“If We Understand the Brain,We can influence it”
Gerry CharleboisExecutive Director of Advanced Academics
Carrollton Farmers Branch [email protected]
Goals for Brain Based Teaching
To better understand how the brain/mind works and to explore the implications of the research for:
• You personally - your own learning• Your students – how they learn and what
you can do to increase their understanding and ability to use information.
• Your teaching – how you structure your classroom and instructional activities.
Brain Quiz1. T F We use only 10% of our brain.
2. T F For a higher level cognitive activity one uses many areas of the brain.
3. T F Complex music produces complex brain activity.
4. T F There is one specific area for arithmetic and other content areas.
5. T F Development of knowledge occurs in a ladder-like fashion.
6. T F We can grow new brain cells.7. T F Teens' brains are like a toddler's brain.8. T F Food influences our brains.9. T F Learning through repetition produces a
permanent neurophysiologic change in our brains.
10. T F Gifted teens have more developed brain maturation in the frontal lobes.

Physical Structure of the Brain
• Cerebrum (Latin for brain) Cortex (Latin for bark)
• Mid Brain – the CEO of the nervous system (Includes thalamus, hypothalamus, amygdala, and hippocampus) – responsible for emotional functions, memory, social bonding, intuition, immunity, and healing. Sensory information passes through the thalamus before entering the cerebral cortex.
Physical Structure of the Brain• Frontal Lobes – (last to mature, develop fully) controls
consciousness, critical thinking, the ability to problem solve, plan for the future, and expressive speech.
• Parietal Lobes – (interprets where pain is coming from) receives and processes data from the senses, responsible for touch, pain, temperature, calculating, and writing.
• Occipital Lobes – (vision center) controls processing of visual images, hearing, and language
• Temporal Lobes – ( memory & who we are as an individual) interprets music and language, stores information
Brain Development
Development occurs in levels with periods of discontinuity in skill and brain organization
Occurs in clusters with emergence of a new capacity (new capacities emerge in teens and early adulthood)
In new learning, a person moves down repeatedly to low levels in order to build components to produce new high-level skills.
Neurons grow all the time - they are affected by the environment and our experiences. Cyclical growth - revisiting, relearning, explains the flexibility and plasticity of the human brain
Frontal cortex is central - leading the growthIs strongly connected to the limbic system (emotions and memory) Both interact constantly
Development continues…
Three Parts to our Brain:
Genetic wiring – highly inheritable
Environment – in our surroundings with no
conscious reactions : nutrition, drugs,
toxins, temperature
Experience – in our surroundings with
conscious reactions: people, tv, computers,
books, museums, etc.
We are whole brained!
• The brain lights up all over when we are working on varied processes
• Intelligent people use multiple areas• The more efficient the brain-task, the more
defined the area of the brain• Cross hemispheric connections
The Learning Process
The brain is continuously trying to make sense out of its world – what is meaningful in what it experiences.
The brain is a pattern making machine…
The brain becomes primed with familiar patterns (rituals)
and aroused by unfamiliar ones (novelty).”
How the Brain Learns:
The Brain takes these ‘associations’ and forms them into patterns. It is the brain’s way of making sense of the world. These patterns form the basis of all human understanding.

We are biologically designed to solve problems and we are
happiest when we are solving them successfully.
Human beings are designed to be fulfilled.
Challenge
• The brain functions at its peak when appropriately challenged.
• Challenge engages both sides of the brain: evokes intimate communication between hemispheres.
• The way to educate the whole brain is to challenge it.
• A little bit of tension improves learning.• Verbal & analytical tasks engage the high
functional abilities of the right hemisphere.• Abstract concepts & underlying principles pulls
the two hemispheres together.
Challenge
• When the task is too hard – the whole brain wakes up.
• When it is too easy – the brain falls asleep (spacing out).
• No learning can take place when the brain is underactivated.
• The profoundly gifted rarely have difficult enough tasks to fully engage their brains.

“All thinking has feeling. Emotions shape cognition.
There is no learning without emotional engagement.”
How the Brain LearnsEmotions act as ‘functional organizers.’ They move us. Biologically and at the most
fundamental level they serve as an ‘approach’/
’avoidance’ mechanism.

Inside the Teenage Brain
~ Around puberty, the brain blossoms with new brain cells
~ Frontal lobes undergo wholesale renovation extraneous neuronal branching gets ‘pruned’ back
~ Also occurs in infancy for a more efficient, consolidate circuits
~ Teens’ rational, thoughtful frontal lobes “light up” less their amygdala lights up more!!
~ Teens process information differently than adults; very emotional
~ Mid Brain processing daily info and interactions
Adolescence as Autonomy and Identity
A New Psychosocial Stage....Belonging vs. Rejection•self strongly defined by group•self defined through others’ eyes•sense of belonging essential to well being•hyper vigilance about being liked and accepted•great conflicts over divergent opinions of significant people; avoidance of anger, confrontation, and differentiation•identity, collective and interpersonal, humorously referred to as ‘we-go’ instead of ego
Biographical paths and self transformations•recursive nature, not ladder-like•every time we move forward, we always pull something from our early development.Embedded Identity• less focus on autonomy, separation, differentiation• more focus on connection, culture, relationships
Adolescence
Neuroscience of Intelligence
• Research in neurogenesis has changed idea of intelligence as a fixed trait to a set of capacities that are shaped throughout life as neurons are born and dendritic connections are made
• Intelligence is the ability to catch on, to make sense of things, and to know what to do about it
• Rich complex experiences, access to intellectual resources, good nutrition, and low stress builds neuronal connections
• Gifted people – evidence of enhanced interconnectivity and frontal connectivity
AHA! Moment
• A split second just prior to an AHA! moment - all the senses shut off and all the energy is focused
• Burst of gamma electricity, high energy, dopamine rush!
• Flow is sustained attention & continuous AHA! Experiences
• Flow comes easily to creative adolescents
The Gifted Brain
• The brain expansion during childhood – cortex and axon branching & myelination in frontal lobes – relatively earlier with gifted children
• Gifted brain exhibit superior neurophysiology in frontal areas – greater density of localization of neurons & thickness of cortical layers in frontal areas
• Some studies show gifted brains have double the number of gliocytes than the normal brain
• Gifted males’ brains shut down verbal to do spatial task• Connectivity must be robust to do difficult cognitive
activitiesNext decade: Functional Connectivity
Recommendations for Gifted Adolescents
• Monitor attention and learn mindfulness – pay attention to the present moment
• Use nutrition, exercise, sunlight, sleep to manage your mood
• Know your personality and mood styles so you can use them to your benefit rather than being controlled by them
• Visualization, go to your flow
Deep learning comes through a sequence of:
• Experiences – reading, lecture, gathering information
• Reflection – think of the idea, write the meaning in their own words; making meaning
• Abstraction – develop a theory, apply to different area; creating new ideas
• Active testing – share your information, presentation; generating new experience
The learner is in control.
Stressed
(Some white showing below iris)
When the white is showing between the iris and the lower lid in both eyes, it indicates mental or emotional stress and possible fearful feeling or worry. If there is more white showing in your left eye, the stress is about concerns in your personal life. If there as more white showing in the right eye, the stressful thoughts or feeling are related to business, professional or financial factors.
Potentially Violent
(White shows above iris)
If you see someone with the white showing above the iris,
it indicates not only stress but also that the person may react in a violent manner.
For example, a person who is approaching the psychological fight-or-flight
threshold may have white showing above the iris.
Mental Disconnect
(White is showing all the way around the iris)
If you see someone with the white showing all the way around the iris, be careful. This indicates someone who may be in a state of extreme mental disconnect and may not even be aware of his actions. You will sometimes see this in a person who is going into shock after a catastrophic event or who is under influence of dangerous drugs.

Swimming to Antarcticais a thrilling, modest, vivid, and
inspiring account of a life of aspiration and
adventure.
Four points to remember:
a. learning is biological & active – mind/body/spirit
pattern drivenbrain is encased in a bodyexercise improves cognitive function
b. emotion increases learningc. eliminate threat d. deep learning comes through reflection
and active testing
As educators we are responsible for helping students ‘guide out’
from themselves the beliefs and behaviors that
promote optimal living.When we teach our students how
to learn, we are also teaching them how to be happy.
