So much of neuroscience is now based entirely on fMRI studies. But as Randall Munroe's latest webcomic points out, brain scans are not without their limitations.
The human brain has been described as a massively parallel computing machine. But just how powerful is it? A recent brain scan analysis is offering some unexpected results.
While watching Alfred Hitchcock, a man who has been in a vegetative state for 16 years exhibited similar brain patterns to healthy viewers, including parts of the brain involved in higher cognition and the processing of sensory information. The study "provides the best evidence to date that fMRI can be used to…
Behavioral psychologists have known for quite some time that people are more likely to harm others when they're part of a group. A new study suggests that "mob mentality'" happens when we stop reflecting on our own personal moral standards.
As any dedicated dog owner will tell you, canines often appear to grasp the emotional content of what's being said to them. An unprecedented brain scanning study now shows this is likely true — and that this capability pre-dates domestication.
See that walnut-like object in this brain scan? It's a tumor that needs to be removed. But to avoid damaging critical functions like speech and vision, surgeons have to see the brain's tangled web of connections. The solution? Just add water.
What you're looking at is a CT scan from an 8-year-old girl who was accidentally hit by a bullet fired into the air during a marriage celebration.
Yikes, this is all kinds of creepy. Stanford scientists recently took the EEG signals from a person experiencing a convulsive seizure and converted them to tones that fell within the acoustic spectrum of the human voice. The results will send chills up your spine.
When working with patients in a deep coma, doctors interpret a flat EEG reading as a sign that the person is brain-dead and with little chance of waking up. But a new Canadian study raises the possibility of ongoing brain activity beneath that flat line.
By using brain scan data and a set of computer algorithms, scientists from the Netherlands were able to determine which letters a person was looking at. The breakthrough suggests it'll soon be possible to reconstruct human thoughts at an unprecedented level of detail, including what we see, remember — and even dream.
An international research team has produced the first-ever ultra-high resolution 3D digital reconstruction of a complete human brain. At the astonishingly low resolution of 20-microns, the new scans are providing an unprecedented glimpse into the inner workings of the mind.
In a much needed breakthrough, neuroscientists have developed a technique to predict how much physical pain people are feeling by looking at images of their brain scans.
Temple Grandin, the world's most famous person with autism, is a "savant" who is known for her exceptional nonverbal intelligence, spatial reasoning, sharp visual acuity, and an uncanny gift for spelling and reading. Now, looking to understand how she is able to perform such amazing cognitive feats, a group of…
To date, geneticists have identified plenty of genetic markers that are correlated with intelligence. Taken individually, however, these account for a paltry 1% of the variation in IQ scores. But now, an international team of scientists has identified a set of genes that appear to amplify each other's effects —…
fMRI brain scans have been used in a few US court cases to determine whether people lied on the stand. But the technology remains controversial. Now a court case could decide whether fMRIs are the next lie detectors.
A new computer program lets your brain turn fMRI machines into musical instruments by assigning notes to active regions of your cortex. The results may cause people to drive themselves crazy just to stay on the cutting edge of electronica.
Neuroscientists think they've identified the part of the brain that causes Tourette's Syndrome, the condition that causes random tics including compulsive obscenity. How long before we can hack that part of the brain?
