The human brain is composed of 100 billion nerve cells and 1000 trillion connections between those cells. It controls our emotions, which include happiness, surprise, fear, sadness, disgust, and anger. Emotions can sometimes be dangerous if they become extreme or if we don't control them well. The brain also handles memory through both short-term and long-term memory. It has incredible powers of perception and pattern recognition, as demonstrated through visual illusions.
