D) EEG
A) CT Scan
Series of X-ray photographs taken from different angles
Combined by computer into a composite representation
Bleedings, brain injury, skill fractures, blood clots, brain tumors
The parietal lobe is responsible for:
a) smell
b) decision making and judgment
c) vision
d) sensory and touch
d) sensory and touch
- Receives sensory input for touch, pressure, temperature, and body position
- On top of head, toward the rear
What sense skips the thalamus?
a) taste
b) touch
c) smell
d) hearing
c) smell
Smell goes straight the hippocampus
Thalamus is a the brain's sensory control center. All senses except smell pass through the thalamus.

a) sympathetic nervous system
b) central nervous system
c) somatic nervous system
d) peripheral nervous system
b and d) central nervous system and peripheral nervous system
Central- brain and spinal cord
Peripheral- sensory and motor neurons that connect the central nervous system to the rest of the body.
What do MRI's specialize in viewing?
a) soft tissue
b) electrical activity
c) blood flow
d) glucose activity
a) soft tissue
- An MRI is magnetic resonance imaging
-Uses magnetic fields and radio waves to formulate computer images of soft tissue to show brain anatomy.
Damage to the temporal lobe would most likely affect a person's ability to __________
a) hear
b) feel
c) see
d) smell
a) hear
The temporal lobe is responsible for hearing.
Receives information primarily from the opposite ear.
Above the ears.
As you guys are getting food, what part of the brain is being triggered?
a) hippocampus
b) cerebellum
c) thalamus
d) hypothalamus
d) hypothalamus
The hypothalamus is linked to emotion and reward. Part of the limbic system along with the hippocampus and amygdala.
What is the function of the parasympathetic nervous system?
Calms you down.
What scan records electrical activity of the brain?
an EEG
- Recording of the waves of electrical activity that sweep across the brain’s surface
- Machine looks like a shower cap
Someone slipped and fell on their back because of a banana peel and they are seeing spots. What lobe did they most likely hit?
a) occipital lobe
b) parietal lobe
c) temporal lobe
d) frontal lobe
a) occipital lobe
The occipital lobe receives information from visual fields (vision)
In the back of the head
What is the function of the reticular formation?
a) sensory control center
b) learning and memory
c) controls arousal and consciousness
d) reflexes
c) controls arousal and consciousness
The reticular formation is a nerve network that travels through the brainstem and thalamus.
What causes a "trip"?
Hallucinogens
- Causes changes in thoughts, emotions, and consciousness
- Change sensory perception
- DO NOT replicate a neurotransmitter
- LSD and acid
A PET Scan detects the presence of in the brain
Glucose
A PET scan is a visual display of brain activity and it detects where the radioactive form of glucose goes while the brain is performing a given task.
Which of the following is an incorrect connection between brain lobe and function?
a) Frontal Lobe - controls voluntary movements
b) Temporal Lobes - processes sound
c) Parietal Lobes - processes tactile sensations
d) Occipital Lobe - controls emotions
d) Occipital Lobe - controls emotions
Occipital Lobe controls vision
Which action would be most typically impaired when the cerebellum is depressed?
a) The ability to walk in a straight line
b) The ability to feel emotion
c) The ability to process visual information
d) The ability to incorporate new memories into a web of old knowledge
e) The ability to think abstractly
a) The ability to walk in a straight line
The cerebellum helps control balance, process sensory input, and coordinate involuntary muscles.
In rear part of the brainstem.
What drug simulates the release of endorphins?
a) cocaine
b) alcohol
c) heroin
d) ecstasy
c) heroin
Endorphins are linked to pain control and pleasure
cocaine --> dopamine
alcohol --> serotonin
ecstasy --> oxytocin

b) decline in creativity
c) speech impairment
d) loss in the ability to make inferences
c) speech impairment
Left side of the brain controls language.
What two parts of Phineas Gage's brain were severed? What was the result of this trauma?
The connection between his limbic system and frontal lobe were severed.
Limbic system- emotion and moral compass
Frontal lobe- judgment and decision making
He lost his moral compass and his personality was ruined.
What does the brainstem consist of (3 answers)?
Pons, medulla, and midbrain.
The brainstem is responsible for keeping you alive (breathing, heart rate, nervous system, sneezing, throwing up)
Medulla- controls heartbeat and breathing, reflexes, and involuntary functions (sneezing and vomiting)
Pons- unconscious processing, coordinates movements
Midbrain- vision and hearing, motor movement, eye movement, auditory and visual processing
What gland controls the other glands in the body?
The pituitary gland.
Under the influence of the hypothalamus and regulates growth and controls other endocrine glands.
