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
- dorsal ventral organization of descending neurons corresponds to motor output
muscles involved with flight
- anatomy of wing muscles
- indirect flight muscle organization
- the pleurosternal muscle tensions the thorax
- the mechanical power calculation of the indirect flight muscle
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
- wing kinematics during flight are constrained by a max power output
neural control of flight
- DLMn activity drives linear changes in wing beat frequency
- DLMns adjust myoplasmic calcium levels to control wing power
- splayed DLMn firing stabilizes wingbeat frequency
- the DLMns compose a minimal flight CPG
- weak electrical coupling between DLMns favors splayed firing pattern
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
- DNg02 activity increases wing beat amplitude during flight
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
connectomics
- asymmetry and inconsistencies in the connectome - why dvm2 gets little input. right vs left asymmetry
