 Y2KzJuMVl6UT09\n Zoom: \n Abstract: \n Details: \n Through natural selecti
 on\, animals evolved the abilities required to survive in a complex dynami
 c world: they accurately perceive their surroundings\, map their environme
 nt and localize themselves and others within it\, develop flexible policie
 s to achieve various goals\, and translate these policies into motor actio
 ns. The natural mechanisms executing these tasks outperform currently exis
 ting artificial systems. They are implemented in hierarchical networks of 
 closed circuits composed of complex non-linear dynamic elements – neuron
 s and synapses. In this talk\, I will show how frameworks and tools of eng
 ineering are used to investigate these mechanisms in the weakly electric f
 ish\, an animal that provides unparalleled access to the study of sensing\
 , learning\, and control in three-dimensional space. A novel method I deve
 loped enables continuous\, long-term recording of motor\, sensory and neur
 onal signals in freely swimming fish. I used this method to study a brain 
 circuit implementing an internal forward model involved in Adaptive Noise 
 Cancelation of incoming sensory signals. I have found that such cancelatio
 n is critical to the animal’s ability to perceive and that its implement
 ation requires both motor command and sensory feedback signals. I will dis
 cuss future directions related to how the brain constructs an internal map
  of the environment and localize within it. Insights generated about these
  processes in natural systems will be used to advance artificial sensing a
 nd autonomy in terrestrial\, aquatic\, or aerial systems.\nZoom Meeting
