Talk:Samer Hattar

Doesn't the upper arrow point in the wrong direction?

Light enters the eye and hits the retinal pigmented epithelium (maroon). This excites rods (grey) and cones (blue/red). These cells synapse onto bipolar cells (pink), which stimulate ipRGCs (green) and RGCs (orange). Both RGCs and ipRGCs transmit information to the brain through the optic nerve. Furthermore, light can directly stimulate the ipRGCs through its melanopsin photopigment. The ipRGCs uniquely project to the superchiasmatic nucleus, allowing the organism to entrain to light-dark cycles.

"Light enters the eye and hits the retinal pigmented epithelium (maroon)," it says.

I think this text is correct and the image shows light coming from the wrong direction. Am I right?

I know it's confusing, but no, light comes from that direction, through the cells, hits the pigmented epithelium, and starts the signal cascade. Search for "retina anatomy" if you're interested.

Proposed merge with Chronobiology article

It is proposed that much of the Scientific work section be merged (or moved) to the Chronobiology article. This section has more to do with the details of chronobiology than with the person in this article. After a merge or move, this article could be reduced in size to refer to Hattar's contributions to chronobiology with a main article reference to Chronobiology for details.
