The theory that states dreams represent wish fulfillment comes from which theory of dream interpretation?

Pons/Reticular Formation

Julissa Gomez, a young American gymnast, unsuccessfully attempted a difficult vaulting move, and struck her head. Damage resulted in paralysis and damage to a nearby region caused her to lapse into a coma. Where is the damage that caused her coma?

What will this individual be able to DRAW with his/her RIGHT hand? (Hint: Remember - each hemisphere controls the OPPOSITE side motor movements)

LEFT hemisphere controls the RIGHT hand (movement/touch). Therefore, the RIGHT hand can ONLY draw what the LEFT hemisphere processes. As a result, the answer is "ONLY CUP."

Parietal LOBE though yes - it was specifically Somatosensory cortex (of the right side) which is located within the parietal lobe

Margie suffered damage to part of the surface of her brain after being struck by a golf club let loose by an irate golfer that had just sliced a key drive. As a result Margie has loss some sensory awareness of her left leg. Which lobe did she injure?

Spinal Cord (via spinal reflex)

NBC reporter John Hockenberry took the Corningware pan of turkey stuffing out of the fridge and heated it on the stove. When the pan and contents were sizzling hot, the special handle was still cold. John set the pan on his lap for several minutes while he stirred and served the stuffing. He never noticed the burning hot bottom of the pan producing serious 3rd degree burns of his legs. John had suffered what type of injury which inhibited his ability to immediately pull back from the hot pan?

Treated through the use of stimulants (ex. amphetamines).

Narcolepsy

Uncontrollable urges to fall asleep.

Narcolepsy

More common in children and usually only appears during NREM - 3. Symptoms often involve heightened levels of freight and arousal.

Night Terrors

What will this individual be able to SAY? (Hint: Only ONE hemisphere contains to ability to speak - therefore it is EITHER cup OR pencil BUT not both)

ONLY CUP (Left Hemisphere = Language because of Broca/Wernicke's Area

Cerebellum

On Justin's 21st birthday he & his buddies celebrated a bit too much. When the police stopped his car Justin's speech was slurred, he couldn't walk a straight line or balance on one foot. He nearly missed his face altogether when asked to touch his nose while his eyes were closed. The impaired functioning of what part of Justin's brain is responsible for these difficulties with motor coordination and balance?

Constricted bladder

Parasympathetic Nervous System

Contracted pupils

Parasympathetic Nervous System

Decreased heart rate

Parasympathetic Nervous System

Hippocampus

Paul suffered from encephalitis (a brain infection) while in college. He received good medical attention but still the infection took its toll on certain parts of his brain, so that now Paul cannot store new long-term memories.

temporal lobe function

Processes auditory sensory information

Somatosensory cortex

Processes sense of touch

occipital lobe function

Processes sense of vision

Broca Area

Produces muscle movements necessary for speaking

Motor cortex

Producing motor movements (via motor neurons)

Reuptake

Prozac, a drug commonly prescribed to treat depression, prevents the sending neuron from reabsorbing excess serotonin from the synapse. Which process does this drug prevent from taking place?

facilitating or inhibiting neural transmission at the synapse

Psychoactive substances are drugs that alter consciousness by

What will this individual be able to DRAW with his/her left hand?

RIGHT hemisphere controls the LEFT hand (movement/touch). Therefore the LEFT hand can ONLY draw what the RIGHT hemisphere processes. As a result, the answer is "ONLY PENCIL."

Prefrontal cortex

Region of high level cognitive function (ex. planning)

Terminal Buttons

Region of the neuron that contains synaptic vesicles

Axon Terminal

Region of the neuron that contains the axon and myelin sheath

Dendrites

Region of the neuron that receives information from other neurons (at its receptor sites)

Pons/reticular formation

Regulates alertness and arousal

medulla function

Regulates automatic vital function (ex. breathing)

Cerebellum function

Regulates balance and smooth movement

Wernicke Area

Responsible for language comprehension and understanding

Loud snores that routinely wake the patient up at night.

Sleep Apnea

Treated through the use of a CPAP breathing mask or surgical procedure.

Sleep Apnea

More common in children and usually only appears during NREM - 3. Symptoms often involve carrying out behaviors that are usually seen while conscious (ex. walking).

Unaware of whether or not it is only a drill, Bobby is able to remain focused and alert after the fire alarm goes off.

It increases the speed of the action potential down the axon

What function is served by the myelin sheath that may cover an axon?

resting potential

When there is a negative charge inside an axon and a positive charge outside it, the neuron is

GABA

it has an all-or-none quality: it either happens, or it does not

Which of the following most accurately describes the firing of a neuron

Endorphins (Senerio)

While running a marathon, Miley experienced an increase in the body's natural painkiller.

The information-processing theory of dreaming states that dreams

occur during REM sleep as the brain deals with daily stress and events. (Thus helping consolidate memories from the day)
