But we largely know this already. What might surprise you are the details of this work. For instance, as neuroscientist David Eagleman writes in his book Incognito: The Secret Lives of the Brain: Your brain is built of cells called neurons and glia—hundreds of billions of them. Each one of these cells is as complicated as a city. And each one contains the entire human genome and traffics billions of molecules in intricate economies. Each cell sends electrical pulses to other cells, up to hundred of times per second. If you represented each of these trillions and trillions of pulses in your brain by a single photon of light, the combined output would be blinding. The cells are connected to one another in a netw...

During the month of August, many athletes train for the fall sports season, sometimes participating in two practices a day over the course of a few weeks.  While training is necessary and important for athletes to build up their stamina and to improve their performance, health consequences can be deadly if (more&#8...

The Phone Oximeter uses a traditional FDA approved pulse oximetry sensor, but researchers have modified it to interface with a phone, in this case, your iPhone. Currently the setup is being interfaced with an iPhone for trial studies, but is compatible with Android, and other mobile operating systems. What makes the Phone Oximeter special is its ability to capture SpO2 (blood oxygen saturation), heart rate, and respiratory rate — then dynamically comprehend the variables using the decision support software, giving...

The authors, who include some of the most prominent neuroscientists and ethicists in the world, warn that manufacturers are misusing the FDA’s humanitarian device exemption to promote deep brain stimulation as a “treatment” for obsessive compulsive disorder (OCD). In fact, they make clear that deep brain stimulation is very much an experimental procedure. Research is still at an early stage, and the risks to patients are not well defined. When suffering is severe and no other treatment has provided relief, there is value in making available an intervention like deep b...

Today I’ll describe what a participant goes through when they volunteer for a cognitive neuroscience experiment using a neuroimaging technique called electroencephalography (EEG). Unfortunately, it is exceedingly common for participants to not understand how these techniques benefit previous behavioral findings. Simply stated, if I were a participant, I’d like to know why I needed to wear a weird swim cap and how it benefits the research being done.

You don’t really want to know how long ago that was, but to give you a rough idea — I wrote it while wearing my bellbottoms. Back then I learned that infants initially smile as a type of reflex, almost as a way of getting them jump-started, but very soon afterward that grimace emerges into a social smile. They learn how to engage their caretakers, get some attention, be loved and, most importantly, survive. This means that a social smile has Darwinian value. But more than survival, a smile may be the doorway into understanding what brings us the good life. Resear...

The CervoCheck device is meant to be inserted into the vaginal canal/cervical opening where it then can measure electrical signals characteristic of contractions. Prototypes of the device are currently being tested in animals. We sympathize with those who have to insert them into pigs(?).

The lawsuit claimed Pharmacia, which Pfizer now owns, deliberately withheld results of a study showing Celebrex offered no safety advantages over less expensive meds, The Wall Street Journal writes. Pfizer argued that investors missed a two-year statute of limitations to bring the lawsuit. But the Alaska Electrical Pension Fund maintained there was no evidence of a possible fraud until The Washington Post published an article about missing Celebrex data in August 2001, which meant its April 2003 lawsuit was within two years of the statute.

The researchers claimed they had a new tool to help make a differential diagnosis of posttraumatic stress disorder (PTSD). The tool is a brain scanning technology that, like EEG, measures the brain’s electrical activity. But instead of directly measuring such activity, it measures magnetic fluctuations in the electrical activity. The technique is called MEG. There are certain technical benefits to this method as compared to a traditional EEG, so some researchers are exploring its greater use. Mind Hacks has a very good analysis of why the researchers’ claims were overreaching and a bit ridiculous: Crucially, the scan didn’t pick out cases of PTSD among people with ...

You may not be aware, but these devices — which deliver electrical impulses to your brain! — have never been tested by the FDA for either safety of efficacy. Let me repeat that – the FDA has never approved ECT devices for safety or efficacy. Doctors today can apply electrical impulses to your brain without having any government agency approve such treatment, despite the fact that ECT in most people results in sometimes-significant memory loss.

Yet that seems to be what’s happening in the profession of clinical psychology. A new journal article to be published next month by Timothy B. Baker, Richard M. McFall, and Varda Shoham (2009) suggests that psychology is falling apart. Specifically, the researchers argue that graduate training programs for psychologists studying to become psychotherapists has taken a wrong turn and needs to be turned around before it’s too late. So what steps could be taken to fix the apparent problem? Funny you should ask, because not only do the authors have a prescription, they actually started implementing their prescription more than a year ago. Is Psychology Like Medicine?

The first thing we need to do is ask the question “What is clinical interoperability?” The Institute of Electrical and Electronics Engineers or IEEE defines the term interoperability as follows: The ability of two or more systems or components to exchange information and to use the information that has been exchanged. I like this definition because it is short and sweet, but to truly understand interoperability, we need to go a little further. The first thing we need to do is add that clinical interoperability is about exchanging a specific type of information.  It is about exchanging clinical information about a patient that allows our ‘partner’ to leverage what we alread...

Skinner. The original behaviorist, Skinner was an American psychologist most famous for his work with operant conditioning — getting the desired behavior from a person or child through reinforcement, punishment and extinction. But like Freud, Skinner’s time was in the 1950s and the 1960s, a time when behaviorism was a fresh and new approach to tackling problems with human behavior and emotions — a direct reaction to the psychoanalytic school of thought that was prevalent throughout much of international psychology. Cognitive behaviorism, a reaction itself to Skinner’s strict behavioral paradigm, acknowledged the importance of other factors in human psychology — you can’t treat people like mice in a maze. Well, you can, but you get far mor...

This very sudden and deadly “electric explosion” that occurs inside the hearts of both old and young alike has long eluded scientists and researchers. The new research suggest that the tornado like activity of V-Fib and its electrical waves is organized into spiral vortices, no matter what species of mammal is experiencing the VF. These vortices or rotors as they are sometimes called, keep the heart’s pumping chambers from pumping in sync, thus disorganized impulses and ultimately death. The paper also shows that across animal species — from mice and guinea pigs to sheep and humans — the frequency of the VF activity can be scaled usin...

I wish. What would you say if I told you there existed a “school” in Massachusetts that caters to the most troubled youth the state has to offer. Using a set of behavioral modification techniques, they try their best to teach their students, while trying to maintain some sense of order. They have 250 adults and children at the school at any given time, and focus on serving people with autism, mental retardation, and emotional problems. Sounds okay, right?
