Exam 3: Neuroscience and Behavior

Jenkins rapidly swivels his head to the sound of a car backfiring down the street,a behaviour made possible by his tectum.

When an infant suckles its mother's breast,the pituitary gland in the mother's brain secretes:

In a neuron,what happens when an action potential reaches the axon terminals of the neuron?

The actor Christopher Reeve died from complications related to:

Andy is walking down the street when suddenly a car honks its horn.Andy immediately swings his head in the direction of the sound,primarily a result of the functioning of the:

Which hindbrain structure is Latin for "little brain"?

The reticular formation is important for regulating sleep,wakefulness,and arousal.

During prenatal development,the tail end of the neural tube will develop into the _____,and the opposite end will develop into the _____.

PET scans and fMRI scans both measure brain function.

The hippocampus is critical for the formation of new memories.

There are more _____ than there are neurons in the brain.

Which lobe of the cerebral cortex is mainly involved in processing auditory information?

Use the following to answer questions : Scenario I The scenario is based on and presents fabricated data consistent with the following study: Caspi,A. ,Sugden,K. ,Moffitt,T.E. ,Taylor,A. ,Craig,I.W. ,Harrington,H. ,McClay,J. ,Mill,J. ,Martin,J. ,Braithwaite,A. ,& Poulton,R.(2003).Influence of life stress on depression: Moderation by a polymorphism in the 5-HTT gene.Science,301(5631),386-389. The serotonin transporter gene codes for the serotonin transporter,a protein that transports serotonin from the synapse to the presynaptic neuron.Several polymorphisms of the gene exist,including a "short" (s)and a "long" (l)variation.As humans receive one copy of the gene from each parent,people can be grouped into three groups based on this genetic variation: s/s (two copies of the short gene),s/l,and l/l.Caspi et al.(2003)interviewed participants in each of these groups and asked them a wide range of questions to determine both the degree of exposure to stress and the number of depressive episodes participants had experienced in their lives.Fabricated results consistent with their major findings are shown in Figure 3.1. Figure 3.1 -(Scenario I)A gene is a segment of _____ that codes for traits.

The two major subdivisions of the peripheral nervous system are sympathetic and parasympathetic.

GABA is the main excitatory neurotransmitter in the brain.

Figure 3.1 -(Scenario I)The serotonin transporter protein essentially _____ serotonin.

Each neuron has only one:

In an early experiment,severing connections in the reticular formation of a cat caused the cat to:

There are two special regions of the cortex dedicated to language,called Broca's and Wernicke's areas.Broca's area controls _____,and Wernicke's area controls _____.

Prozac acts as an antagonist for serotonin.
