Vitamin D deficiency and more and risk of ADHD

by Paul Whiteley in Questioning Answers

"Vitamin D – could it stop 'modern’ diseases?" was one of the headlines I read quite recently as more pressure is being applied on the sunshine vitamin to perform when it comes to our health and welbeing. Indeed, not so long ago I posted an entry updating where we're at when it comes to the 'sunshine' vitamin D and the autism spectrum conditions. The conclusion buried in that post was that whilst there is some interesting work potentially linking vitamin D and autism, there is still more to ........ Read more »

Can reducing ammonia production during exercise improve performance?

by AB Kirk in Stiff Competition

Ammonia may be a central player in fatigue and exhaustion.  Exercise releases of ammonia into the blood stream.  Once in the blood stream it travels to the brain where it can accumulate if the pace of entry is faster than the body’s ability to metabolize it.   Athletes in studies who had the hardest time completing […]

Curious publicity

by Janet Kwasniak in Neuro-patch

Our conscious image of what we are seeing usually appears complete; it is the whole visual field. This is an illusion. The image is built up from many narrower views of parts of the scene that we attend to in rapid succession. Our visual system also establishes a knowledge of the general balance of the […]...

Is your biological clock ticking? Maybe you should ignore it

by in Neuroscientifically Challenged

As I've transitioned into middle age, I've gotten used to seeing my Facebook feed filled with baby pictures, descriptions of charming family outings, and adorable quotations from the mouths of toddlers. If I knew nothing about what it were like to have a child (mine is just finishing up the terrible twos), I would assume from scrolling through these perfectly tailored social media portraits of others' lives that having kids is a non-stop fun-filled procession of treasured moments. Of course, thi........ Read more »

MERS-CoV orf4a -an antagonist of antiviral signaling

by thelonevirologist in Virology Tidbits

As mentioned in a previous entry MERS-CoV is capable to inhibit antiviral signaling by antagonizing interferon signaling pathways which are induced by the recognition of dsRNA by intracellular pathogen-associated molecular pattern (PAMP) receptors. Although having a ssRNA genome, dsRNA is produced during Coronavirus replication as an intermediate and thus can be recognized by Toll-like receptors -3 and -9 (TLR-3/TLR-9). ... Read more »

Why Do We Take Personality Tests?

by Psych Your Mind in Psych Your Mind

Personality tests are not new, but they have recently skyrocketed in popularity on the internet. This week, Buzzfeed published 15 such tests in one 24-hour period. It seems every day on my Facebook news feed, someone has posted new results from one of these quizzes. Online personality tests have expanded beyond the traditional format of telling us certain traits we possess, although those do still exist (try here and here). Now, there are also tests that give us information about ourselves by co........ Read more »

The better than average effect is even true in prison!

by Doug Keene in The Jury Room

You remember the better than average effect. It’s what makes us evaluate ourselves as better than others. I’m a better driver than the average driver. I’m a better swimmer than other non-competitive swimmers. Or even, I’m a better citizen than those who, unlike me, are not in prison. Yes. “I’m in jail. They are not. […]

An oral pheromone makes male wasps unattractive to females

by Brooke LaFlamme in Molecular Love (and other facts of life)

Communication is essential to any successful relationship, and insect relationships are no different. And, as in human relationships, much of this communication is non-verbal. Chemical cues in the form of pheromones help females of many insect species decide when to mate who to make with and, when the deed is done, other chemicals let them know it’s time to stop dating and get serious about making some babies.

Are The Mafia Psychopaths?

by Neuroskeptic in Neuroskeptic_Discover

The view that the Mafia is an organization of especially ruthless psychopaths is wrong – in fact, members of ‘Cosa Nostra’ have lower psychopathic traits than other criminals.
