Inflammation of the Brain and Memory Problems

by Gabriel in Lunatic Laboratories

Neurological disorders typically involve memory issues. Most of the problems are attributed to plaques that build up in the brain (which are typically prions), yet some causes are unknown. New research however sheds some light on at least one cause of memory problems. As it turns out brain inflammation can rapidly disrupt our ability to retrieve complex memories of similar but distinct experiences.... Read more »

Insulin, growth hormone and risk of schizophrenia?

by Paul Whiteley in Questioning Answers

"Overall, the present findings suggest that metabolic and hormonal disturbances such as effects on insulin and growth hormone may represent a vulnerability factor to develop mental disorders". That was the conclusion reported by van Beveren and colleagues [1] (open-access) looking at "disruption of insulin and growth factor signaling pathways as an increased risk factor for schizophrenia"."Years ago you served my father in the Clone Wars"Drawing on data derived from participants taking part in&n........

Psychologists have compared the mental abilities of Scrabble and crossword champions

by BPS Research Digest in BPS Research Digest

Completed Scrabble (left) and crossword grids (image from Toma et al 2014).Every year, hundreds of word lovers arrive from across the US to compete in the American Crossword Puzzle tournament. They solve clues (e.g. "caught some Z's") and place the answers (e.g. "sleep") in a grid. Meanwhile, a separate group of wordsmiths gather regularly to compete at Scrabble, the game that involves forming words out of letter tiles and finding a suitable place for them on the board.Both sets of players have ........

An efficient magnetic field can exist for light particles

by Usman Paracha in SayPeople

Main Points:

Scientists have opened a new window in science by finding that an effective magnetic field can exist for light.
Published in:

Nature Photonics
Study Further:

Magnetic field refers to the line of forces that are present around the permanent magnet or a moving charged particle. This field can change the path of charged particles such as electrons. Usually, magnetic field has no effect on neutral particles such as photons, which are present in light. However, the present stu........ Read more »

Astrocyte role in gamma waves

by Janet Kwasniak in Neuro-patch

The study of the brain has been very neuron centered. Glial cells outnumber neuron by about 10 to 1 in the cortex and are known to be important to brain function but it is not clear just what they do other than some housekeeping tasks and shepherding neurons to their final locations during development. Astrocyte […]... Read more »

Transcendental idealism and Post’s variant of the Church-Turing thesis

by Artem Kaznatcheev in Evolutionary Games Group

One of the exciting things in reading philosophy, its history in particular, is experiencing the tension between different schools of thought. This excitement turns to beauty if a clear synthesis emerges to reconcile the conflicting ideas. In the middle to late 18th century, as the Age of Enlightenment was giving way to the Romantic era, […]... Read more »

As your therapist likely tells you, understanding where you came from is key to accepting where you are now. Take that therapist’s task and multiply it by several million—you now understand the tough job ahead of developmental biologists trying to track cell lineages in complex organisms. Today’s colorful image is from a paper describing a new computational framework for reconstructing cell lineages. The successful tracking of cell position, division, and movement in a developing or........

SARS-CoV: formation of the RTC and mitophagy; role of p6 and orf9b

by thelonevirologist in Virology Tidbits

Whilst the nature of the RTC and the role of the CoV non-structural proteins as well the potential role of these proteins in the ER stress response have been discussed in detail before, the role of p6 has been not been discussed. p6 not only induces the formation of membranous vesicles but also recruits nsp-8 to nsp-5, the main viral RNA Polymerase, and induces a ER stress response.
Also the role of SARS-orf9b in the induction of mitophagy is discussed.... Read more »

The Origami Brain and a new marker for Schizophrenia

by Gabriel in Lunatic Laboratories

Anyone who has seen pictures or models of the human brain (like the one above) is aware that the outside layer, or cortex, of the brain is folded in an intricate pattern of “hills”, called gyri, and “valleys”, called sulci which give the brain it’s distinctive look. It turns out that the patterns of cortical folding are largely consistent across healthy humans, broadly speaking. However, disturbances in cortical folding patterns suggest deeper disturbances in brain structure and functi........ Read more »

The illusion that gives you sensations in a rubber tongue

by BPS Research Digest in BPS Research Digest

Our sense of where our bodies begin and end usually feels consistent and reliable. However psychologists have been having fun for decades, exposing just how malleable the body concept can be.You may have heard of the "rubber hand illusion" (video). By visibly stroking a rubber hand in time with stroking a participant's hidden real hand, you can induce for them the feeling of sensation in the rubber hand.The rubber hand illusion is thought to occur because the brain tends to bind together informa........

Treating autism in the first year of life

by Paul Whiteley in Questioning Answers

I had been waiting y'know. Waiting a while for the paper by Sally Rogers and colleagues [1] to finally appear quite a few days after the media headlines about 'reducing', 'reversing' and even 'eliminating' the signs and symptoms of autism in early infancy had appeared. Personally, I prefer the New Scientist headline: 'Early autism intervention speeds infant development' given the text of the paper. I should perhaps also add the words 'for some' to that sentence as you will hopefully see...I........ Read more »

Stop Worrying, Good-Looking Dudes: Your Sperm Is Fine

Omega-3 fatty acids rescues Fragile X phenotypes in Fmr1-Ko mice
