what lobe has sensory cortex
parietal lobe
If a body does not have enough potassium, how might that affect neuronal firing?
The neurons will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.
Which of the following describes what happens when a neuron sends a signal?
The neuron goes from being negatively charged to briefly being positively charged, and finally returns to being negatively charged again. The magnitude of the negative charge is fixed regardless of the strength of the input signal it receives.
A drug that is used to treat seizures functions by preventing inhibitory neurotransmitters from returning to the presynaptic neuron. This slows the rate of neurons firing by increasing the amount of the inhibitory neurotransmitter in the synapse. The drug is most likely to be classified as a
GABA reuptake inhibitor (GRI)
Which of the following best describes a major role of the thalamus?
It relays most sensory signals to the cortex.
Madeline has previously been diagnosed with major depressive disorder. She has an identical twin sister, Josephine, and a nonidentical sister, Abigail. Neither of Madeline's sisters have previously been diagnosed with major depressive disorder. Which of the following statements is true of Madeline's sisters?
Josephine is more likely to be diagnosed with major depressive disorder than Abigail in response to a stressful or traumatic event.
what happens at the synapse
One neuron sends a message to a target neuron--another cell
At a synapse, neurotransmitters released by the sending neuron do which of the following?
They bind to receptors at the receiving neuron, which opens ion channels.
What effect do agonists have?
They increase the likelihood that a postsynaptic neuron will fire.
An adult with a healthy sleep cycle is most likely to enter REM sleep
after cycling through the NREM sleep stages
Tyler and Hayden both often flew into a rage and started picking fights with each other.
amygdala (media temporal lobe) Processes fearful and threatening stimuli "fight or flight response"
A neuron sends a signal along its
axon
Antagonists function by
blocking receptors to prevent other neurotransmitters from binding to the neural receptors
The medulla oblongata is a part of the
brain stem
Sammy's speech was choppy, slow, and a grammatical mess.
brocas aphasia (broca's area, frontal lobe) responsible for speech production
Katie had problems coordinating her movement and keeping her balance.
cerebellum (back of brain) coordination
what do pons do
coordinate movements
Which hormone is released when a person is under stress?
cortisol
The psychodynamic theory of dreaming would postulate that
dreams fulfill unconscious wishes
The hormone most associated with the fight or flight response is
epinephrine
A person whose body is not producing enough testosterone is most likely to exhibit
fatigue
where is the frontal lobe
forehead
Lauren and Toni suffered from an impaired ability to plan, and make good judgments.
frontal lobe (directly behind the forehead) voluntary movement and expressive language
Danielle suffered from an inability to form new memories.
hippocampus (in the temporal lobe) learning and memory
Johnny often hits his brother even though his brother does not do anything to antagonize him. Johnny's aggression is most likely due to a combination of
his genetic makeup, the environment he grew up in, and the fact that aggression can be evolutionarily adaptive
Jeremy and Drew seemed to always be hungry and their temperatures ran high.
hypothalamus (undersurface of the brain) Keeps body's internal functions in balance . helps regulate appetite and body temperature
which hemisphere do deaf people use
left
which hemisphere is dominant
left
David lost the ability to move his right arm
left motor cortex (left side of the brain) Controls movement on right side of the body
Sara often kept falling asleep at odd times and in odd places.
pons (in the brain stem) respiratory rythym of breathing

where is the temporal lobe
side of head
Waking up frequently, loud snoring, silent pauses in breathing, and sleepiness during the day are symptoms of
sleep apnea
which lobe involves auditory learning
temporal
which lobe is easier to recognize faces
temporal
The phenomenon of declining physiological effects of taking a drug after sustained use is referred to as
tolerance
where is the parietal lobe
top to rear head
Wernicke's area function
understand speech
Natalie could no longer respond to her teacher because she didn't understand what she was asking.
wernickes aphasia (posterior third of the upper temporal convolution of the left hemisphere of the brain) comprehension of speech
where is the brocas area and what does it do
(frontal cortex) the motor speech area, speech production
Ruth and Debbie are identical twins who were raised by the same family. Vince and Frankie are identical twins who were separated at birth and raised by different families. According to research on the heritability of personality traits, Ruth's and Debbie's personalities are statistically
likely to be as similar and dissimilar to one another as are Vince's and Frankie's personalities
Amanda experienced irregularities in heartbeat and respiration rates.
medulla (base of the brain) breathing, blood flow, blood pressure, and heart rate
what does the hippocampus do
