Neury Thursday/Friday: Coloring in V4

I apologize for the delay of Neury Thursday, but last night, I went to a Kent State Freethinkers meeting on the secrets/tricks/talent of mind reading. You can watch the six part series featuring Derren Brown, an English illusionist, and Richard Dawkins. The “artistic” camera shots are quite irritating, but it’s worth the content.

Back to neuroscience, in this week’s Journal of Neuroscience, scientists used functional magnetic resonance imaging to decode and reconstruct the perception of color within the visual cortex, specifically area V4. I’m not sure of the functional significance of the front cover illustration, but perhaps someone more versed in the visual system will tell. It reminds me of the color wheel posted on the blackboard in art class, illustrating that various perceived colors such as maroon, aquamarine, and even macaroni n’ cheese are simply synthesized from primary (blue, red, yellow) and secondary (green, purple, orange) colors.

It's the color wheel!
