My Brain on MRI
In this transverse slice, the 'front end' of my visual system is easily seen; the high-resolution image shows the eyelens, the extraocular muscles and the optic nerves leading to the optic chiasm. My eyes were closed during the scan, so my eyelids are also visible on this image. By convention, MRI images are displayed as though viewed from the brainstem, so the obvious cortical asymmetry actually shows my "left brain" sqeezing my
"right brain" out.
This midsaggital view is a slice between my right and left cerebral hemispheres, and shows the complex folds in the cortex. The corpus callosum (the major connection between the left and right hemispheres) is visible near the center of the image. The midbrain, pons, and medulla lead down to the spinal cord leading away from the brain. The primitive cerebellum, responsible for initiating and coordinating motor movements, is seen to the right of the medulla and pons. It is possible to identify the frontal, parietal, and occipital lobes in the midsaggital view. The temporal lobes lie at the sides of the brain, and are not visible in this view.
