Lecture 16 Flashcards
What is the difference in sensors in technical systems compared biological organisms?
qewwqe
What is the difference between the systems which control manoeuvrability in jet fighters and in flies? What are the properties of this?
qweqwe
What is a key feature of biological information processing?
werwer
What is the closed-loop nature of sensorimotor control? What are the different steps?
qweqwe
What affects the closed-loop of sensorimotor control? How does it affect it?
wqewqe
What are the different sensors measuring state changes in flies?
wqewr
What are the similarities between all of the different sensors measuring state changes in flies? What are the general properties?
weqew
What do neuronal matched filters do? What is an example?
wqeqwe
Why does the fly need 2x10 matched filters to cover horizontal rotations?
wqeqwe
What is the exact orientation of these horizontal rotation axes?
weqwe
What are natural modes of motions? What is an example?
qweqwe
What is a Dutch roll? What are the properties? What could the problem be?
weqwe
What does the approximation of the Dutch roll look like? What would happen at different phases of this optic field?
wqeqwe
What happens in the different phases of the Dutch roll in the VS cells? However what criteria needs to be fulfilled?
erwer
As there are more axes there, what can they do?
wewqe
How does the variance of the response change depending on the strength/direction of the stimulus?
werw
Why does this occur?
wqewe
What is the consequence of this occurring?
wewe
What are the benefits of sensing the modes of motion? What does it do?
adeqw
What are the different states in a fly which affect the way in which visual motion is processed in biological systems?
wqeqe
What is a fundamental constrain in sensorimotor control and visual motion processing?
wqeqe
What is the motion vision pathway processing dependent on? What is the experiment set up to show this?
wqeq
What were the results of this experiment? What did it show?
qwqe
Why does it make sense that the movement of the fly has an impact on the processing of the optic flow?
werwe
What is the difference in sensitivity to higher temporal frequencies in walking flies and stationary flies? Why does this difference occur?
wqeqe
What is the modulation of the temporal frequency tuning dependant on? What was the experiment done to show this?
wqeqw
What did the experiment show? What was actually happening to the fly and where was the energy showing?
wqeq
Which state is therefore more important when affecting vision motion processing?
weqwe
How does state-dependant information processing minimise energy expenditure?
qweqew
How do the actions between the compound eyes and the halteres differ?
we
How does the transfer functions symbolising the haltere system work?
wqewe
What is the speed property of the haltere system?
wqeqwe
What happens in a very fast whole body rotation of a fly in the haltere and compound eye systems?
qwewe
Why is the haltere system a benefit for the compound eye system?
werwer
What are the two components of the controller system? How do they interact?
wqewq
What happens to the system when there is no compensation happening? What happens if the halteres and compound eyes are both intact? What happens if the halteres are removed?
wewr
What does this show?
wqewe
What is the summary of the whole lecture? What is he dynamic range fractioning and the strategy of the 2 Degree of Freedom control?
