DESCRIPTION:Speaker: Steffen Wolff\nhosted by Sandra Siegert\nAbstract: Our
  daily activities are largely built from complex sequences of movements\, 
 whether it is tying our shoes\, serving a tennis serve or playing the pian
 o. The ability to perform such actions\, often with little mental effort\,
  depends on the distributed motor network in our brains. While many indivi
 dual components of this network have been identified\, less is known about
  their specific roles and how they interact during learning and execution 
 of motor skills. I am addressing these questions by training rats in a tim
 ed lever-pressing task that produces complex and highly stereotyped moveme
 nt sequences. I am probing the contributions of individual brain regions a
 nd their inter-connections by recording and manipulating their activities.
  In my talk\, I will show that the basal ganglia\, specifically the dorsol
 ateral striatum (DLS)\, play a central role in the acquisition and executi
 on of motor skills. I will further describe the specific roles of cortical
  and thalamic input to the DLS in these processes and suggest a circuit le
 vel model of skill learning in which motor cortex guides plasticity at tha
 lamo-striatal synapses.While these results provide fundamental insights in
 to learning and execution of a single motor skill\, real life is more comp
 lex. How does the motor network meet the challenge of learning many motor 
 skills in parallel? Do individual skills influence each other? Does learni
 ng to play tennis affect my table-tennis skills? My previous results provi
 de me with a foundation for studying these questions\, and in my talk I wi
 ll propose ways to study learning and memory in a broader and more realist
 ic context.
