Brain Facts: The human brain weighs about 3 pounds and is 75% water. It uses about 20% of the oxygen in the body. There are five kinds of brain waves, and the brain is influenced by chemicals known as neurotransmitters. The brain is very complex, but one of the Brain regions at Brainfacts.org is the prefrontal cortex which is responsible for executive functions.

The brain and emotions: the fight or flight response
The fight or flight response is a physiological and emotional response to danger, perceived threats, or stressful situations. The brain’s alarm system (the amygdala) instantly sends chemicals to signal the hypothalamus (command center) to immediately prepare with a rush of hormones (adrenaline, epinephrine, and cortisol). This triggers the acceleration of breath and heart rate and other physical responses, as well as emotional responses like anger or fear. This response helped our ancestors survive when facing wild animals and other dangers. In today’s world we rarely face life-or-death threats, but the same response can be triggered by social stressors like job interviews, public speaking, or arguments. This powerful reaction makes it difficult to access the thinking part of the brain (prefrontal cortex).
• Threat (perceived) triggers the brain’s alarm system
• Alarm system (amygdala) signals the Command center (hypothalamus)
• Rush of hormones immediately sent
• Generates changes in body
• Engages emotions
• Thinking (prefrontal cortex) is difficult
• First flush subsides in 6 seconds
• Flows through in 90 seconds
• Fades to normal in 20+ minutes
To manage emotions, PAUSE:
• Pause and notice: the physical cues in the body, the situation, your thoughts and emotions.
• Accept and reset: name the emotion, and calm the reaction with coping skills. The inital flooding subsides in 6 seconds, and flows through in 90 seconds.
• Uncover the drivers of your reaction, resist urges.
• Stop and step back: take a time out if possible. It takes 20+ minutes for the body to return to normal.
• Explore options and express empathy: when calmer, choose best actions, learn about the experience of others.
