Exam 2: Cognitive Neuroscience

You are a biological psychologist and you must figure out what symptoms or effects certain diseases have on each of your participants.One participant has Korsakoff's syndrome,one is a split-brain patient,and the third has had an ischemic stroke.Briefly explain the effects or accompanying symptoms of each of these people.

Although the brain makes up only one fortieth of the total weight of the adult human body,it uses __________ of the circulating blood,available oxygen,and available glucose.

These cells in the brain transmit electrical signals from one location to another in the nervous system.

Imagine that the brain had no hemispheric specialization and no modularity.What would be the implications for such a brain (include issues such as learning,brain damage,brain development,etc. )?

You have just stepped on a nail protruding from the floor.Describe the various processes involved in relaying information from the time you step on the nail to the time you pull your foot away.Be sure to include effecters and receptors in your discussion.

The approach to studying the brain in order to understand what specific part of the brain controls what specific skills or behaviors is called _____.

At the end of the branches of an axon are the ____,which look like small knobs.

This particular way of looking at the brain divides up the cerebral hemisphere into four parts called

When viewing a picture that is half one person's face and half another person's face,a split brain patient would

Explain the similarities and differences between the various types of metabolic imaging techniques.Include in your explanation when you might use one over another.

This particular part of the hindbrain "contains neural fibers that pass signals from one part of the brain to another" and thus serves as a relay station.

This static imaging technique uses a strong magnetic field to analyze "magnetic changes in the energy of the orbits of nuclear particles in the molecules of the body."

Marc Dax noticed a relationship between the loss of speech and the side of the brain in which damage had occurred in patients suffering from

Split-brain patients sometimes have difficulty reconciling information that is __________ (largely localized in the left hemisphere)with information that is __________ (generally localized in the right hemisphere).

This particular neuroimaging technique is able to look at changes in the brain over time by looking at increases in oxygen consumption to produce an image of the brain.

Many soldiers are returning from the war with closed-head injuries.What has occurred?

How can researchers trace observed behavior resulting from brain damage to a certain location in the brain once a patient has died? Contrast this method with other methods used while the patient is alive.

All of the following are central interconnected cerebral structures of the limbic system except the

This particular type of metabolic imaging technique uses a radioactive form of glucose "that emits positrons as it is metabolized" to look at the physiological functioning of the brain "in action." It monitors increase in blood flow to particular parts of the brain.

Generate various scenarios in which an individual has a head injury from say a car accident (include injuries from front,back,top,and the sides).Include both closed and open-head injuries and describe how the injuries would alter function.
