Exam 3: Neuroscience and Behavior

The heritability index for major depressive disorder is approximately .37,meaning that:

The thalamus does NOT receive information from:

Low levels of which neurotransmitter have been implicated in Parkinson's disease?

Which gland(s)is/are the sexually reproductive gland(s)in men?

A medical artist is drawing a homunculus with body-part size in relation to the size devoted to it in the somatosensory cortex.Which body part should be drawn LARGEST?

Which function is NOT one that pertains to the cell body?

The electrical charge of a neuron at rest is largely the result of a chemical "pump" that pulls _____ from outside to inside the neuron.

_____ is found in the junctions connecting axons to skeletal muscles and organs such as the heart.

Researchers studying opiates such as morphine were surprised that they fit exactly into neural receptors.The reason is that the brain produces its own version of an opiate for pain relief,called:

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)Variation in the serotonin transporter gene was not predictive of depression:

Functional magnetic resonance imaging (fMRI):

Presynaptic is to postsynaptic as:

Corey was struck in the back of the head with a baseball bat.After the blow,she had difficulty with balance and coordinated movements and experienced problems with walking and riding a bike.Which brain structure was probably damaged?

The probability of sharing genes is termed:

The _____ is involved in regulating posture.

The striatum is a part of the basal ganglia involved in movement.

Prozac works by:

The electroencephalograph (EEG)is used to measure brain structure.

The drugs used to treat depression often enhance the processing of neurotransmitters such as serotonin by:

Use the following to answer questions : Scenario II In pioneering research by Sperry and colleagues,split-brain patients were asked to stare at a dot on a screen centered between their eyes,while words of common objects were projected onto the screen either in their left or right visual fields.Subsequently,patients were asked to reach behind a screen with either their left or right hands and identify the object among other common objects by touch alone. -(Scenario II)The split-brain surgical procedure is almost always performed to reduce:
