Genes are rarely about inevitability, especially when it comes to humans, the brain, or behavior. They're about vulnerability, propensities, tendencies. — Robert M. Sapolsky Copy Share Image
Genes are important for understanding our behavior. Incredibly important - after all, they code for every protein pertinent to brain function, endocrinology,… — Robert M. Sapolsky Copy Share Image
“The brain is heavily influenced by genes. But from birth through young adulthood, the part of the human brain that most defines… — Robert M. Sapolsky Copy Share Image
The regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes. — Robert M. Sapolsky Copy Share Image
Almost always, genes are about potentials and vulnerabilities rather than about determinism. — Robert M. Sapolsky Copy Share Image
“Secure-attachment 7Rs show more generosity than average. Thus 7R has something to do with generosity—but its effect is entirely context dependent.” — Robert M. Sapolsky Copy Share Image

“pain makes aggressive people more aggressive, while doing the opposite to unaggressive individuals.” — Robert M. Sapolsky Copy Share Image
“Thus, for our purposes, genes aren’t about inevitability. Instead they’re about context-dependent tendencies, propensities, potentials, and vulnerabilities. All embedded in the fabric of the… — Robert M. Sapolsky Copy Share Image
“If we accept that there will always be sides, it’s a nontrivial to-do list item to always be on the side of angels. Distrust… — Robert M. Sapolsky Copy Share Image
“In other words, the more genomically complex the organism, the larger the percentage of the genome devoted to gene regulation by the environment.” — Robert M. Sapolsky Copy Share Image
“The subject of one experiment is a rat that receives mild electric shocks (roughly equivalent to the static shock you might get from scuffing… — Robert M. Sapolsky Copy Share Image
“No brain region is an island, and the formation of circuits connecting far-flung brain regions is crucial—how else can the frontal cortex use its… — Robert M. Sapolsky Copy Share Image
“We process emotionally salient information more rapidly and automatically, but with less accuracy. Frontal function—working memory, impulse control, executive decision making, risk assessment, and… — Robert M. Sapolsky Copy Share Image
“Most broadly, the PFC chooses between conflicting options—Coke or Pepsi; blurting out what you really think or restraining yourself; pulling the trigger or not.… — Robert M. Sapolsky Copy Share Image
