Multiple Mechanisms of Consciousness: The Neural Correlates of Emotional Awareness

Journal of Neuroscience July 28, 2010 Jayna M. Amting, Steven G. Greening, Derek G. V. Mitchell

Emotional stimuli, including facial expressions, are thought to gain rapid and privileged access to processing resources in the brain. Despite this access, we are conscious of only a fraction of the myriad of emotion-related cues we face everyday. It remains unclear, therefore, what the relationship is between activity in neural regions associated with emotional representation and the...

Visual awareness, emotion, and gamma band synchronization.

Cerebral Cortex August 1, 2009 Qian Luo, Derek G. V. Mitchell, Xi Cheng et al.

What makes us become aware? A popular hypothesis is that if cortical neurons fire in synchrony at a certain frequency band (gamma), we become aware of what they are representing. We tested this hypothesis adopting brain-imaging techniques with good spatiotemporal resolution and frequency-specific information. Specifically, we examined the degree to which increases in event-related...
