This Squid Gives Better Side-Eye Than You

by Elizabeth Preston in Inkfish



Yes, this cephalopod is looking at you funny. It's a kind of cockeyed squid—an animal that looks like some jokester misassembled a Mr. Potato Head. One of the cockeyed squid's eyes is big, bulging and yellow. The other is flat and beady. After studying more than 25 years' worth of undersea video footage, scientists think they know why.

The Monterey Bay Aquarium Research Institute (MBARI) in California has been dropping robotic submarines into the ocean for decades. The footage from th........ Read more »

The Science of the Rorschach Blots

by Neuroskeptic in Neuroskeptic_Discover

When the psychiatrist Hermann Rorschach blotted ink onto paper to produce a series of abstract patterns, could he have known that nearly 100 years later, the Rorschach test would be a household name?



Although the use of the Rorschach to diagnose mental illness is mostly a thing of the past, research on the test continues. Last week, two new papers were published on the Rorschach blots, including a fractal analysis of the images themselves and a brain scanning study using fMRI.



The ... Read more »

Catatonic symptoms and autism

by Paul Whiteley in Questioning Answers

"Catatonic symptoms are more prevalent in young people with autism than previously thought" said the article recently published by Breen and Hare [1]. Continuing a research theme of at least one of the authors [2], the idea that catatonic symptoms - primarily manifesting as stupor, unresponsiveness to light, noise or touch, mutism, etc - might be over-represented when it comes to autism is not a new one by any means.Breen & Hare set about looking for "the presence and nature of such att........

This Is Why Squids End up with Mismatched Eyes

Deep sea creatures come with all kinds of strange features that help them to survive their cold, dark habitat.. Some have eyes the size of a basketball, others come with appendages that blink and glow, deep-sea dwellers have developed some strange features and the "cockeyed" squid Histioteuthis heteropsis has one normal eye and one giant, bulging, yellow eye.

Using Discourse Analysis to Assess Cognitive Decline

by The Neurocritic in The Neurocritic

Figure from Gauthier et al. (2005).

Alzheimer's Disease (AD) and other dementias are progressive neurodegenerative conditions that unfold over time. Subtle symptoms such as forgetfulness and word finding problems may progress to mild cognitive impairment (MCI), and then escalate to full-blown dementia. Recent efforts to classify prodromal states have included automated analysis of spontaneous... Read more »

Social interaction and autism: it takes two to tango

by Paul Whiteley in Questioning Answers

Psychology experiments are not generally fodder for this blog when it comes to autism. The main reason being that quite a few appearing in the peer-reviewed literature tend to look at quite abstract features perhaps somewhat removed from the daily lives of autistic people and their significant others. A few also seem to struggle with the idea that grand over-arching psychological theories (that seem to inevitably follow psychological findings in particular) are not required when it comes to auti........

The Fantasy of Connecting Two Spinal Cords

by Neuroskeptic in Neuroskeptic_Discover

A peculiar new paper proposes the idea of "connecting two spinal cords as a way of sharing information between two brains". The author is Portuguese psychiatrist Amílcar Silva-dos-Santos and the paper appears in Frontiers in Psychology.



Frontiers are a publisher with a troubled history of publishing dubious science. But this paper is unusual, even by Frontiers' standards, because it contains virtually no science at all.

In a nutshell, Silva-Dos-Santos suggests that it would be interest... Read more »

Why does music training increase intelligence?

We know that music training causes intelligence to increase, but why? In this post I 1) propose a new theory, and 2) falsify it immediately.

Vitamin D halting colds and flu?

by Paul Whiteley in Questioning Answers

"Overall, the study said one person would be spared infection for every 33 taking vitamin D supplements. That is more effective than flu vaccination, which needs to treat 40 to prevent one case, although flu is far more serious than the common cold."That was some of the media interpretation of the paper - "systematic review and meta-analysis of individual participant data" - published by Adrian Martineau and colleagues [1] looking at the collected data on vitamin D supplementation "on risk ........

"early medical events are associated with clinical ASD phenotypes"

by Paul Whiteley in Questioning Answers

The paper by Charlotte Willfors and colleagues [1] (open-access) provides some food for thought today and the observation that various individual and cumulative medical events - "early medical events likely to be caused by environmental factors" - may be important to at least some autism.Researchers "scrutinized the early medical histories of a rare and informative sample of 13 MZ [monozygotic] twin pairs discordant for clinical ASD [autism spectrum disorder]" also including "13 M........

"Dominance" Training Deprives Dogs of Positive Experiences

by CAPB in Companion Animal Psychology Blog

Dominance is an outdated approach to dog training – and it also means dogs miss out on fun.Approaches to dog training based on dominance rely on the idea that you have to be the ‘alpha’ or pack leader. Unfortunately, this type of dog training is not just out-of-date and potentially risky, but modern approaches to dog training are also a lot more fun – for you and the dog.What is dominance in dog training?We sometimes hear the phrase ‘my dog is being dominant.’ ‘Your dog is being do........

Tell it to the judge

The Complexities of “The Love Hormone”

by Miss Behavior in The Scorpion and the Frog

New York street art. Photo inWikimedia Commons posted by Pedroalmovar.Oxytocin, commonly known as “the love hormone”, is a small chemical that is produced in the brain of mammals, but can both act as a neurotransmitter and enter the blood stream and act as a hormone. It has long been heralded for its role in both maternal and romantic love, but more recent research is showing us just how complicated the physiology of love can be.Oxytocin is released in mammalian mothers after birth. It promo........ Read more »

Large-scale simulations of Langmuir Wave Distributions Induced by Electron Beams by H. Reid and E. Kontar

by CESRA in Solar Radio Science

Langmuir waves that generate type III radio bursts are excited by high-energy electron beams streaming out from the corona through interplanetary space. Despite a smooth temporal distribution of electrons, the Langmuir waves are measured to occur in discrete clumps, commonly attributed to the turbulent nature of the solar wind electron density (e.g. Smith and Sime 1979, Melrose et al 1986). But how do fluctuations in the background plasma shape the [...]... Read more »
