The Power of Metaphor

Does a dirty scoundrel need a bath or a moral lesson? Our brains easily confuse metaphor for reality, often with dangerous consequences, says Stanford biology professor Robert Sapolsky.

Jonathan Haidt, of the University of Virginia, has shown how viscera and emotion often drive our decisionmaking, with conscious cognition mopping up afterward, trying to come up with rationalizations for that gut decision. The viscera that can influence moral decisionmaking and the brain’s confusion about the literalness of symbols can have enormous consequences. Part of the emotional contagion of the genocide of Tutsis in Rwanda arose from the fact that when militant Hutu propagandists called for the eradication of the Tutsi, they iconically referred to them as "cockroaches." Get someone to the point where his insula activates at the mention of an entire people, and he’s primed to join the bloodletting.

Why is 18 the age of adulthood if the brain can take 30 years to mature?

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.

Mind & Brain
  • Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
  • Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
  • The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.

Believe in soulmates? You're more likely to 'ghost' romantic partners.

Does believing in true love make people act like jerks?

  • Growth-oriented people (who think relationships are made, not born) do not appreciate it.
  • Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.

Mini-brains attach to spinal cord and twitch muscles

A new method of growing mini-brains produces some startling results.

(Lancaster, et al)
Surprising Science
  • Researchers find a new and inexpensive way to keep organoids growing for a year.
  • Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
  • The mini-brains took control of muscles connected to the spinal cords.
