Hello, just a quick question , in the dark compared to being in the light, is there any change in Neural activity in the brain when in the dark compared to in the light?
With a complete absence of light, the process of visual phototransduction (http://en.wikipedia.org/wiki/Visual_phototransduction) does not occur - so there is less neural activity, but it's probably not overwhelmingly considerable. What's the application of this question if you don't mind me asking?
Thank you for your answer and the link. The question is related to another thread I have open about light and dark being a state of the mind.
(there are still changes in neural activity with decreasing light or a sudden complete darkness, otherwise we would just keep seeing what we last saw when the lights were on). Darkness seen is still a "state of mind", in the sense that vision is part of a sort of "virtual reality" that the brain somehow generates for itself. I think that more or less recently it has been concluded that vision has two main processing pathways, shades of light and dark, and separately, colors. Then it all somehow appear combined to us.
