For those of you who don’t believe there is beauty in science. This is a dissociated hippocampal neuron with an antibody stain against MAP2, a common cell body and dendritic marker. Billions of these guys make up the human brain through trillions of synaptic connections. Neurons really are beautiful.

This image shows details of the spinal cord. Cajal’s patient investigation revealed the elaborate organization of the fibers that course between the spine and brain. The top image is a lateral view of the spinal cord; along the left, motor nerves connect to muscles, and along the right, a sensory nerve (red) snakes down to the skin.
The bottom image is a cross section showing motor cells (black) in the spinal cord.

Erin Kaltenbrun, University North Carolina, Chapel Hill, and MBL Embryology CourseE10.5 mouse embryo antibody stained for neuronal cells and nuclei. Whole mount antibody staining using antibodies for neuronal cells (TuJi) and nuclei (DAPI), imaged through the dorsal posterior neural tube.
An image of a nerve impulse moving (conduction) along an axon. The membrane potential is the result of the distribution of ions across the cell membrane and the permeability of the membrane to these ions.

La Brain en Rose 3 is gallery of brain cells and structures, inspired by the work done a few years ago by some Harvard and MIT researchers with mouse brain cells (you can google “Brainbows” for lots more information). In warm, deep shades of pink, rose and magenta with white accents. Click through for more info and other paintings.
