The psychophysiology of smell: how we smell, why we smell and what differentiates different smell qualities. We are also investigating the function of smell as a signalling medium in humans (human pheromones).
We use evoked potential recording, threshold testing and physiological monitoring (e.g. skin resistance, heart rate etc).
Smell has an affective ability by virtue of conditioned associations. However, smell is first analysed by the brain along two dimensions; hedonicity and intensity. We are investigating the psychophysiological responses to pleasant and unpleasant smells and determining the implications this has for olfactory processing in the brain. Some responses seem to be hard-wired while others exhibit remarkable plasticity; we are investigating the extent to which the olfactory system can learn to smell and how it adapts to smell using EEG, psychometric tests and physiological monitoring.
