A. Convulsive Seizures

B. A Coma

C. Inability to Make New Memories

D. Modify in her Personality

Answer: The reticular germination, located in the old brain, plays an important office in arousal--our natural sleep-wake cycle.

A. His right temporal lobe

B. His hippocampus

C. Wernicke'due south Area

3.  The somatosensory cortex is to the ______ lobe as the motor cortex is to the _______lobe.

A. Parietal; frontal

B. Occipital; frontal

C. Frontal; temporal

D. Parietal; temporal

Reply: The somatosensory cortex is located in the parietal lobe; the motor cortex is located in the frontal lobe

4. Polarization is to __________ as depolarization is to _______.

A. Action potential; resting potential

B. Resting potential; refractory flow

C. Resting potential; action potential

D. Activity potential; refractory period

Answer: When a neuron is stimulated, gates are opened to allow for positively charged sodium ions to flood in, causing depolarization of the axon. This is called an action potential. As the activity potential moves downward the axon, sodium/potassium pumps restore the axon to its original land, that is is is polarized. This is called the resting potential.

Neural Firing

5. Juan was bit by a black widow spider. The venom is an agonist for ACh. What is Juan likely to be experiencing?

A. Paralysis

B. Migraine Headaches

C. Insomnia

D. Musculus spasms

Answer: ACh, or acetylcholine, is i of the best-understood neurotransmitters and can be found at every junction between motor neurons and skeletal muscles. Information technology enables muscle movement, and also plays a role in learning and memory. An antagonist is a molecule that enhances a neurotransmitter's action. The spider venom enhanced Jaun's musculus deportment, resulting in spasms

6. Night terrors are to ________ as hypnagogic sensation are to __________.

A. Stage 3; Stage ane

B. REM sleep; REM sleep

C. REM Slumber; NREM sleep

D. Phase 4; Stage 2

Respond: Night terrors, which are different than nightmares that occur during REM sleep, occur during Stage 3--about 2 or 3 hours after falling asleep. Hypnagogic sensations refer to the jerking or sudden feeling of falling that occur right when you are falling asleep ( Stage 1)

7. What is the role of the suprachiasmatic nucleus?

A. It increases the production of dopamine, causing us to experience pleasure

B. It blocks messages between our motor cortex and brainstem, causing paradoxical sleep

C. It suppresses the pineal gland'southward production of melatonin, causing us to awaken

D. Information technology interferes with our natural cyclic rhythms, causing insomnia

Reply: The suprachiasmatic nucleus (SCN) reacts to low-cal striking the retina. This sends a signal to the SCN to suppress the product of melatonin. At dark, the SCN quiets down, which allows for the release of melatonin and thus the feeling of sleepiness.

8. Aiko has been struggling with depression and finds it difficult to concentrate on her school work. It is virtually likely that Aiko has a shortage of which neurotransmitter?

A. GABA

B. Dopamine

C. ACh

D. Serotonin

Answer: Serotonin affects our mood, hunger, sleep and arousal and an undersupply has been linked to depression. Prozac and other antidepressant drugs enhance serotonin levels by blocking their re-uptake or chemic breakup

9. Neurotransmitters receptor sites are located on the

A. Soma

B. Dendrites

C. Axon

D. Terminal Branches

Respond: Dendrites are the neuron's branching extensions that receive the neurotransmitters and send the message (impulse) toward the prison cell body (soma). Neurotransmitters fit into the receptor cells much like a primal fits into a lock.

ten. Your ability to swat at a fly buzzing around your head is due to your

A. Somatic nervous organization

B. Autonomic nervous system

C. Parasympathetic nervous system

D. Endocrine organization

Answer: The somatic nervous system is part of the peripheral nervous system. It is responsible for gathering information and directing key nervous system decisions to your body parts.

11. The "uncommitted" areas of the cerebral cortex that are involved in higher-lodge cognitive functions and are more pervasive in more intelligent animals are called

A. Hemisphere lobes

B. Cortex interfaces

C. Association areas

D. Wernicke'south expanse

Answer: Association areas are involved in functions that make us human such equally learning, remembering, thinking and speaking. The fact that and so much of our brain is "uncommitted," has led to the myth that nosotros merely use x% of our brains.

The Brain

12. The role of the brain that links the nervous and endocrine systems is the

A. Pituitary Gland

B. Thalamus

C. Hypothalamus

D. Hormones

Answer: The hypothalamus, located in the limbic system just below (hypo) the thalamus, is responsible for maintaining homeostasis in our bodies. It secretes hormones that transport letters to the pituitary gland (the main gland) that in turn sends messages to all of the other glands in the endocrine organisation to release their hormones into the bloodstream.

13. What can be expected in someone who has been a long-term user of the drug Ecstasy?

A. An increased production of dopamine, resulting in hallucinations

B. Damaged serotonin-producing neurons, leading to depression

C. Reduced dopamine levels, resulting in depression

D. Decreased product of endorphins, leading to lower pain thresholds

Answer: Ecstasy, also known every bit MDMA or "Molly," is a stimulant and balmy hallucinogen. Information technology triggers dopamine release and blocks the reuptake of serotonin resulting in a experience-skilful rush of emotions and a feeling of connection with those effectually you. In addition to the damage to serotonin-producing neurons, Ecstasy also suppresses the nervous organization, impairs memory and can disturb the sleep bike.

14. Which of the following technologies would be most useful for determining what phase of slumber someone is in?

A. MRI

B. fMRI

C. PET Scan

D. EEG

Answer: An EEG, or electroencephalogram, amplifies the electrical activity of the brain'due south surface. Researchers are able to measure the waves by placing electrodes on the scalp. Each stage of slumber has a different type of wave associated with information technology (e.thousand. alpha, theta, delta).

xv. If a trait is found to be 85% heritable, what does that mean?

A. Information technology means that you are highly likely to inherit that trait if it is passed down to you past your parents

B. It ways that 85% of that trait comes from your genes and xv% from your experiences

C. It ways that 85% of the variation of that trait amongst individuals in a grouping tin can be attributed to genes

D. It ways that 85% of that trait can be attributed to your experiences and 15% to your genes

Answer: Heritability is often confused with the concept of inherited, but they are very different. Heritability is calculated by behavioral geneticists--oftentimes through their studies of identical twins. It is a statistical measure and refers to the proportion of variation among individuals in a group that can exist attributed to genetic makeup. If a trait is 85% heritable, it means that genetic influence explains about 85% of the variation amid people--not that 85% of that trait the trait is 85% genetic.
