"Stroking" Neurons
We have many different types of neurons within our peripheral somatosensory system. In addition to basic mechanoreceptors, we have neurons corresponding to pain sensations, and channels that are temperature sensitive. However, one phenomenon that was not explained at the neuronal level until recently, is the sensation of stroking. On the behavioral level, we know that […]
Turn That Frown Upside Down. Really, though. It’s Good for You.
It may be an age-old saying that makes most people groan whenever a friend or family member feels the need to say it, but there are actual psychological benefits that come from simply putting on a smile. Researchers have been examining this phenomenon for a few decades now and even though it is not a […]
Connectome Progress Report
The Human Connectome Project (HCP) has started trials on volunteers with a state-of-the-art scanner. Today’s technology allows neuroscientists to map the brain’s connections on an unprecedented level of detail. The ultimate goal of the HCP is to create a map, or connectome, of every neuron and synapse to better understand how the brain works. A […]
Mapping the Human Brain
By mapping the human brain, we will inevitably have a greater comprehensive understanding of how it functions. In this TED talk, Allan Jones explains how his team of researchers is mapping the brain by investigating which genes are turned on in each region and how these regions link up. According to Allan Jones: “Understanding how […]
Out of Madness Comes Life: Are The Arts Crazy?
Sometimes, writing is tough. The passion isn’t there, and every word is a struggle. We’ve all had those moments when forced to do something artistic or creative, whether it be writing or drawing or playing an instrument (or anything really). We’re just not into it, we don’t feel the pulse of the art pounding in […]
The Present State of Brain-Machine Interfaces
We live in an era where the rapid advances in technology are constantly changing how we perceive and interact with the world around us. The question on everyone’s mind is always “what’s next?” The answer: brain-machine interfaces. For the average consumer, brain-computer interfaces are becoming increasingly available on the mass market and their current uses offer […]
Maybe Being a Psychopath Isn’t Such a Bad Thing?
It’s Halloween, folks, and you know what that means: Jell-O molds of brains and punn-y costumes (Freudian Slip, anyone?), right? Amirite? Okay, maybe that’s just me, whatever, guys. But I can name at least one cherished Halloween pastime that tends to be pretty popular across the board, and that’s the horror movie marathon. As we […]
Tanning: A "Real" Addiction?
Tanning is just one of those things, like chain smoking or base-jumping, that I’ve never cared to try; I am nowhere near athletic enough to attempt jumping off of a mountain face. I am also too, well, white to bask in the natural sun without SPF 50 sunscreen; like most people with skin of Fitzpatrick […]
High Definition Fiber Tracking
There are numerous brain imaging techniques that allow us to gain insight into what damage the brain may have incurred after a patient has a traumatic injury. The ever popular fMRI measures blood flow to infer neural activity. Diffusion tensor imaging (DTI) uses the magnetic properties of water to look at white matter in the […]
Monitoring Brain Activity During Studying to Predict Test Performance
A research team led by Laura Matzen at Sandia National Laboratories in Albuqurque, NM has demonstrated that it is possible to predict how well people will remember information by monitoring their brain activity while studying. Matzen’s team monitored test volunteers with electroencephalography (EEG) sensors to make accurate predictions. Why bother making a prediction if the result will […]
