ABSTRACT
 "n"nThe availability of multimodal imaging techniques enables the acquisition of both structural and functional information of the brain, and it opens a unique window for revealing the brain activity and connectivity in neuro-psychiatric disorders.  The current lecture will review some of the most often used imaging modalities, with particular emphasis on MRI, in the research field of major neuro-psychiatric disorders from the functional perspective. Diffused tension image shows the white matter in vivo and provides us with useful parameters such as FA and ADC to assess the brain tissue integrity. Perfusion MRI helps to assess the cerebral blood flow relevant to functional alteration. BOLD fMRI is readily available for the functional brain assessment in psychiatry with task and non-task design (i.e. resting-state fMRI). The topic of fMRI will be focused, and in particular, the resting-state fMRI which has recently attracted considerable attentions and has shown potentials in future clinical applications. The current lecture will specifically focuse on the recent advances of MR imaging research in epilepsy, schizophrenia and major depressive disorders.
