Neuroscientists working on the Human Connectome Project have compiled the most accurate map yet of the human cerebral cortex. The researchers identified 180 distinct areas of the brain’s outer layer—effectively doubling the previous number of known regions.
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 —…
It's human nature (and human folly) to pretend like we know what our dogs are actually thinking about. Oh, he's happy! Oh, he's tired! Oh, he loves this! That's not exactly a scientific way to look at things. Brain scans, however, are super scientific. So scanning the brains of dogs means its possible to know what…
It was only matter of time after the invention of fMRI scanning machines — which track blood flow in the brain — that scientists would start having people pleasure themselves while strapped into one. And so it was that New Scientist writer Kayt Sukel ended up with this delightful scan of her brain at the moment of…
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.
This week, we're looking at the ever-increasing digitization of memory, and indeed, today's technologies can even access memories stored on the most closely-guarded of hard drives: our brains. In a recent study, MRIs accurately predicted what individuals were remembering.
I know it's science, which is ostensibly more objective than human intuition, but there's something unnerving about an MRI brain scan being admitted as evidence in a murder trial in Chicago, the first in the US.
