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
