Forget computers, the human brain is the most complex machine that has ever existed, at least in the history of our planet. So much of it is still largely a mystery to neuroscientists.

Fascination with how our brains work has grown in recent years, so much so that last year the Obama administration proposed the Brain Activity Map Project, a bold research initiative intended to map the activity of every neuron in the human brain.

As you will see in the infographic below, that’s a lot of mapping. But how does that complex instrument of ours relate to the day-to-day stimuli that we encounter? Glad you asked. Here’s just a taste of how the brain interacts with environmental stimuli.
