Brain Development
Simple Cell Message comes in Information
processed Message goes out

Brain Development
A cell can connect with other cells
Over 100 billion brain cells
Each cell can develop over 50,000 connections
Result is trillions of paths
![Page 5: The Impact Trauma and Stress Can Have on Healthy Brain Development Gene Griffin, J.D., Ph.D. School Mental Health Conference June 27, 2012.](https://reader036.fdocuments.net/reader036/viewer/2022070400/56649e405503460f94b31f36/html5/thumbnails/5.jpg)
Brain Development
Those connections that are used frequently become stronger (networks, highways)
Those cells that never connect to others die off (pruning)

Brain Development
Critical Periods Timing Matters For some brain functions, there
is a particular time when that function should develop
If the timing is off, that function may be delayed or never develop

Brain Development
Plasticity Your brain changes based on what it is
exposed to Events cause changes in the brain We strengthen connections through repetition Powerful events can cause major changes There is always hope for change

The Brain controls many functions Physical (Breathing, heart rate, body temperature) Emotional (Love, Hate, Fear, Calm) Cognitive (Language, Math, Planning, Impulse
Control) The functions are affected by the sequence of
the brain development, with physical development ahead of emotional and cognitive development

Brain Development- Adolescents

Teenage Development
Adolescence is like giving a teenager a car with A new body with a lot of horsepower
(physical); A sensitive gas pedal that can go from 0 –
60 mph in a few seconds (emotional); and A brake system and steering that won’t
work effectively for several years (cognitive);

Trauma’s Impact on the Brain
Disruption in Neural Development can include: Failure to expose youth to appropriate
experiences at the critical times (Neglect) Overwhelming the brain’s alarm system
(Abuse)

Alarm System as a Survival Mechanism
Extreme or frequent threats can damage the alarm system
With trauma, the alarm system is too easily triggered and too slow to shut down
