	-Total absorption levels remain unaffected by the eye movements performed by the eye. This reinforces the idea that these movements are enhancing the amplification in frequency and not absolute value (for both absorption and photocurrent).		- Total absorption levels remain unaffected by the eye movements performed by the eye. This reinforces the idea that these movements are enhancing the amplification in frequency and not absolute value (for both absorption and photocurrent).

	- It is clear that eye movements amplify temporal photocurrent spectra of a scene relative to observations of the scene without eye movements. Since the visual system is more responsive to fluctuating retinal signals than the average value of the signals, the presence of eye movements amplifies viewed scenes. A similar relationship would be expected for the spectra of absorptions as well, given the proportionality of absorptions and photocurrent.		- It is clear that eye movements amplify temporal photocurrent spectra of a scene relative to observations of the scene without eye movements.

	- However, it is not clear whether there is a strong relationship between spatial frequency and retinal amplification. In fact, we saw that lower spatial frequencies were amplified more than higher spatial frequencies, which ~~was the opposite of~~ our ~~expectation, given~~ the ideas of Rucci and Victor.		- However, it is not clear whether there is a strong relationship between spatial frequency and retinal amplification. In fact, we saw that lower spatial frequencies were amplified more than higher spatial frequencies, which defied our predictions based on the ideas of Rucci and Victor.

	- Individual cone types (L, M, and S) do not show a noticeable amplification of higher spatial frequencies than lower spatial frequencies, but do provide more spectral power with eye movements than without eye movements.		- Individual cone types (L, M, and S) do not show a noticeable amplification of higher spatial frequencies than lower spatial frequencies, but do provide more spectral power with eye movements than without eye movements.
