§§ flight motor control notes

organizing notes i take just to keep track of things for now

background

• model organisms for studying insect flight
• hemilineages provide a functional and anatomical classification for neurons in the vnc

muscles involved with flight

• anatomy of wing muscles
• the pleurosternal muscle tensions the thorax

flight mechanics

• the thorax mechanically links wings and halteres through oscillations
• flying insects decouple wings from thorax for steering
• wings have synchrony during both initiation and cessation of flight

descending control

• three dopamine neurons in the VNC coordinate wings during flight
• looming stimulus evokes opposite behaviors depending on behavioral state
• looming feature detectors convey visual information to VNC for takeoff response

neuromodulation

• neuromodulation of flight
• ascending histamine neurons participate in flight feedback loop
• octopamine activity increases during flight
• coordinated activity of the flight power muscles are critical for flight

examples of flight cessation

• bio robotic research coarsely demonstrate flight cessation with implanted neural stimulations in large insects

connectomics

• asymmetry and inconsistencies in the connectome - why dvm2 gets little input. right vs left asymmetry
