As a
microbiology, immunology, and molecular genetics student, fluorescent labeling
techniques are not something completely foreign to me. The Brainbow pictures however were
unlike any microscopy I had ever seen. The structure of neural pathways gave
these images a unique and beautiful order that I cannot imagine being matched
by histological analysis of any other bodily system. Because of the
complexities of the brain and nervous system, I thought other ways of imaging
it must also produce amazing results. My search turned up several other brain
visualization techniques known as diffusion magnetic resonance imaging (dMRI),
cerebral angiograms, and immunohistochemistry.
Immunohistochemical analysis of a human brain
Immunohistochemistry
is actually a widely applicable technique that is used to look at various
different body tissues. It
involves the use of fluorescent antibodies that are targeted to and tag surface
proteins to produce a picture. Cerebral angiograms are a little different in
that they look at the blood vessels of the brain rather than the brain
itself. This technology has
medical applications in that it can be used to detect problems such as
aneurisms. The dMRI process
depends on the diffusion of water molecules, and reflects their movement in
vivo. As the water interacts with
objects such as your neurons, the dMRI can pick up on this to produce an image.

The
multitude of technologies used to look at the nervous system and the beautiful
images all have their different clinical advantages and drawbacks. But their widespread use shows the
importance of imaging technology for medical professionals to deal with the
brain. Physicians need these
pictures in order to effectively assess a situation. Researchers need them in their experiments. Photographs are an art form closely
intertwined to the success of
neurology, both for scientists and doctors alike.

I really enjoyed your take on this blog assignment. The different types of brain imaging available was not a topic I was familiar with and I found it interesting to compare the varying pictures that they created based on what they were looking for. Aesthetically, the pictures are beautiful and without the prior knowledge that these were photos of the brain, I may have assumed they were art pieces. I can see how so many artists are inspired by neurology.
ReplyDeleteWhen I see the digital images created by medical machines that recreate brain images and the brain's neural activity I have always thought they could possibly be artistic. I thought they often could be ink blotches that are visually stimulating and makes the mind work to categorize what is it currently seeing even though it is the brain's activity being shown. I must agree with Madison, the images created by these machines can easily inspire an artist to transform certain aspects of the brain into masterpieces.
ReplyDeleteWow those are all very cool. I like the one with the blood vessels the best, they look like tributaries flowing into a river or lightning coming from a tesla coil. Also I believe something similar to the dMRI image is currently displayed on the login page for myucla.edu!
