If You Are A Carrier Of A Particular Set Of Genes, Your Probability Of Committing A Violent Crime Goes Up By Eight Hundred And Eighty-two Percent.

We Don't Really Understand Most Of What's Happening In The Cosmos. Is There Any Afterlife? Who Knows.

When A Male Vole Repeatedly Mates With A Female, A Hormone Called Vasopressin Is Released In His Brain. The Vasopressin Binds To Receptors In A Part Of The Brain Called The Nucleus Accumbens, And The Binding Mediates A Pleasurable Feeling That Becomes Associated With That Female. This Locks In The Monogamy, Which Is Known As Pair-bonding. If You Block This Hormone, The Pair-bonding Goes Away.

When One Part Of The Brain Makes A Choice, Other Parts Can Quickly Invent A Story To Explain Why. If You Show The Command "walk" To The Right Hemisphere (the One Without Language), The Patient Will Get Up And Start Walking. If You Stop Him And Ask Why He's Leaving, His Left Hemisphere, Cooking Up An Answer, Will Say Something Like "i Was Going To Get A Drink Of Water."
