Babies chew on subtle social, cultural cues at mealtime

by Dr. Jekyll in Lunatic Laboratories

At the dinner table, babies do a lot more than play with their sippy cups, new research suggests. Babies pay close attention to what food is being eaten around them - and especially who is eating it. The study adds evidence to a growing body of research suggesting even very young children think in sophisticated ways about subtle social cues.

Obesity Surgery: VA Outcome Study

by William Yates, M.D. in Brain Posts

Weight loss (bariatric) surgery is likely to become increasingly important to address the obesity epidemic in the U.S. and other nations.There are several types of surgical techniques used for bariatric surgery.One of the most invasive is the Rous-en-Y gastric bypass (RYG) operation. This operation involves bisection of the small intestine and reattachment of the upper section to a position lower down the small intestine. This provides for a shorter distance for food to be absorbed.Less invasive........ Read more »

Mitochondrial function during muscle fiber type transition by a miR‐499/Fnip1/AMPK circuit

by Joana Guedes in BHD Research Blog

Contractile fiber type and mitochondrial function are two key factors of skeletal muscle function. However, the exact mechanism for coupling the two remains unknown. The genes encoding type I myosins Myh7/Myh7b regulate muscle fiber type switching by encoding their intronic miRNAs, miR-208b and miR-499. In a new study, Liu et al., 2016 use transgenic mice to show that miR-499 directly targets the gene encoding folliculin‐interacting protein‐1 (Fnip1), which negatively regulates AMPK. AMPK ........

Parental concerns about offspring autism: listen up!

by Paul Whiteley in Questioning Answers

"The developmental concerns expressed by parents of undiagnosed toddlers were highly consistent with the diagnosis the child later received."So said the findings reported by Megan Richards and colleagues [1] who continue a research theme suggesting that when it comes to 'developmental concerns' about offspring behaviour, parents are generally pretty good at spotting potential red flags and professionals should perhaps take further note.Based on data derived from "a toddler screening study" some ........

Can Dogs Understand Speech?

by Neuroskeptic in Neuroskeptic_Discover

A paper just published in Science has given rise to some astonishing headlines:
Dogs can understand human speech, scientists discover

Dogs process language like us

Dogs understand both words and intonation of human speech
But is the media's excitement justified, or are they barking up the wrong tree?



Here's the paper, from Hungarian neuroscientists Atilla Andics and colleagues. It was a canine fMRI study: dogs were trained to lie still in the MRI scanner and were played voice reco... Read more »

Trauma's epigenetic fingerprint observed in children of Holocaust survivors

by Dr. Jekyll in Lunatic Laboratories

The children of traumatized people have long been known to be at increased risk for posttraumatic stress disorder (PTSD), and mood and anxiety disorders. However, there are very few opportunities to examine biologic alterations in the context of a watershed trauma in exposed people and their adult children born after the event.

Cuttlefish Can Count to Five

by Elizabeth Preston in Inkfish



Don't look now, but this spineless sea creature may be able to count better than your toddler.

Cuttlefish need to be savvy if they want to eat. They're always on the lookout for shrimp, fish or crabs. When a cuttlefish spots a potential victim, it shoots out two specialized, sucker-bearing tentacles and nabs it. Since these hunters have to make constant judgments about which prey are worth targeting, it would make sense for them to have advanced cognitive skills—say, the ability to cou........

Music from Your Brain

by The Neurocritic in The Neurocritic

The journal Brain has a new review on the history of converting the electroencephalogram (EEG) into sound (Lutters & Koehler, 2016). The translation of data into sound, known as sonification, has been applied to brain waves since the 1930s. In addition to early scientific and medical applications, sonification of the EEG has been used in the field of experimental music.In 1965, physicist Edmond Dewan and composer Alvin Lucier collaborated on Music for the Solo Performer:Sitting on a cha........

Autism, optimal outcome and the broader autism phenotype

Scientists show that a 'Superman' disguise could actually work

In fact, researchers have shown that small alterations to a person's appearance, such as wearing glasses, can significantly hinder positive facial identification.

Brain Scans Show Your Dog Loves You And Food

by CAPB in Companion Animal Psychology Blog

An fMRI study shows different dogs have different preferences for food and social interaction.A recent fMRI study investigates individual differences in dogs’ preferences for food and social interaction with their owner. The results have been widely – and erroneously – reported as showing that dogs prefer praise to food. In fact, the results paint a far more interesting picture of how brain activity predicts canine choice.I think most people feel subjectively that their dog loves them. The........ Read more »

Why do we hate coriander?

by Alice Breda in la-Plumeria

In the morning you get up, trudge all the way to the sink, grab a bar of soap and rub it on your face. Sometimes, after you rinsed, you realize that some soap got into your mouth. The taste is nasty, pungent, more in your nose than on your tongue and it persists until you eat or drink something.

This sickening feeling doesn’t hit me only in my brightest mornings, but also every time in an ethnic restaurant or during a trip the cook decides to decorate my tacos or my curry with some chop........ Read more »
