Emotional brain function: When, Where and How?

Proposal details

Title: Emotional brain function: When, Where and How?
Research Area(s): Emotion and Self Regulation
Background: This study is an ARC discovery project. It addresses the issue of brain specialisation for emotional function in by addressing the following unresolved issues: 1) Can we identify where specific networks involved in perceiving different facial emotions are located using fMRI technology? 2) Can we determine when these networks show maximal activation and integration using ERPs and the new Gamma Synchrony measure? 3) How are the networks involved in facial emotion perception modulated? Can we distinguish a different pattern of network activation for emotions appraised as ‘significant’ or ‘novel’ (with-SCRs) by individual our new protocol for simultaneous electrodermal recording?
Aims: 1) The basic emotions of fear, anger, disgust, happy, sad will be associated with specialized spatial (fMRI) networks, compared to neutral. The networks associated with more survival-oriented emotions (fear, disgust, anger) will be more localised than those for more socially-oriented emotions (happy, sad). 2) Basic emotions will be distinguished by ERPs and Gamma synchronisation in different temporal windows. Survival-oriented emotions will show earlier ERPs and synchronization. 3) When fMRI activation and Gamma Synchrony is sub-averaged by simultaneous SCRs,'with SCR' responses with show greater activation and greater synchrony than ‘without-SCR’ responses.
Method: 1. FMRI and simultaneous SCR recording to Gur face stimuli (conscious and non-conscious presentations) 2. ERPs, Gamma and simultaneous SCR recording in an equivalent task (for fear vs happy)
