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.
