Saved experiments

The Lab

A picture goes in. The model responds. What can the change tell us?

Fly One is a computer model of the parts a fly uses to see. These are not measurements from a living fly.

Can a new picture wipe away the old response?

The change did not pass the test for wiping away the earlier response.

LOCKED RUN · The plan was set before the run. This does not mean the answer is confirmed.

A still from the saved run. Some experiments contain several views.

What changes when a sight-cell group is turned off?

Turning off the whole group changed the response more, but the groups had links of different strengths.

EXPLORATORY · An outside reviewer checked the numbers on this card and asked for plainer wording. The result is still exploratory.

What is left after a picture ends?

The mixed-up picture and grey-only run left almost the same response after the picture ended.

What changes when links back to earlier cells get weaker?

The response changed, but weakening every link changed it more.

What happens when moving stripes fade away?

Mixing up the fading picture changed the response more than stopping or holding it.

What happens when the model makes its next picture?

Mixing up that added link changed the response more than removing it.

Does the same picture give the same response?

The response was exactly the same, as expected for this computer model.

What changes when the movie runs backward?

Reversal changed the response only a little more than mixing up the picture.

What happens when light and dark get much stronger?

The mixed-up strong picture changed the response more than the ordered one.

Can an added picture link change another model?

A mixed-up link changed the receiving model almost as much.

Does a faster picture make the cells change faster?

Some cell groups followed the faster picture, while a slow starting change affected other readings.

Can the planned picture help guess the response?

The guesses beat the tested simple guesses on this movie, with the current picture given to the rule.

Does the response last after the picture ends?

The early burst faded away, and no test movie passed the later check for a lasting trace.

How unusual is turning off a sight-cell group?

The saved change was at the high end of the tested random changes.

Does a picture link stand apart from mixed-up links?

With the link turned off, every version gave the same response. Across the full test, no setting passed both required comparisons.
