What is QEEG

Neuroimaging plays a crucial role in psychiatry and mental health as it can potentially be used to identify causal factors, biomarkers of a disorder, prognosis or treatment, elucidate biological pathways along with informing and monitoring newer therapies. Early and prophylactic interventions present an emerging future direction in clinical psychiatry, and neuroimaging has the potential to help in identification of individuals at risk and monitor the effects of intervention. In the chapter an attempt is made to elaborate the concept of brain mapping, and differences between structural and functional brain imaging are discussed. The chapter focusses on advent of neuroimaging in psychiatry along with discussing the major functional neuroimaging techniques.
