Question: How does the brain work.

Ed Bracey answered on 14 Nov 2017:

-Short answer, we don’t really know yet!
-Long answer, what we do know is, our brain is made of special cells called neurons.
They are special because they’re electrically active – they can switch other neurons on and off. And work together to form circuits, something like those you might find in a computer, except way, way more complicated.
-Everything you do, when you see, smell, hear, talk laugh, move, feel happy or sad, is because different circuits in your brain are getting switched on or off.
To get an idea of how complicated the problem is for neuroscientist, there are 86 billion neurons in a human brain. And each neuron can be connected to as many as 10,000 other neurons, pehrps more in some cases. So there are around 50-100 trillion connections in your mind! That’s more stars than there are in the galaxy! That means we’re all walking around with the most complicated things in the known universe inside our skulls!
