Some Unique Brain Facts
1. The brain feels similar to tofu, and contains
enough fluid to fill a 1.5-2 litre soda bottle.
2. Archaeological evidence suggests that human
brains may have shrunk over time. However, there is nothing to show that humans
are less intelligent today compared to previous times.
3. The brain alone consumes about 20% of the oxygen
in our blood, and 25% of the glucose. Thus it is a major energy consumer.
4. The human brain has more pronounced wrinkles
than the brains of other species. This is linked to more sophisticated neural
pathways and higher intellectual functioning.
5. Neurons only make up 10% of our brain cells. The
rest is glue holding the neurons together. These other cells also mop up excess
neurotransmitters, provide immune protection, and regulate synapse growth and
functioning.
6. The brain doesn’t fully mature until we’re in
our late teens. Multitasking, empathy and good decision-making are some of the
last skills to develop.
7. The brain never stops changing. It can adapt to
damaged nerves, grow new neurons, and form new neural connections.
8. Male and female hormones lead to differences in
male and female brain development. For example, brain imaging has revealed
general differences in the way both sexes experience, make social decisions and
manage stress. However, nurture and environment play an important role as well.
