Train your brain to see fine shades of gray

A U of MN psychology professor Stephen Engel has been able to train individuals to see progressively lighter shades of lines on a computer screen.  Subjects were trained to improve the ability of their primary visual cortex (V1) to see progressively fainter objects flashed on a computer screen.  The researchers point out that this would be useful for a person reading Xrays.

After looking into a microscope for more than twenty years, I have found it to be helpful for looking at fungal spores.  Trained microscopists will often draw structures at the edge of the ability for an optical microscope.  The structures have later been verified with electron microscope imaging.
