The human brain is incredibly complex, weighing in at around 3 pounds and consuming roughly 20% of the blood and oxygen in the body. There are many distinct parts of the brain, each one providing different physical, cognitive, and emotional functions. For example, the frontal lobe is responsible for concentration, attention, personality, expressive language such as speaking, and judgment. That is why an injury to this part of the brain may change your personality or ability to control emotions. Another example is the temporal lobe, which controls memory, hearing, and understanding language. Therefore, an injury to this part of the brain could impact memory and communication. The brain stem affects breathing, arousal, heart rate, and consciousness. A brain stem injury is extremely dangerous because it controls involuntary functions that are crucial for survival.
