediate neural response to stimulation, can be used to quantify cortical excitability or connectivity, to interfere with ongoing spontaneous or task-related neural activity, or to modulate its level or timing, whereas offline approaches can be used to inhibit or facilitate subsequent local neuronal excitability via mechanisms of synaptic plasticity.
Importantly, NIBS techniques can also be combined with neuroimaging as well as with each other to with each other to map network responses and gain proof-of neural target engagement.
