This part of the brain, known as the “sensory switchboard,” sits atop the
brainstem and relays messages between lower brain centers and the cerebral cortex
Thalamus
This part of the cerebral cortex controls sensation
and helps with the processing of
mathematical, spatial associations
Parietal lobe
What type of input must be received for a neuron to
generate an action potential?
More excitatory input than inhibitory input to surpass the “threshold” and cause neuron
to “fire”
Chemical substances that mimic or enhance the
effects of neurotransmitters are known as __Agonist____.
The most common excitatory neurotransmitter, it is released by over half of
the neural synapses and plays a role in learning and
memory formation
Glutamate
This part of the nervous system becomes
engaged when we are aroused and expend
energy
Sympathetic nervous system
Heartbeat, digestion and other involuntary
processes are controlled by this part of the nervous system
Autonomic nervous system
This is the part of the nervous system that controls voluntary
muscles
Somatic nervous system
Which part of the nervous system is active when our appetite returns and our heartbeat slows following
exercise?
Parasympathetic nervous system
If John burns his hand on a candle, the pain message
would be carried to his spinal cord by the
_____________ nervous system
Somatic nervous system(Sensory neurons)
Considered to be the “master gland,” it is
located in the brain and releases hormones that
influence growth
Pituitary gland
Which hormone, released by the endocrine
system’s sex glands, stimulates growth of the
male sex organs?
Testosterone
Final Question
This naturally produced chemical in the body modifies the action of neurotransmitters as it binds
to neurons and impacts our perception of pain
Endorphins
This gland is located in the neck and regulates
metabolism
Thyroid
Epinephrine and norepinephrine are
_________ that are released by the _______ gland
Hormones; adrenal
This tool allows us to study the electrical
activity in the brain by providing an amplified
read-out of the waves of electrical activity
EEG
The brain research technique involves the
monitoring of the brain’s usage of glucose and
generates images similar to that below
PET Scan
The image below depicts brain activity shown through which brain
researching technique?EEG
Early forms of brain research that involved
the natural or experimental destruction
of brain tissue were known as
____Lesioning____
How is the fMRI different from the MRI scan?
Multiple images
What does it allow researchers to see?
Brain activity – oxygen consumption shows blood
flow
Which group is more likely to develop the same mental illness?
Fraternal twinsor
Identical twins
Gender refers to…
Biological and social definition of male and
female
A pair of adopted children raised in the same home are most likely to have similar
_________________
Manners, values, beliefs
What have adoption studies revealed about the
personalities of adopted children?
Temperament and personality are more closely aligned to biological parents
To say that the heritability of a trait is
approximately 50 percent means…
When considering variation of a trait within a group of people, 50%
can be attributed to genes
