How do simple cells acquire the property of orientation selectivity?

Convergence of geometrically aligned LGN receptive fields

Feedback from "grandmother" cells

Convergence of edge and bar detectors

The tilt after-effect implies that the perceived orientation of a pattern is:

Determined by the relative activity of many orientation channels

Governed by a winner take-all computational process

Shifted toward the orientation of the adapting pattern

Determined by the most active orientation channel

Respond more vigorously than either simple or complex cells

Are less orientation selective than simple cells

Is likely to result from operations at many stages of visual processing

Can be completely understood based on the receptive field properties of ganglion cells

Has no explanation based on retinal processes

Is closely related to the scintillating grid illusion

Intermediate spatial frequencies

Frequencies near the resolution limit
