Rebecca Todd, Ph.D.
My doctoral research focused on mapping brain activation patterns underlying emotional processing in young children, as well as studying individual differences in temperament and the development of self-control in childhood. Current research interests include investigating the effects of emotional arousal on the subjective experience of perceptual vividness following traumatic experience, and links between perceptual vividness and emotional memory. I am also interested in the influence of positive emotional states on both perceptual and conceptual processing, and the neural mechanisms underlying such influences.
My general interest is in the field of cognitive neuroscience of memory and more precisely in the characterization of the similarities, differences and interactions between the semantic and episodic systems. Recent interests include personal semantic memory and how this type of memory may be situated in relation to the two broad systems of declarative memory. This involves investigating the neural bases of personal semantic memory with event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI) and comparing them with those of general semantic and episodic memory. Other interests include the nature of semantic representations in the brain, the neural correlates of consciousness, and the similarities between perception and imagination.

I still pretty much look like this. But these days, in addition to my love of Lego and comfy sleepwear, Iām also into cognitive and clinical neuropsychology. Iām especially interested in the idea of adaptive neural networks, and the impact of white matter injury on networks involving the frontal lobes. To study brain changes associated with injury, recovery, and neuroplasticity, I work with people who have had a traumatic brain injury (TBI) or have multiple sclerosis (MS). I have used fMRI, and am now using EEG, to look at the brain bases of attention and executive abilities in these populations, particularly as these relate to self-regulation and goal-driven behaviour. As part of the Levine Lab Rehab Sub-Committee, I am also running a RCT comparing two programs we have designed for people with MS who have deficits in attention and executive abilities. All of which leaves me little time to play with my Lego, but I guess that's (part of) the price of a PhD...
