  1. The human brain contains about 50 billion to 200 billion neurons(nobody knows how many for sure), each of which interfaces with 1,000 to 100,000 other neurons through 100 trillion (10 14) to 10 quadrillion (10 16) synaptic junctions. Each synapse possesses a variable firing threshold which is reduced as the neuron is repeatedly activated. If we assume that the firing threshold at each synapse can assume 256 distinguishable levels, and if we suppose that there are 20,000 shared synapses per neuron (10,000 per neuron), then the total information storage capacity of the synapses in the cortex would be of the order of 500 to 1,000 terabytes. (Of course, if the brain's

    storage of information takes place at a molecular level, then I would be afraid to hazard a guess regarding how many bytes can be stored in the brain. One estimate has placed it at about 3.6 X 10 19 bytes. About 32,000,000 terabytes)

  3. I've had sleep paralysis it really sucks, I was freaking out. It is also one of the prime causes of people believing they were abducted by aliens.

  5. I'm looking forward to using this site as a reference next time I tell a girl that they're more emotional than men and we think things out better.

  7. Whether this Ben Pridmore fellow is the "world champion of memorization" is merely the opinion of one organization that held a contest. 20/20 just did a special on "superhumans" and a man with Asperger's was able to memorize 22,000 digits of Pi in 5 hours. I find that far more impressive.

  9. I agree with Kat, Mr. Pridmore may be the fastest at memorizing the order of 52 things, but that doesn't mean he has the best memory.

  11. (More) intelligent people more often avoid artifical dye and preservatives. Point 9 is actually a ring closure.

  13. I recall ex basketball player Jerry Lucas had at one point memorized the entire NYC phone directory, and could prove it by having people ask him to recite, say, the 57th name on page 578! I saw him do this on the Tonight Show (with Carson, I believe) and he got them all correct. Personally, there is no way i could memorize even a single page of such basically random data.

  15. Neurons don't make up grey matter the cell body of the neuron does and the myelin coated axon makes up the white matter
