Dr. Willis concludes that there are three main brain systems she refers to as RAD which are the keys to building better brains.
RAD is short for:
R: Reticular Activating System (RAS)
A: Amygdala
D: Dopamine
Reticular Activating System
The RAS is the attention activation switching system located at the brainstem. You can
control where students’ focus goes in the classroom, and what information gets through the RAS by incorporating novelty, multi-sensory learning, goal-motivated attention, and creativity with learning activities.
Amygdala
The amygdala is the center of the brain’s emotion relays in the limbic system and it also strengthens the long-term memory potential of information that enters accompanied by positive emotion. With low-risk, low-stress, positive learning activities, the RAS and amygdala can help
the brain focus on the sensory information of the learning activity.
Dopamine
Dopamine is one of the brain’s most important neurotransmitters, proteins that carry information across spaces between nerve endings. When you can incorporate pleasurable learning experiences and activities into lessons, the dopamine released is then available to increase pleasure, attention, and memory.
Judy Willis Will be delivering seminars in Argentina "Learning and the Brain Conference" Sept 4-5, 2009.
