Study of the function of the living human brain is difficult because
All of the Above
_________ measures the electrical currents generated by the brain.
Electroencephalography
The spatial resolution of EEG is limited by
Conductivity issues and the inverse problem
Which technique uses a radiofrequency wave to excite hydrogen atoms in the brain to generate an image of the living human brain?
Magnetic resonance imaging
Which of the following is a histological method?
All of the above are correct.
Which of the following is true of the interaction of magnetic fields and brain function?
All of the above are correct.
Which of the following techniques would be used to trace efferent axons from a brain region to other brain regions?
An anterograde labeling method.
A key advantage of the fMRI technique is that the method can
record the neural activity of particular brain regions
Which device below might be used to record the electrical activity of a single nerve cell in an animal brain?
Microelectrode
An experimenter wishes to determine the effect of a radiofrequency lesion placed in the lateral hypothalamus on emotional behavior in the rat. In order to be able to attribute any changes in emotional behavior to the lesion, this experiment will require a
sham-lesion control group
The key rationale for lesion studies is that
the change in behavior that follows a brain lesion can give important clues about a function of an ablated brain area.
A key advantage of ________ lesions is that they affect only neural cell bodies and do not damage axons passing through the region
excitotoxic
Which of the following is true of the experimental ablation technique?
All of the above are correct.
The temporal resolution of fMRI is limited by
Sluggish nature of blood flow
_________ measures changes in blood oxygenation in the brain
functional Magnetic Resonance Imaging
