Under the MRI

Image
The MRI or the magnetic resonance imaging technique is probably one of the best modern day scientific inventions. this non invasive procedure has allowed us to peer into the human body and enhanced our understanding of ourselves. 
After my recent post on Sex under the MRI and the fascinating images the machine produced, I got to fishing outs some other fun stuff captured by this incredible machine.  Here's what I found! 



Fruits and Vegs
Captured by Andy Ellison, these images are a result of mere curiosity and fascination of how fruits, vegetables and flowers look under the MRI. I stumbled upon these images at petapixel.com, and the internet hound that I am, I sniffed my way to Andy's homepage, and I was absolutely blown away. Here are a few images of what I saw but I highly recommend you go and check them out for yourself. (Dont forget to check out his older posts.)

No more monkeying!

Optogenetics is a method of probing neural circuits with the help of a combination of genetics and optics. In this method light-sensitive genes from microbial organisms are used along with light in order to receive a response from neurons. This is a very amusing method which is proving to be very helpful and a recent study has added a whole new dimension to this method of altering neural activities.
The study used optogenetics and showed that the behaviour of monkeys can be altered using pulses of blue light which is known to activate specific brain cells. This result has provided the inspiration to develop a similar therapy for human beings. Previously this type of study was done on rodents and invertebrates but the result derived from the reaction in the brain of monkeys proved more helpful. The validation of the result was done with the use of an MRI and tests focussing on neurons responsible for specific eye movements. Both brain activity and subtle alteration in the eye movements …
