is MRI can record dreams..?

not sure how accurate with this AI answer…

if someone know about this throw some light…

Yes, MRI can be used to record dreams. In 2012, a team of Japanese researchers used MRI scans to decode the visual content of dreams. They found that they could identify the images that people were seeing in their dreams with 60% accuracy.

The researchers used a technique called functional MRI (fMRI) to scan the brains of people as they slept. fMRI uses a magnetic field and radio waves to measure blood flow in the brain. When people dream, certain areas of the brain become more active, and this increased blood flow can be detected by fMRI.

The researchers then used a machine learning algorithm to analyze the fMRI data and identify the patterns of brain activity that were associated with specific images. They were able to create a database of these patterns, and then use this database to decode the visual content of dreams.

This study is just one example of how MRI can be used to study dreams. Other researchers have used MRI to study the emotional content of dreams, the cognitive processes involved in dreaming, and the neural mechanisms that underlie dreaming.

While MRI is a powerful tool for studying dreams, it is important to note that it cannot record dreams in the same way that a video camera can record a movie. MRI can only measure brain activity, and it cannot directly measure the images that people see in their dreams. However, the research that has been done using MRI has provided valuable insights into the nature of dreaming, and it has helped us to understand how dreams are generated in the brain.

fMRI cannot record dreams. What it records is neural activity (for reference this plot looks like waves). Neural activity cannot be overlayed to a visual cue, as in your neural activity can look the same but what you're thinking of can be different. In short, no. It cannot record dreams atleast the visuals you're thinking of, it can however get information about the neural activity.

seems there is some criticism also around this fMRI...

 

 

Criticism[edit]

Some scholars have criticized fMRI studies for problematic statistical analyses, often based on low-power, small-sample studies.^[113][114] Other fMRI researchers have defended their work as valid.^[115] In 2018, Turner and colleagues have suggested that the small sizes affect the replicability of task-based fMRI studies and claimed that even datasets with at least 100 participants the results may not be well replicated,^[116] although there are debates on it.^[117][118]

In one real but satirical fMRI study, a dead salmon was shown pictures of humans in different emotional states. The authors provided evidence, according to two different commonly used statistical tests, of areas in the salmon's brain suggesting meaningful activity. The study was used to highlight the need for more careful statistical analyses in fMRI research, given the large number of voxels in a typical fMRI scan and the multiple comparisons problem.^[119][120] Before the controversies were publicized in 2010, between 25 and 40% of studies on fMRI being published were not using the corrected comparisons. But by 2012, that number had dropped to 10%.^[121] Dr. Sally Satel, writing in Time, cautioned that while brain scans have scientific value, individual brain areas often serve multiple purposes and "reverse inferences" as commonly used in press reports carry a significant chance of drawing invalid conclusions.^[122] In 2015, it was discovered that a statistical bug was found in the fMRI computations which likely invalidated at least 40,000 fMRI studies preceding 2015, and researchers suggest that results prior to the bug fix cannot be relied upon.^[123][124] Furthermore, it was later shown that how one sets the parameters in the software determines the false positive rate. In other words, study outcome can be determined by changing software parameters.^[125]

In 2020 professor Ahmad Hariri, (Duke University) one of the first researchers to use fMRI, performed a largescale experiment that sought to test the reliability of fMRI on individual people. In the study, he copied protocols from 56 published papers in psychology that used fMRI. The results suggest that fMRI has poor reliability when it comes to individual cases, but good reliability when it comes to general human thought patterns^{[126][127][128}
