‘Cocktail Party Effect’ Deciphered

by United Academics in United Academics

When at a noisy party or simply in a crowded bar, it’s sometimes hard to focus on a single voice and pay attention to what the person is saying, but still we manage somehow to hear it among all the noise. This phenomenon is known as the “cocktail party effect”. Now two researchers at the University of California, San Francisco, have identified for the first time how it works in the brain....

Schizophrenia, for your entertainment

by Nerdy One in Try Nerdy

Just because something is “for your entertainment,” it doesn’t necessarily mean that this “something” is being ridiculed or mocked.

However, when the subject matter pertains to the devastating mental disorder schizophrenia, it’s important that the makers of the entertainment are conscientious about how the disease is portrayed. There’s already a lot of stigma about schizophrenia in society, including the misguided notion that schizophrenics are runnin........ Read more »

The Innate Irresistibility of Film

by Maria Konnikova in Literally Psyched

When I was seven years old, my mom took me to see Curly Sue. Though I don’t remember much of the movie, two scenes made quite the impression: the first, when James Belushi asks Alisan Porter to hit him on the head with a baseball bat, and the second, when Bill, Sue, and Grey sit [...]

How A Stroke Changed Katherine Sherwood's Art

by Neuroskeptic in Neuroskeptic

In 1997, American artist Katherine Sherwood was 44 when she suffered a major stroke. She writes about her experience and how it changed her work in a fascinating article just out, How a Cerebral Hemorrhage Altered My ArtAll of the images below are examples of her work, taken from the paper.Sherwood writes that she had long been interested in the brain. She incorporated neuroscience themes into her work even before the stroke. Here's a 1990 piece: Then, out of the blue, her life was changed:........ Read more »

Place cells: The importance of Patching

by TheCellularScale in The Cellular Scale

A place cell fires in one particular spot(source)Place cells are neurons in the hippocampus that fire when an animal is in a particular location. Like many other cases where a neuron activates in response to something specific, the question everyone wants to answer is 'why does the neuron fire at that particular spot?' A study published 1 year ago today used a quite difficult technique and a combination of patience and extreme persistence to look more deeply into the intracel........ Read more »

Patient DF uses haptics, not intact visual perception-for-action to reach for objects

by Andrew Wilson in Notes from Two Scientific Psychologists

Before functional neuroimaging techniques like PET and fMRI became common, what we knew about which parts of the brain did what came from neuropsychology. This is the study of patients with specific injuries to the brain, and the basic logic of the field is that if you have a patient with a lesion in area A who can't do task 1, then area A is involved in performing task 1. It gets a little more complicated than this, as you search for double dissociations, etc, but this is essentially it.A surpr........ Read more »

Stressful Life May Leads to Alzheimer's Diseases

by Vivek Misra in Uberbrain Research Frontier

Stress can be defined as any type of change that causes physical, emotional or psychological strain. However, not all types of stress are harmful or even negative. There are a few different types of stress that we encounter viz. Eu-stress, Acute Stress, Episodic Acute Stress, Chronic Stress. Stress manifests itself in the form of many psychological and physical problems like anxiety, hopelessness, anger, helplessness, egoism, expectation, tension, constipation, irritation, depression, apathy........

Big brains and Great Tits

by Nerdy One in Try Nerdy

For shame, dear reader — get your mind out of the gutter! Great Tits are adorable songbirds found commonly throughout Europe and Asia. And Christina Ricci (featured at left) is an actress whom I probably falsely assume has a relatively big brain behind her notoriously expansive forehead.

Rest assured, in this post I’ll be explaining how these concepts are related, and what the latest research has to say about why our brains are so much bigger than they need to be.... Read more »

There is a recent study by Scheinin of Turku Finland, his team, and collaborators from U of California. (see citation below). They looked for the neural correlates of consciousness. This is a very interesting study.

A Case Against Eating Disorder Not Otherwise Specified (EDNOS)

by Tetyana in Science of Eating Disorders

This study is a follow up on the previous study (last entry) which examined the problems with the EDNOS classification, the frequency of transitions between eating disorders and how the DSM should be changed to reflect the clinical reality of eating disorders (and what is the clinical reality?.

In this 2010 Eddy et al paper, the authors followed 246 women who were initially diagnosed with either AN or BN, for an average of 9 years. The main goal was to study the growing disparity between (1)........ Read more »

Competitive versus cooperative #exergame play on Cognitive Function

by Stephen P. Yang, Ph.D. in ExerGame Lab

For at-risk ethnic minority adolescents, exergaming helped them lose weight (over 10 weeks) and improved executive function skills when compared to a control group. Although there have been many studies in exergaming, most of it has centered around physiological outcomes, but this is one of only a handful of studies that measured cognitive function over a period of time. This study is from Amanda's 2010 dissertation from Georgetown.

Real or Not Real: NeuroTorture

by TheCellularScale in The Cellular Scale

I am not going to lie, I recently got caught up in Hunger Games fever, tearing through all three books at a breakneck pace and staying up way too late doing so. While these books raise interesting questions on some of my favorite topics (like 'how much is too much to sacrifice for victory?'), one particular neuroethics issue jumped out and stung me.Without divulging any plot points or spoilers, I will explain:In the last book, Mockingjay, a good guy is taken hostage by the bad guys.&nb........

Clothes make the man—literally

by Jordan Gaines in Gaines, on Brains

A study by Hajo Adam and Adam Galinsky of Norwestern University observed an interesting phenomenon: wear a white coat you believe belongs to a doctor, and you'll be more focused. Wear a white coat you believe belongs to a painter, and you won't see that improvement. In other words, clothes may literally make the man (or woman).... Read more »

The Instability of Eating Disorder Diagnoses

by Tetyana in Science of Eating Disorders

Eating disorders are rarely static. Symptoms fluctuate, waxing and waning as circumstances change. Often, these fluctuations lead to diagnostic crossover – between subtypes of one disorder or to a different eating disorder altogether. The heterogeneity of symptom severity and frequency led to the establishment of the “eating disorder not otherwise specified” diagnosis in the Diagnostic and Statistical Manual. Essentially, it is everything that doesn’t quite fit into the “anorexia nervo........ Read more »

Brainbrawl round-up

by Zen Faulkes in NeuroDojo

Columbia University hosted a debate between Tony Movshon and Sebastian Seung last Monday, “Does the brain’s wiring make us who we are?” This became known informally as “brainbrawl.” I watched it livestreamed through the Radiolab site, and someone had the wherewithal to grab the video below (which Radiolab said they weren’t planning on archiving). Radiolab did archive the live chat here.



Where’s the fight?

As I predicted, it was a much more sedate affair than the “brainbrawl........ Read more »
