ANECDOTE

UK Biobank Brain Imaging

  • Ainslie Johnston visited a UK Biobank brain imaging lab, where 100,000 people's brains are being scanned.
  • Participants do cognitive tests during MRI scans, including a snap game to measure decision-making.
INSIGHT

Human Intelligence is Complex

  • Human intelligence is complex and not localized to a single brain area.
  • Larger brains and specific communication patterns correlate with higher intelligence, but much remains unexplained.
INSIGHT

Nerve Cell Communication

  • Nerve cells transmit information through electrical pulses, similar to Morse code.
  • This digital yes-no firing pattern is key for information processing.
