I was listening to a TV interview about Mind Map stuffs, and start to search materials related to human brain. It is interesting to know how does brain work, and how to use our brain effectively.
I found a couple of interesting brain tests and games from Cognitive labs. Testing your reaction, memory, brain ageing etc. It is fun. And I am certainly not happy with my own poor score 🙁 OMG. I need more trainings to improve my score.
Have fun. The tests are here
In addition, here is an article about the Mysteries of the Human Brain.
