Today, more things that emit light are placed on the streets and in every buildings and in front of us (e.g. my Surface RT) for a purpose. What's more have we learned about effects of light on our body/health. The eyes detect light with some photoreceptors allowing us to see things. Besides, we may sense light without seeing and this is a thing.

Do we have those photoreceptors that are not for seeing things (non-visual ones)?? Yes, there are some in the eyes. And the thing is some also found in the brain. Not sure if they work though. Those things seem to function (i.e. to detect light) in the brain of birds, frogs, and fish. What they have to do with the body systems remains mystery.

My past work?? Say this review. I documented the location of those photoreceptors in the fish brain (organized in a map). Currently known ones. Those things are present in brain areas that seem to respond to light/dark. Also, they may communicate with major chemical systems in the fish brain that are similar among animals. So, those photoreceptors are quite important.

What each of those photoreceptors does in the brain that controls body and behaviors of fish (e.g. maybe the timing fish develop/mature or spawn eggs, or the pattern fish sleep/move or respond to things) is next. We also hope to learn about those things in other animals.

Okay,  I wrote the first piece of Neuro ThingS. Also have a little warm-up for upcoming job interview. It's time for me to fly overseas soon (maybe get to try Pokémon Go). First,  prepare to 'catch' the job!!
