Those Kids and Their Crazy Hormones
Imagine you’re on your first date and you and your partner are hitting it off big time. It’s probably his/her witty comments or good sense of humor, his/her intelligence or impeccably beautiful smile that makes you feel extremely attracted to your date. As time goes on, you look deeply into each other’s eyes and giggle. […]
The Human Bias
Philosophers since the time of Plato have considered the extent to which we can truly perceive the physical world, or the so called ‘mind independent’ universe. Modern science has given us further insight into the question, through experiments designed to understand the way in which our brain receives and manipulates sensory information. While it has […]
New Blood Test Can Predict Alzheimer’s Disease
For years doctors have been able to detect the early symptoms of Alzheimer’s disease through scans, lumbar punctures, and genetic testing. While these methods can be painful or expensive, a new blood test has recently been discovered that can easily and accurately predict the onset of Alzheimer’s disease. Doctor Howard J. Federoff of Georgetown University […]
Temptation: The Effects of Immediate and Delayed Rewards
As we approach the loved holiday season, we also approach the dreaded weight gain that comes along with it. It probably won’t come as a surprise to you that our brain, specifically the hippocampus, plays a role in resisting immediate or delayed temptation. The hippocampus deals with memory, including recalling past events and imagining them […]
Which Way to the Brain Gym?
Intelligence is classically thought of as an immutable characteristic of each individual, pre-determined by genetics and permanent for a person’s entire life. But what if this is not true? It is an appealing idea to think that somehow, one can voluntarily, and naturally, boost his or her level of cognitive performance. Research has already shown […]
CLARITY Makes Brains “See-Through”
The science community received big news out of California last week as Karl Deisseroth and his team of researchers from the Department of Bioengineering at Stanford University had their paper concerning their newly developed CLARITY brain imaging technique published in Nature. The most astounding aspect of the newly released technique is that is creates a […]
Don’t Panic! – Mice Aren’t Actually the Smartest
“Man had always assumed that he was more intelligent than dolphins because he had achieved so much — the wheel, New York, wars and so on — whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were […]
Fire and the Evolution of the Brain
Behold – our recent ancestor, the gorilla, and ourselves, the human: There are many characteristics that separate us from our monkey fathers. Most notably, factors that mark the evolution are the use of fire, use of tools, and a bigger brain. A recent study suggests that it is actually the onset of the use of […]
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 […]
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 […]
