Studying for boards is no fun at all, but finding stupid neuro trivia = score 1 for t3h win!
Here's some stuff from Rolak's Neurology Secrets (4th ed):
What are the most common movements seen in dead people?
The Lazarus sign is a quick flexion of both arms up over the chest, beneath the chin, observed in brain-dead patients. It may represent spontaneous firing of hypoxic cervical spinal cord neurons.
If you place a human skull on the ground and begin piling weight on top of it, how much weight can be added before it cracks?
If the weight is applied slowly, the human skull can support 3 tons.
What is the softest sound that can be detected by the human ear?
The decibel scale is set at 0 for the softest audible sound, which represents vibratory energy striking the eardrum at an intensity of 0.0002 Dy/cm^2, which is a range of vibration scarcely larger than the width of several atoms.
What is the smallest amount of light the human eye can detect?
The human eye has 125 million rods, each one containing 1000-folds in its photoreceptor membrane, with each fold containing 1 million molecules of photoreceptor. This extraordinary light sensing array can detect one single photon, which is 10^-11 watts.
Pretty cool, no?
PS: U-Texas Med has an *awesome* site for first-year Gross Anatomy -- they even have high-resolution plates of Netter's atlas online, which is rather odd, since these plates usually retail for like ~200$ online o_O
