I am investigating how different neural networks within the brain process emotional visual stimuli, such as fearful faces. Specifically, I am looking at the amygdala and visual cortex and how their neural connections are modulated by spatial frequency and emotion. To do this, I am using various neuroimaging techniques, including magnetoencephalography (MEG) and dynamic causal modelling (DCM).
- Emotion: through what neural networks does sensory input evoke emotion?
- Consciousness: which neural mechanisms are involved in bringing emotion in or out of awareness?
- MEG & DCM: using the temporal and spatial resolution of MEG in combination with DCM to answer questions about when and how neural areas communicate with one another.
