DESCRIPTION:Dan O'Connor\, The Solomon H. Snyder Department of Neuroscienc
 e\, Johns Hopkins University School of Medicine\, Baltimore\, USD\nI will 
 discuss work from my laboratory using the mouse whisker system to explore 
 the neural basis of touch perception. Tactile processing serves upcoming a
 ctions\, which depend on behavioral goals. However\, it remains unclear ho
 w the action context in which tactile inputs occur affects their processin
 g in the brain. It also remains unclear how neural signals related to move
 ments interact with sensory signals in somatosensory cortex. We have devel
 oped a cross-modal attention task in which head-fixed mice flexibly switch
 ed between responding to tactile stimuli in the presence of visual distrac
 tors\, or to visual stimuli in the presence of tactile distractors\, using
  licking movements to the left or right side in different blocks of trials
 . I will discuss our work using this task together with single-unit record
 ings and optogenetic perturbations of somatosensory cortex\, as well as op
 togenetic perturbations of orofacial motor cortex\, to investigate how sen
 sory and motor signals combine in somatosensory cortex\, and how the actio
 n required of a tactile stimulus affects its processing. \n \n
