O is for Occipital Lobe

Day 114 of 365: Not only LookingSmug likes to geek out once in a while. I studied Human Factors Psychology and one of the toughest but also most enjoyable classes was on the physiology of the brain. The occipital lobe should be of primary interest to you flickrites, seeing as it is the visual processing center of the brain, and well, without it you wouldn't be seeing this now.


It's the bright part at the rear end. Each visual cortex (on either side of the brain) receives raw sensory information from the outside half of the retina on the same side of the head and from the inside half of the retina on the other side of the head. The brain then does the amazing feature of assembling these raw stimuli into a stereoscopic image.


Shmobist info: speedlight at 1/64 in front at subject's 11 o'clock and x-ray tube to the side.


tV: inspired by the letter O (not kidding, I thought of words for the letter O and Occipital Lobe was the first one that popped into my head - don't ask why) and LookingSmug's science project.


The More You Know™: The brain doesn't show up in a regular x-ray, so this image must be from some kind of CT scan.
