A supposedly memory-enhancing commercial brain-stimulation device actually impairs memory

by BPS Research Digest in BPS Research Digest

It's easy to understand why so many people have been tempted by the futuristic-looking foc.us brain stimulation headset. The manufacturers promise their product will increase brain speed and plasticity and improve mental abilities such as working memory. What's more, the device uses a technology that's usually described as "non-invasive" – transcranial direct current stimulation, or tDCS for short – to send currents apparently safely into your prefrontal cortex.There is ample lab r........

Feeling blue and seeing blue: Sadness may impair color perception

by Dr. Jekyll in Lunatic Laboratories

The world might seem a little grayer than usual when we’re down in the dumps and we often talk about “feeling blue” — new research suggests that the associations we make between emotion and color go beyond mere metaphor. The results of two studies indicate that feeling sadness may actually change how we perceive color. Specifically, researchers found that participants who were induced to feel sad were less accurate in identifying colors on the blue-yellow axis than those who were led to ........ Read more »

Managing Fatigue in Match-Play Tennis

by William Yates, M.D. in Brain Posts

The 2015 U.S. Tennis Open is in full swing and I ran into an interesting recent manuscript summarizing fatigue in tennis.Fatigue has multiple elements including changes in muscle performance, blood markers of lactic acid and other compounds as well as brain central perception factors.Long multi-set matches can last four or five hours. Obviously, at the end of this type of exertion, players have had to adjust to effects of significant fatigue.Reid and Duffield review the key elements of fatigue i........ Read more »

Video Tip of the Week: ENCODE Data Coordination Center, phase 3

by Mary in OpenHelix

The ENCODE project began many years ago, with a pilot phase, that examined just 1% of the human genome. But this initial exploration helped the consortium participants to iron out some of the directions for later stages–including focusing on specific cell lines, techniques, and technologies in Phase 2. There have been a number of publications […]... Read more »

Preparation Makes a Difference to Pets in an Emergency

by CAPB in Companion Animal Psychology Blog

After the Great Earthquake in Japan, preparation was key to evacuating with pets - including training and socialization.When the magnitude 9 earthquake struck Japan in 2011, causing a tsunami and subsequent accident at the Fukushima nuclear plant, over 15,000 people were killed. Many people had to evacuate at short notice. In 2012, pet owners from two of the most badly affected areas, Iwate and Fukushima Prefectures, were asked about whether or not they took their pet and the types of planning t........ Read more »

Don’t Disrespect The Dizygotic

by Mark Lasbury in As Many Exceptions As Rules

Spies try to look boring, but in reality they are much more interesting than the average Joe. So it is with dizygotic twins; monozygotic twins (“identical”) get all the glory, but they’re just a split egg, any female can do it. But dizygotic twins – certain families have more, Nigerian women have more, older women have more, taller women and overweight women have more. Now there’s something that looks boring but must be interesting.... Read more »

Sub-threshold autistic traits and creativity

by Paul Whiteley in Questioning Answers

I was intrigued by the results reported by Catherine Best and colleagues [1] recently and the suggestion that yet another sweeping generalisation attributed to autism (or at least autistic traits) might turn out to be not as accurate or universal as we might have all been led to believe.Based on the analysis of data from over 300 people who completed an on-line questionnaire (anonymously) measuring autistic traits, researchers reported that creative ideas as measured by a divergent thinking task........

Does Everyone Dream?

by Neuroskeptic in Neuroskeptic_Discover

Everyone dreams - even people who believe that they "never dream" and can't remember any of their dreams. That's according to a group of French researchers writing in the Journal of Sleep Research: Evidence that non-dreamers do dream.





In questionnaire surveys, up to 6.5% of people report that they 'never dream'. Although most of these people report having dreamed at some point in the past, roughly 1 in every 250 people say that they can't remember ever dreaming - not even once.

But... Read more »

Researchers help identify neural basis of multitasking

by Dr. Jekyll in Lunatic Laboratories

What makes someone better at switching between different tasks? Looking for the mechanisms behind cognitive flexibility, researchers have used brain scans to shed new light on this question. By studying networks of activity in the brain’s frontal cortex, a region associated with control over thoughts and actions, the researchers have shown that the degree to which these networks reconfigure themselves while switching from task to task predicts people’s cognitive flexibility....

Parasitized Bees May Self-Medicate with Nectar

by Elizabeth Preston in Inkfish



Mary Poppins taught us that a spoonful of sugar makes the medicine go down. A bumblebee's favorite sugary drink may already be laced with medicine. And bees seem to dose themselves with medicinal nectar when they're suffering from a gut full of parasites.

Plants manufacture many chemical compounds to defend against attackers. Some of these are familiar to humans—like capsaicin, the potent weapon made by chili pepper plants. But not every animal enjoys painful food experiences like we do........ Read more »

The blastocyst achieves on-time implantation by entosis

by Xiaofei Sun in the Node

The process of embryo implantation consists of multiple steps: blastocyst apposition, adhesion to uterine luminal epithelial (LE) cells, and removal of the epithelial cells encasing the blastocysts. How the blastocyst trophectoderm breaches the luminal epithelial barrier has been studied for decades, the mechanism of the abstraction of LE cells was not clearly understood. Since the[...]

Let's talk about sex and autism (reviewed)

by Paul Whiteley in Questioning Answers

The review from Nicola Beddows and Rachel Brooks [1] highlighting the important issue of sexual behaviour with autism in mind is brought to your attention today.Trawling through the peer-reviewed literature looking at reports of inappropriate sexual behaviour present in adolescents diagnosed with an autism spectrum disorder (ASD), the authors concluded that various behaviours were included and that there were a variety of possible reasons for said behaviours. Indeed they report that: "Despi........ Read more »
