reasons to apply neuroscience to the study of happiness - ANSWER✅✅- control for
biases and other problems (happiness is subjective)
- discover underlying neural mechanism of mood states
- provide means of evaluating treatment techniques
- provide evidence that mind changes --> brain changes (growth mindset)
growth mindset - ANSWER✅✅- people learn that their most basic abilities can be
developed through dedication and hard work
- creates love of learning and resilience that is essential
programs to develop growth mindset are most beneficial in students with
__________________ - ANSWER✅✅low socioeconomic status or who are
academically at risk
_____________(low income/high income) students are less likely to hold a growth
mindset - ANSWER✅✅low income
, _________(low income/high income) students who exhibit a growth mindset may
perform better than _________________(low income/high income) students with a
fixed mindset - ANSWER✅✅low income, high income
self-directed neuroplasticity - ANSWER✅✅- all mental activity creates new neural
structures
- every thought leaves an imprint
- repeatedly doing small things inside your mid over time will lead to bigger changes
in your brain and your experience of living
happiness and ________ has one of the strongest correlations - ANSWER✅✅social
support
the greatest predictor of happiness in college students during periods of high stress
is ___________ - ANSWER✅✅social support
how many pounds is your brain? - ANSWER✅✅3 lbs
how many neurons does the brain contain? - ANSWER✅✅86 billion neurons
how many synaptic connections does the average neuron make to other neurons? -
ANSWER✅✅1000 - but ranges from a handful up to 200,000 in Purkinje cells
what percent of the body's oxygen and glucose is used by the brain? -
ANSWER✅✅20%
T/F: your brain uses up to 10x more energy when you're thinking hard, rather than
in a deep sleep. - ANSWER✅✅False
levels of organization of nervous system:
cell: ___________
tissue: ____________
organ: ____________
system: ____________ - ANSWER✅✅- individual neurons
- nerves, ganglia
- brain and spinal cord
- nervous system
Cell body - ANSWER✅✅the cell's life support center
Dendrites - ANSWER✅✅receive messages from other cells
Axon - ANSWER✅✅passes messages away from the cell body to other neurons,
muscles, or glands
neural impulse (action potential) - ANSWER✅✅electrical signal traveling down the
axon
, myelin sheath - ANSWER✅✅covers the axon of some neurons and helps speed
neural impulses
terminal branches of axon - ANSWER✅✅form junctions with other cells
terminal button - ANSWER✅✅bud at the end of an axon; forms synapses with
other neurons; sends information to other neurons via neurotransmitters
Study on 3-5 year old children with higher use of screen-based media had
____________(higher/lower) measures of structural integrity and myelination and
scored _____________(higher/lower) - ANSWER✅✅lower, lower
axons have two basic electrical potentials - ANSWER✅✅-resting membrane
potential
-action potential
resting membrane potential - ANSWER✅✅- extracellular fluid: rich in Na+ and Cl-
- intracellular fluid: rich in K+
- banana(potassium) in the ocean(NaCl)
T/F: Action potential of a given neuron is an all or none phenomenon -
ANSWER✅✅True
How is an action potential determined? (yes or no) - ANSWER✅✅excitatory vs
inhibitory fighting over who is going to win to determine if the action potential will
fire
Synapse - ANSWER✅✅a junction between the terminal button of an axon and the
membrane (usually somatic or dendritic membrane) of another neuron
chemical transmission at the synapse - ANSWER✅✅-action potential reaches
terminal buttons
-triggers release of neurotransmitters
-flood into synapse
-can be received by receptors (dendrites) of other neuron, washed away, or drawn
back into terminal buttons via reuptake
Reuptake - ANSWER✅✅transporters located in the presynaptic membrane
transport the molecules of neurotransmitter back into the cytoplasm (most common)
How do SSRIs work? - ANSWER✅✅SSRIs block the reuptake of serotonin, making
more of it available at the synaptic gap and increasing serotonergic energy
Enzymatic deactivation - ANSWER✅✅destruction of a neurotransmitter by an
enzyme after its release
