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.
Brain aneurysm treatment. Coloured angiogram (blood vessel X-ray), in frontal view, of the head of a 49-year-old patient undergoing treatment for a brain aneurysm. A brain aneurysm is a dangerous swelling in a brain blood vessel. This treatment involves inserting metallic coils (black, centre) into the aneurysm. The X-ray is used to show the position of the coils, placed by electromagnetic controls, and a contrast medium shows the blood vessels (red). The coils cause clotting of blood in the aneurysm, and eventually the blood vessel reforms its wall. This technique is an alternative to direct surgery. The blood vessel being treated here is the basilar artery that supplies the base of the brain.
A midline section of the head and neck, displaying the elements of the brain and its extension into the spinal cord. The oral and nasal cavities and the palate and tongue are shown in relationship to the pharynx, larynx and esophagus.
