Review of the ventricles of the brain using motion graphics with labels, brain sections, and MRIs. This was the author’s first video podcast, just after the video iPod hit the market in late 2006 & predicted that his would be a great aid to education!
(menos)
This is a discussion of midbrain lesions involving the oculomotor and trochlear nerves, and the descending motor and ascending sensory systems. The concept of brain stem crossed syndromes is discussed. A brain stem MRI is also presented.
