Module 7: Methods for Studying the Brain
When a person has a stroke, a blood clot prevents oxygen from getting to a part of the brain and causes neurons to die. Which is the best method for scientists to learn more about this kind of damage to the brain?
Lesion studies
This method used to study the human brain has not enabled psychologists to get a good picture of human brain functions
cadaver studies
Diamond's study of Albert Einstein's brain attempted to provide evidence that intelligence is determined by the number of glial cells in an individual's brain. What brain method did she use for her study?
cadavers
A difference between the fMRI and the TMS is that_________.
causal conclusions about the influence of brain structures on functioning can be drawn by the TMS but not by the fMRI
Dylan, 8-years old, has appeared to have had an epileptic seizure. He is rushed to the ER for treatment, and the admitting physician first orders some tests to be conducted on Dylan's brain to determine a diagnosis. Dylan will most likely receive an.....
electroencephalograph (EEG)
a noninvasive technique that uses magnetic fields to map brain activity by measuring changes in the brain's blood flow and oxygen levels is called
functionalMRI (fMRI)
Jack is injected with a small amount of radioactive glucose and then lies in a scanner. He is given a task-to think about his favorite song-as the scanner records the movement and location of the glucose his brain. A computer analyzes the data and produces a color-coded image of his brain activity. Jack is receiving the imaging technique called__________.
poistron emission tomography (PET)
An advantage of the PET scan is that it________, and a disadvantage is that it____________.
provides good images of brain activity; is an invasive imaging technique
An advantage of the EEG is that it___________, and a disadvantage of the EEG is that it___________.
provides good information on electrical brain activity, does not provide clear picture of brain structure
The electroencephalograph is a method of studying the brain that....
records electrical activity produced by the brain's neurons by using electrodes
Laboratory scientists want to study the effects of a specific neuron in the brains of mice. What brain technique are they most likely to use?
single-unit microelectrode
Brains of cadavers have provided helpful information about....
structures of the brains
Eisenberger and her colleagues conducted research to determine if a person's emotional pain originated in the same brain location as did physical pain. They tested their hypothesis by collecting brain activity data when participants played cyberball with others and then again when participants were excluded from playing cyberball with others. What brain technique did the researchers use to collect the participants brain activity?
Functional MRI (fMRI)
Melanie is suffering from severe depression, and medication has not seemed to help. Her physician suggests that she try a new, noninvasive brain technique to relieve her symptoms. This technique is called...
Transcranial Magnetic Stimulation (TMS)
Which neuroimaging technique can be used as a treatment for certain physical and psychological disorders?
Transcranial magnetic stimulation (TMS)
