THE BRAIN IS AMAZING The brain is adaptable, dynamic & ever evolving The brain is self organizing The brain translates environmental stimuli & formulates an action/reaction The brain forms patterns as a method to allow for higher order thinking & metacognition Neuroscience is an important foundation of education and occupational therapy We don’t really understand the function of the brain and how it supports occupational engagement and learning but we do know that brain structure and function changes as a result of engagement and learning.
BRAIN ANATOMY It weighs about 3 pounds. It is made up of 78% water, 10% fat, 8% protein, 1% carbs, 1% salt, and 2% other constituents. It has over 100 billion neurons. The brain stem is the oldest part of the brain (according to evolution science). The cerebellum controls movement. The cerebral cortex is thought to be the “newest” part of the brain and it allows adaptation from environmental stimuli. http://www.youtube.com/watch?v=HVGlfcP3ATI&fe ature=fvw
The Penn Field Mapillustrates thedifferentiation andspecialization ofbrain structure andfunction.
Nerve impulse Electrical charges flow up to the dendrite Charges accumulate at cell body Charges fill up to overflow cell body & fires Charge heads toward axonTravel is quick! Between 12 and 248 mph
WHAT DO YOU THINK MIGHT HAPPEN IF A PERSON WERETO HAVE DAMAGE TO NEURONS, LOBES ORHEMISPHERES?Would they? A. Experience a major loss of function. B. Be unable to learn new information. C. Require assistance to accomplish daily tasks. D. Adapt and areas of the brain previously designated for one function take over for another.

BRAIN TRUTHS Brains are flexible Brains respond to information from the environment Brains adapt to errors Brains integrates knowledge Brains have awareness and a sense of self Brains change with learning that occurs throughout development
HOW MIGHT THESE BRAIN TRUTHS IMPACTYOUR TEACHING? “Merzenich argues that practicing a new skill, under the right conditions, can change hundreds of millions and possibly billions of the connections between the nerve cells in our brain maps” (Doidge, 2007, p. 47) Bobby McFerrin hacks the brain with music: http://www.ted.com/talks/lang/eng/bobby_mcferrin_hack s_your_brain_with_music.html We hack brains with sound teaching methodologies 2.0 technologies.
NEUROPLASTICITY Neuroplasticity is the process by which the brain and nervous system produce morphological changes in response to environmental stimuli. Brain change affects us as well as our students: http://www.ted.com/index.php/talks/gregory_petsko _on_the_coming_neurological_epidemic.html
Use it or loose it appliesto our brain as well as our bodies!
NEUROPLASTICITY Positive Negative Neuroplasticity: Neuroplasticity: Increases cognitive Decreases cognitive reserve and promotes reserve and inhibits neural connection neuronal connections Mental Stimulation Non-stimulating Intellectual Pursuits Activities Social Interaction Social Isolation Good Emotional Health Poor Emotional Health Physical Exercise Sedentary Lifestyle Proper Nutrition Inadequate Nutrition Good Sleep Inadequate Sleep Substance Abuse
TAKE HOME MESSAGES Use it or lose it The brain is resourceful Plasticity is competitive Bad habits die hard Practice = Proficiency and Precision New activities requires lots of brain Avoid multitasking
