Which two methods of studying the brain reveal brain activity?

Electroencephalography (EEG) is used to show brain activity under certain psychological states, such as alertness or drowsiness. Positron emission tomography (PET) scans show brain processes by using the sugar glucose in the brain to illustrate where neurons are firing.

What shows changes in brain activity over time?

Functional magnetic resonance imaging (fMRI) operates on the same principles, but it shows changes in brain activity over time by tracking blood flow and oxygen levels. The fMRI provides more detailed images of the brain’s structure, as well as better accuracy in time, than is possible in PET scans (Figure 3).

Which of the techniques discussed would be viable options for you to determine how activity in the reticular formation is related to sleep and wakefulness Why?

Which of the techniques discussed would be viable options for you to determine how activity in the reticular formation is related to sleep and wakefulness? Why? The most viable techniques are fMRI and PET because of their ability to provide information about brain activity and structure simultaneously.

What methods are used by psychologists to study the brain and its role in behavior?

These technological methods include the encephalogram (EEG), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). These techniques ultimately have the same goal in that they aim to produce coherent representations of the brain.

Who performed the first experiment that proved increased brain activity will increase blood flow to the brain?

The development of FMRI in the 1990s, generally credited to Seiji Ogawa and Ken Kwong, is the latest in long line of innovations, including positron emission tomography (PET) and near infrared spectroscopy (NIRS), which use blood flow and oxygen metabolism to infer brain activity.

What refers to a person’s genetic makeup?

A person’s genetic makeup is called a genotype.

What refers to a person’s physical characteristics?

Physical characteristics are defining traits or features of a person’s body. These are aspects of appearance that are visually apparent to others, even with no other information about the person. They can include a variety of things. Hair and facial features play a big role but aren’t the whole picture.

What methods do scientists use to study the brain?

Some techniques that may be used for studying the human brain include:

• Electroencephalogram (EEG)
• Magnetoencephalography (MEG)
• Functional magnetic resonance imaging (fMRI)
• Photon migration tomography.
• Transcranial magnetic stimulation.
• Further Reading.
