DESCRIPTION:Miguel Maravall\, Sussex Neuroscience\, University of Sussex\,
  Brighton\, UK\nTo make sense of the world around us\, the brain must disc
 riminate stimuli that are structured in space and time. In the tactile sys
 tem\, information about the identity of a stimulus is collected as a serie
 s of events (contacts\, vibrations…) concatenated over time. The ability
  to encode individual events faithfully and precisely is central to tactil
 e function. Work from my lab investigates principles of sensory encoding t
 hat underlie these capacities\, using the rodent whisker system as a model
 . Neurons in the whisker system are sensitive to features of whisker motio
 n over time\; at each stage in this sensory pathway\, different neurons ar
 e selective to distinct features\, giving rise to rich and diverse populat
 ion codes. In the whisker primary somatosensory cortex\, cells selective t
 o different stimulus dynamical features are interspersed in space. Neurona
 l diversity underpins a robust collective representation of texture.\nThes
 e findings have implications for how temporally patterned sensory stimuli 
 are processed. To explore this\, we have recently developed a novel sequen
 ce discrimination task. We have found that mice as well as humans can dist
 inguish between stimuli that differ only in their temporal patterning. In 
 this talk I will give an overview of our work and detail our latest findin
 gs.\n
