Starting from the Beginning: Evolutionary and Developmental Origins of Human Knowledge

by Jason Goldman in The Thoughtful Animal

What are the cognitive and neural systems that allow us to build buildings, play checkers, do multivariate statistics, receive DVDs by mail, follow Dr. Isis's pesto recipe, or navigate the tangled LA freeways?

You may ask: what can studying children and non-human animals tell us about the complexity of the human experience? Only educated human adults engage with formal mathematics, cooking, or map reading. Right?

This is a reasonable question to ask. But when human adults show complex, possi........ Read more »

Individual Differences in Empathy

by Dr Shock in Dr Shock MD PhD


Empathy or the ability to appreciate someone else’s emotions and express this emotional awareness is a capacity that differs amongst individuals.
Cognitive empathy refers to imaginatively understanding another person’s thoughts, feelings and actions. Emotional empathy is feeling the emotion of another person, but maintaining a compassionate, other-focused perspective
Cognitive empathy can be tested with facial expression recognition. [...]

Binge Eating, Bulimia, and Reward Sensitivity

by Evil Monkey in Neurotopia

You all may remember that Sci's recent posts have focused on eating, overeating, and dopamine. Today, Sci continues this trend. Honestly, she couldn't stop thinking about it. How is overeating like addiction? How is it different? And so she began to look up a bunch of papers on binge eating and dopamine.

I was particularly interesting in the changes in food intake and reward associated responses in people with eating disorders like bulimia nervosa and anorexia nervosa. There are many hy........ Read more »

Samurai and Deep-Sea Loricifera Should Use More Rouge

He has not lived badly whose birth and death has been unnoticed by the world-Horace
It is good to carry some powered rouge in one’s sleeve. It may happen that when one is sobering up or waking from sleep, his complexion may be poor.  At such a time it is good to take out and apply [...]... Read more »

The Creativity-dopamine (b)linkage: more brains and bonkers connections

by sandygautam in The Mouse Trap






Image by jef safi via Flickr



Creativity is certainly different from intelligence; it is usually gauged as the ability to make novel and useful unique contributions to a field. Creativity itself is not a unified construct but can be broken into convergent creativity (involving more focused approach) and divergent creativity (involving more widening and loosening of More >Rating: 0.0/10 (0 votes cast)

Life in the trees, not bamboo, shaped the panda's "thumb"

by Laelaps in Laelaps



A red panda (Ailurus fulgens, left, photographed at the Bronx Zoo) and a giant panda (Ailuropoda melanoleuca, right, photographed at the National Zoo).




As the paleontologist Stephen Jay Gould so astutely pointed out in one of his most famous essays, the thumbs of giant pandas (Ailuropoda melanoleuca) are nothing at all like the large digits on our own hands. Their accessory "thumbs", visible on the surface as a differentiated part of the pad on the "palm" of the hand, are modified sesamoid........ Read more »

Take cisplatin in the morning and call me

by Michael Clarkson in Conformational Flux

Although we are most familiar with the circadian rhythm from its effects on our physiological state, the roots of the phenomenon lie in the molecular biology of individual cells. The circadian rhythm is the result of a transcriptional control system that regulates the levels of many different proteins in the cell with the passing of time. Not all of the proteins subject to this control have yet been catalogued, and as a result some surprising effects are still being discovered. A recent article ........ Read more »

Sensory Plasticity in Changing Environments

by Daniel Bassett in Chew the Fat

Can environmental conditions during early development shape individuals phenotypes so they become more adaptive to the conditions they are likely to encounter later in life? Such phenotypic plasticity could provide organisms with the potential to respond effectively to environmental change. One area where such plasticity would be important would be in an animals sensory capabilities. Animals extract information from the environment using a number of sensory systems, and this information guides t........ Read more »

Cottonmouth Moccasins: Adapting to the Beach and Beyond

by Johnny in Ecographica

Even though their preferred range places them in proximity to the Atlantic Ocean and the Gulf of Mexico, the conquest of marine ecosystems by the cottonmouths has been - as it has with most aquatically inclined reptiles - blockaded. The physiological demands of maintaining adequate hydration in a high-saline environment has constrained the Agkistrodon genus to a landward life. But things could change. ... Read more »

Poliovirus vaccine, SV40, and human cancer

by Vincent Racaniello in virology blog

Deep sequencing – which identified a viral contaminant of the rotavirus vaccine Rotarix - could have revealed the presence of simian virus 40 (SV40) in the poliovirus vaccine, had the technique been available in the 1950s. Exposure of over 100 million Americans to SV40, and many more worldwide, could have been avoided, as well as the debate [...]... Read more »

Children with Williams Syndrome don't form racial stereotypes

by Mo in Neurophilosophy

WILLIAMS Syndrome (WS) is a rare neurodevelopmental disorder caused by the deletion of about 28 genes from the long arm of chromosome 7. It is characterized by mild to moderate mental retardation and "elfin" facial features. Most strikingly, individuals with WS exhibit highly gregarious social behaviour: they approach strangers readily and indiscriminately, behaving as if everybody were their friend. And, according to a study published today in the journal Current Biology, they are the only know........ Read more »

Peer review: the neverending story

The Hunt for the Prozac Gene

by Neuroskeptic in Neuroskeptic

One of the difficulties doctors face when prescribing antidepressants is that they're unpredictable.One person might do well on a certain drug, but the next person might get no benefit from the exact same pills. Finding the right drug for each patient is often a matter of trying different ones until one works.So a genetic test to work out whether a certain drug will help a particular person would be really useful. Not to mention really profitable for whoever patented it. Three recent papers, pub........ Read more »

Health Behaviors More Important than Socioeconomic Status

by Shaheen Lakhan in Brain Blogger

Many studies have reported that socioeconomic status is a predictor of morbidity and mortality. Now, a large-scale, longitudinal study asserts that the association may be more related to health behaviors than socioeconomic status. The study, published in the Journal of the American Medical Association (JAMA), reports that assessment of health behaviors over time lessens the [...]... Read more »

Why (and How) People of a Feather Flock Together

by David Berreby in Mind Matters

Seeking the hidden causes of behavior, some scientists work on the scale of brain regions and neurons, searching inside people's heads. Others work on the scale of crowds, neighborhoods and nations, seeking hidden patterns in the way multitudes behave. What's unusual about this paper in PLoS One is that it combines both those perspectives: Mehdi Moussaïd and his co-authors have worked out the physical effects of a psychological motivation. That gave them a new way to predict how people wa........ Read more »
