Shelley's Terminology for Exam 2 Flashcards
Darwin’s theory
Darwin taught us that learning is the survival mechanism we use to adapt to constantly changing environments
what has a significant bearing on a students academic performance
Learning, memory, concentration, and mood
PA presents a physiological stress to the brain that , when balanced with recovery…
… promotes adaptation, growth, preserves brain function & enables the brain to respond to future challenges (learns)
Brain is flexible - plastic -
an adaptable organ that can be molded by input
Synapse
Synapse - the junction between cell branches
Axon
Axon - the outgoing branch
Neurotransmitter
Neurotransmitter - carries the message across the synapse
Dendrite
Dendrite - the receiving branch
Glutamate - neurotransmitter -
stirs up activity
Gamma-aminobutyric acid (GABA) - neurotransmitter -
clamps down on activity
The more the connection is activated…_________
… the stronger the attraction becomes
Serotonin
Serotonin - influences mood, impulsivity, anger & aggressiveness
Norepinephrine
amplifies signals that influence attention, perception, motivation & arousal
Dopamine
learning reward (satisfaction), attention and movement
BDNF
Brain-derived neurotrophic factor
what does BDNF do in the body?
BDNF - builds and maintains the cell circuitry
what causes a synapses to swell?
Repeated activation, or practice, causes the synapses themselves to swell and make stronger connections
Exercise can help improve our _________by creating a _________ environment for learning
state of mind, conducive
Exercise also strengthens the cellular machinery of learning - during this time, what happens to the BDNF?
Exercise also strengthens the cellular machinery of learning - it increase the BDNF which in turn gives the synapses the tools they need to take in information, process it, associate it, remember it and put it into context.
Exercise improves learning on what three levels?
- It optimizes your mind-set to improve alertness, attention and motivation
- It prepares and encourages nerve cells to bind to one another
- It spurs the development of new nerve cells from stem cells in the hippocampus
The challenge that still exists - PA
- Which type of physical activity is best?
- How long do you have to move to have these benefits?
Your attention circuit in the brain is influence by the___________
emotion circuit
Emotion circuits are more easily activated by ___________
the negative
amygdala
Affects the interaction of emotion and attention
