Pawsitively Tuesday – Your Brain

Just three weeks after conception, the embryonic brain generates a quarter of a million neurons every minute.

About 20% of the body’s energy is channelled to the brain, yet it remains staggeringly efficient, consuming less energy than a filament light bulb.

The human brain isn’t fully developed until the mid-twenties – much later than experts once thought.

The internal clock that controls sleepiness runs up to three hours ‘late’ in teenagers, although scientists aren’t quite sure why.

Even into old age neurons are still building new connections and circuits, maintaining our ability to adapt and learn.

  1. Am always interested in the brain and appreciate your relevant tidbits of information! It is good to know that as we age into seniors we can still adapt and learn. So you can teach ” an old dog new tricks”…. 🙂


    • Peta,
      Of course we dogs have know far longer than the scientists that we can learn new tricks at ANY age. This is provided there are appropriate treats.
