Title: Sensorimotor control in walking fruit flies and snow flies


Abstract: In Part I of my talk, I will present evidence that sensory
signals in the axons of Drosophila leg proprioceptors are predictively
suppressed during walking. Suppressing expected proprioceptive
feedback caused by self-generated movement increases sensitivity to
unexpected external perturbations. In Part II, I will discuss extreme
cold tolerance in the snow fly (Chionea), a native of the Pacific
Northwest (USA). I will present evidence that snow flies can sustain
coordinated walking behavior at internal temperatures of -10° C.

About Neuroscience Seminars

Neuroscience seminars at the QBI play a major role in the advancement of neuroscience in the Asia-Pacific region. The primary goal of these seminars is to promote excellence in neuroscience through the exchange of ideas, establishing new collaborations and augmenting partnerships already in place.

Seminars in the QBI Auditorium on Level 7 are held on Wednesdays at 12-1pm, which are sometimes simulcast on Zoom (with approval from the speaker). We also occassionally hold seminars from international speakers via Zoom. The days and times of these seminars will vary depending on the time zone of the speaker. Please see each seminar listed below for details.
