14:15-15:00: KeyNote in Lecture Theatre, A01Sensory coding

Petersen R

The dominant paradigm for conceptualizing the neural basis of sensory processing has been that sensory stimuli (e.g., touch on the skin) causes transduction in peripheral sense organs which, in turn, triggers action potentials which travel along a series of relays along the ascending sensory pathway en route to the cerebral cortex. This paradigm is routed in classic experiments on anaesthetized animals but is being challenged thanks to new methods developed for the study of sensory processing in awake, behaving animals. This lecture will consider these developments through recent work on the whisker system.
