Exam 3: The Biological Bases of Behavior

Hormones are like neurotransmitters; they are stored for subsequent release as chemical messengers and bind to special receptors on their target cells.

The nervous system that is made up of the somatic and autonomic nervous systems is the ____________________ nervous system.

The carriers of genetic information in the form of DNA are the

Imagine that you have stumbled across a secret laboratory where an evil scientist is conducting unauthorized brain research.By altering brain structures he has created superheroes that have specialized powers or abilities.One of these superheroes has a fantastic memory and is able to remember new information almost instantly.In this case,one of the brain structure that the scientist MOST likely altered would be

The "master gland" of the endocrine system is the

The seminal research on critical periods in neural development was conducted in the 1960s on which of the following subjects?

When this lobe of the brain is electrically stimulated,people report physical sensations as if they had been touched,for example,on the arm.

Imagine meeting four separate individuals who have each sustained injuries to different sections of their brain.Person A has irreversible damage to her frontal lobe.Person B has irreversible damage to his parietal lobe.Person C has irreversible damage to her temporal lobe and person D as irreversible damage to his occipital lobe.Briefly,what would be the effects of each of these injuries?

The amount of motor cortex devoted to each body area is determined by

Synaptic transmission takes place when the electrical neural impulse (action potential)jumps across the fluid-filled synaptic cleft between neurons much like the spark from a sparkplug does in an automobile.

With the exception of the sex cells,every cell in the human body contains

Which of the following research techniques is LEAST likely to be used to study the human brain?

Handyman Bob just hit his thumb with a hammer; the sensation will be transmitted to the central nervous system by ____ nerve fibers.

If the left hemisphere of the brain were damaged,which part of the body would be MOST directly affected?

____ nerves receive information,while ____ nerves carry out instructions.

The ____ fluid nourishes the brain and provides a protective cushion for it.

The difference in the flow rates of sodium and potassium ions across the cell membrane leads to

Ian has been in a coma since he was in a serious dive accident.He is still on medical life support because he is unable to breathe and his heart will not beat without assistance.It is likely that the accident caused damage to Ian's

Which research method allows researchers to MOST easily isolate the effect of both genetics and experience on specific traits?

Assume that developing a sixth toe is a recessive trait that is controlled by a single pair of genes.If a child has six toes,but both the child's biological parents have normal feet,you can conclude that
