That blue is gorgeous.
I apologize for the lack of real posts recently. With school starting, I’ve been busy getting into classes and involvement. Once I’ve got everything together, expect more in-depth posts and fewer reblogs. Until then, feel free to message me about anything!

Retinal ganglion cells transmit signals from the rods and cones in the eye to the brain. The retinal ganglion cells shown here have the extraordinary property that their dendrites all point in a single direction. Remarkably, these neurons respond best to objects moving in the direction that the cells “point.”
In this particular image, a mouse retina is seen with “J” retinal ganglion cells marked by the expression of a fluorescent protein. Of course, in real eyes it’s not that simple – the millions of other neurons that these are entangled with are not marked, and thus appear invisible. The image was obtained with a confocal scanning microscope, and pseudocoloured.

cool hand angiography
An angiography is the imaging of blood vessels, usually by injecting a radio-opaque fluid into the veins and then x-raying them. This patient has a finger angioma, where a benign tumor has developed and resulted in an unusual clogging of vessels.
I think my favorite part is the delicate delta of veins under the thumbnail though.
