Multimodal Imaging of Human Brain Activity : Rational, Biophysical Aspects and Modes of Integration

Abstract EN

Until relatively recently the vast majority of imaging and electrophysiological studies of human brain activity have relied on single-modality measurements usually correlated with readily observable or experimentally modified behavioural or brain state patterns.

Multi-modal imaging is the concept of bringing together observations or measurements from different instruments.

We discuss the aims of multi-modal imaging and the ways in which it can be accomplished using representative applications.

Given the importance of haemodynamic and electrophysiological signals in current multi-modal imaging applications, we also review some of the basic physiology relevant to understanding their relationship.
