SUMMARY:Basil el Jundi (Norwegian University of Science and Technology\, Tr
 ondheim\, Norway): Unravelling the migratory compass of monarch butterflie
 s
DESCRIPTION:Basil el Jundi: Each fall\, millions of monarch butterflies mig
 rate over up to 5.000 km from North America and Canada to their overwinter
 ing habitat in the mountain ranges of Central Mexico. To maintain their di
 rection\, these butterflies rely on the sun as their main orientation refe
 rence. In my research group\, we are interested in understanding how these
  fragile butterflies use the sun for orientation to maintain a directed mi
 gratory direction and how they master such a remarkable migration despite 
 exhibiting a brain that is smaller than a grain of rice. We are studying t
 he sun compass of monarch butterflies through behavioral and neuroanatomic
 al techniques\, as well as through electrophysiological approaches\, such 
 as multichannel tetrode recordings from tethered-flying butterflies. Our r
 ecent results show that the butterfly’s internal sun compass consists of
  head-direction neurons\, steering neurons\, as well as neurons that repre
 sent the animal’s goal direction. Together\, these neurons establish a n
 avigation network in brain that represents the animal’s current heading 
 and the desired goal direction\, generating steering commands whenever the
  butterfly deviates from its migratory course.\n\n\n\n\nIOSSB Seminar\n\n&
