It depends on the hallucinations. If visual - in the occipital lobe.

What method is most likely to be used when studying the patterns of electrical activity in the brain?

Electroencephalography (EEG) is the most common method used to study the patterns of electrical activity in the brain. EEG measures electrical signals produced by the brain's neurons through electrodes placed on the scalp, allowing researchers to analyze brain activity in different states and conditions.


Which two procedures allow researchers to visualize changes in brain activity over time?

the two procedures are the PET scan and the fMRI


The activation-synthesis theory says that: (Apex)?

C. Dreams are a by-product of brain activity during sleep.


Researchers today can use technology such as CAT scans and fMRI scans to measure brain activity. Some researchers ask their subjects to describe elements of their experiences (e.g. sensations images f?

Yes, researchers can combine neuroimaging techniques like CAT scans and fMRI scans with subjective reports from subjects to gain a more comprehensive understanding of brain activity. This approach can provide insights into how neural activity correlates with subjective experiences, helping to bridge the gap between objective measurements and personal perceptions. By integrating both objective and subjective data, researchers can potentially reveal deeper insights into the relationship between brain function and conscious experiences.

Which specific brain areas are most active while people recall familiar nursery rhymes researchers would be most likely to make use of a(n)?

Researchers would be most likely to make use of fMRI (functional magnetic resonance imaging) to study brain activity while people recall familiar nursery rhymes. Specific brain areas that might be most active during this task include the language processing centers in the left hemisphere of the brain, such as the Broca's area and Wernicke's area.


What is activation -synthesis theory?

dreams are a byproduct of brain activity during sleep


How do scientists study dreams?

Sleep researchers study the dreaming mind in sleep laboratories. Electrodes are connected to the heads of volunteers. These electrodes are linked to computers that sense the bioelectric activity inside the brain, indicating the different areas of the brain that are active during different stages of sleep. Researchers also track patterns of "Rapid Eye Movements" (REM) that indicate active dreaming. The volunteers are awakened during specific stages of sleep so they can report whether they are dreaming or not, and can describe their dreams. Researchers also use brain scanning equipment to observe the activity within the brain. Note: scientists cannot see the actual dream images the way the dreamer does, but scientists can observe, measure and track the activity of the brain as dreams occur. See attached links for more information.


What are the symptoms of Hallucinations?

Symptoms of hallucinations include seeing, smelling, or hearing things that are not present in the environment. Typical hallucinations involve seeing or hearing, but neither the eyes or ears have any physical problem. Instead, brain changes trigger hallucinations. Schizophrenics often experience hallucinations and many medications or street drugs can trigger hallucinations.


Can brain waves be measured?

Yes, brain waves can be measured using a device called an electroencephalogram (EEG). EEG measures the electrical activity in the brain by placing electrodes on the scalp, and it is used to diagnose various brain disorders and monitor brain activity during sleep or anesthesia.


What person is asleep the brain produces no electrical activity?

During deep sleep, the brain does exhibit reduced electrical activity compared to wakefulness, but it is not completely absent. The brain goes through different stages of sleep, with the deepest stage showing the least amount of electrical activity. This reduction in activity allows the brain to rest and recover, essential for overall health and functioning.
