Parkinson's disease is a progressive loss of motor function due to the degeneration specific neurons. These neurons secrete an inhibitory neurotransmitter that prevents excessive activity in motor centers of the brain. What neurotransmitter is this?
dopamine
which of the following statements about metabotropic receptors is false?
1. all
2. their effects might be mediated by second messengers
3. they are responsible for fast neurotransmission
4. they are also called G protein coupled receptors

2
synaptic transmission can be terminated when the neurotransmitter is...
taken back into the presynaptic neuron, diffused away from the synaptic cleft and degraded by enzymes
Long term memory can be grounded in molecular changes called long term potentiation. this involves the binding of glutamate to NMDA receptors. Ca2+ is admitted into the dendrite and then the neuron does which of the following?
it produces even more NMDA receptors, making it more sensitive to glutamate in the future, it synthesizes proteins concerned with physically remodeling synapse, and it releases nitric oxide which diffuses back to the presynaptic neuron and triggers still more glutamate release
which of the following is not a dopamine pathway in the brain?
1. the reticulostrial pathway
2. the mesocortical pathway
3. the tuberoinfundibulnar pathway
4. the mesolimbic pathway

1
short term memory is associated with the - whereas long term memory is associated with the -
hippocampus ; cerebral cortex
which of the following occurs during rapid eye movement (REM) sleep?
the muscles are paralyzed, and body temperature, blood pressure, and heart rate and respiratory rate increase
confluent aphasia, due to a lesion in the - results in slow speech, difficulty in choosing words that only approximate the correct word
broca area
exhausted from studying all night, you briefly close your eyes and your mind starts wander. which brain waves would be most predominant in an EEG?
alpha
the puyramidal cells of the precentral gyrus are called - neurons
lower motor
after a stroke, a patient complains about lack of sensitivity in her right hand. The stroke most likely affected which part of the brain?
postcentral gyrus in the left parietal lobe
which of the following functions would most likely be controlled by the representational hemisphere of the cerebrum?
painting a picture
when people are asked to read aloud the name of each shape listed, they tend to take longer to read out the bottom line correctly, why do you think this is
intelligence quotient (IQ) level
in the EEG lab, electrodes were placed on areas of the head corresponding to the - lobe (s) of the cerebrum
frontal and occipital
EEG is one of the tools used in the diagnosis of...
epilepsy
- occurs when a subject opens their eyes and devotes their attention and the EEG rhythm changes to fast, irregular, shallow waves
alpha block
click and drag the terms on the left to accurately complete the sentences on the right
1. the person begins to feel drowsy and may experience a drifting sensation
2. high spikes in the EEG called sleep spindles occur. these are related to neuron interactions between the thalamus and cerebral cortex
3. theta and delta waves appear and they body vital signs begin to fall
4. entering slow wave sleep, the muscles are very relaxed, and the vital signs are at their lowest
5. REM occurs, which is when the eyes oscillate back and forth while the sleep is hard to awaken
