OVERVIEW: As we look at the relationship of anger to the brain, it helps to have context. All parts of the brain inter-connect with all other parts – each structure & each chemical having multiple functions, doing different things in different locations. But greatly simplified, the brain has Left & Right side differences, & 3 major sections – Old, Middle & New. In reasonably healthy people, and under normal circumstances, rash impulses (Old) & emotions (Middle) are modified & managed by the ability to think things through (New).

1. RATIONAL THOUGHT is formed in the front part of the Neo (cerebral) cortex, the outermost layer of the brain, which integrates higher mental & instinctive functions, general movement & perception.
🔸 The Pre-frontal cortex (PFC) makes
up the largest part, the 2 lobes above & behind the eyes. It is the ‘seat’ of personality, & its main job is to equip us to process information (internal or external input), so we can decide how to use information located in other sensory & memory centers throughout the brain
• Together, the 2-part PFC is a high-level filter for emotional control, but each hemisphere does it differently. They gives us access to accumulated info that tells us how to communicate & interact appropriately in private or public situations. It allows us to take actions based on a specific goal in the moment, & does this in part by preventing irrelevant stimuli from interfering (we can keep reading a book even if there’s a lot of noise nearby….). It’s also the location for self-talk.

✿ The PFC carries out executive functions (higher-level mental processes that organize lower-level ones, to regulate & verify behaviors) TO:
• consider future consequences of current activities
• determine what’s unreal vs real, rational vs. irrational, appropriate or inappropriate… & filter right from wrong
• figure out conflicting thoughts (same-different / better-best / good-bad)
• have social ‘control’ (suppress urges leading to unacceptable outcomes)
• identify expectations based on actions (possible outcomes)
• make sound judgments & work toward a defined goals
• plan responses to complex or difficult problems
process current environment & past memories (See “Brain anatomy”)
There are 3 main models for how the brain works, & combining them gives the most accurate picture. They are:
Hierarchy: some things must happen before others can work. The brain’s lower levels must be working for the higher ones to run correctly.
Value systems: some things are more important than others
Synchronization: what’s happening or not happening all together at any given moment has a big impact on the brain
🔸 According to “The Life Model”, the brain’s right hemisphere has a 4-level emotional regulation control center** (similar to DNA & processor chips). It keeps the activity of the brain running smoothly as long as emotions do not become more intense than the system can handle
** CENTER functions needed to be human include 19 essential & nonverbal skills that can be learned & passed on from one control center to another….. We like the people with these control center skills and generally avoid people who lack them (MORE…..)
A healthy center is built on positive & joyful experiences with significant relationships, which gives a great capacity to cope with stress. When someone has had too many bad life experiences, the brain has a very limited capacity or skills to regulate & cope, & needs help to heal itself.
1. controls our personal reality – how we identify (name) our experiences
2. controls our basic evaluations – how we understand our experiences
3. regulates motivation for everything we do, & synchronizes our life rhythms, from the cingulate cortex
4. gives the ability to quiet ourselves – to not ‘lose it’, stay upset for too long, or over-react. Also, gives us our Identity, ‘Who I am’, from the PFC
