Cycloplegia Improves the Inter-Optometrist Repeatability of Subjective Refraction

Photonics
Background: Since accommodation may be a source of error affecting the inter-optometrist repeatability of subjective refraction, this study investigated whether the use of cycloplegia could improve this repeatability.

Low-frequency local field potentials and spikes in primary visual cortex convey independent visual information [PDF]

, 2008
Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli.
