Meeting the Needs of the Individual Learner: Brain-Based Learning (Day 3) Archdiocese of Dubuque Educators
To do for Session 3: Wednesday, November 19, 2014
Temporal Lobe
With your partner… review, clarify, check your understanding. How do we know what we know? What do you recall about each brain area? What questions come to mind?
The Brain in the News
A test of your memory: What do you remember…? Why did you remember…?

The Human Brain
The Reptilian Brain The Mammalian Brain The Thinking Brain The Triune Brain
How the Brain Works
Tan’s Brain
How do we know what we know?
f.M.R.I. Functional Magnetic Resonance Imaging
The Brain Stem Controls unconscious functions of the body; Heartbeat, Respiration
The Amygdala The brain’s “emotional sentry”: Scans all incoming stimuli for emotional significance
Incoming Signal Amygdala Thalamus Neocortex
The Hippocampus Aids in the formation of new memories - Transfers information from working memory to long-term memory H.M.
The Thalamus The brain’s “relay station”: Scans incoming stimuli & sends it on to the appropriate lobe for processing
The Hypothalamus The brain’s “thermostat”: Regulates hunger, thirst, blood pressure, body temperature & sex drive
The Corpus Callosum A massive band of nerve fibers, (200+ million) that connects the two hemispheres, relaying information between them
The Neocortex The outer ¼” of the brain’s surface; the “gray matter”; has 6 layers- is compact, yet has much surface area; it is the “thinking” part of the brain
Brainstem
The basic functional unit of the nervous system; We are born with, and retain throughout our lives, approximately 100 billion neurons; 30,000 fit on the head of a pin The Neuron
Every thought that you think… Every action that you take… Is the result of neurons communicating with each other! Google Image Source:
Has a nucleus which contains DNA, chromosomes, and other genetic material The Cell Body
The fiber extension from the cell body that carries an electrical impulse (action potential); Most are very short (less than one mm); Others can be up to one meter in length The Axon
Also called axon “bulbs”; located at ends of axon branches; Hold “pockets” that contain neurotransmitters for dispersal upon stimulation The Axon Terminals
The fatty, waxy coating that forms around each axon; made of glial cells; protects and insulates the axon; speeds the electrical impulse; Myelination follows a preset developmental pattern- from birth to about age 25 or 30 The Myelin Sheath
Strand-like fibers that extend from the cell body; They contain receptor sites for receiving neurotransmitters from other neurons; Dendrites grow and branch throughout our lives, depending upon experience and environment The Dendrites
Experience changes the physiology of the brain!
Learning is the act of making… and strengthening… connections between neurons!
It’s time for a quiz! Google Image Source:
