Are there two types of cognition?

by Janet Kwasniak in Thoughts on thoughts


J. Evans’ 2008 paper reviews a number of proposed dual-processing descriptions of cognition. (see citation). He finds some stable divisions in the theories but a number of conflicting ones also. Calling the dual processing system 1 and system 2 appears to him to give a mistaken impression of how cognition works; he feels that [...]... Read more »

Reading the mind’s eye: Online detection of visuo-spatial working memory and visual imagery in the inferior temporal lobe

by Julien Colomb in neuro JC

Posted on behalf of Jaime Martinez:
The authors of the present work studied the extent to which visual brain regions participate in non-sensory cognitive processes of visual representation. To this end, they evaluated the role of ventral visual pathway areas in visual imagery and working memory by analyzing intracerebral EEG recordings from the left inferior temporal [...]...

Epidemiology of Brain Cancer

by William Yates, M.D. in Brain Posts

A recent summary of the trends in cancer highlighted the epidemiology of brain and other nervous system tumors.  In the United States, 213,500 brain and other nervous system tumors were diagnosed during the four year period from 2004 through 2007.Brain and other nervous systems (ONS) tumors rank fourteenth in the top 15 cancers for men and fifteenth in the top 15 cancers for women in the United States.Overall rates for brain and ONS tumors during this period were 22.37 per 100,000 for men a........

Taking the sacred path to decision making

by Andrew Watt in A Hippo on Campus

They say that when in polite company one should never discuss religion or politics. An old adage which is perhaps even more pertinent when you find yourself dining with boors. After all there are few topics of conversation with the innate ability to turn a soiree into a shouting match as those we hold sacred. Whether it be our views on life or what follows afterwards, there's just something about those consecrated concepts that doesn't allow any room for compromise. But what is about these funda........

The Whole Enchilada: New Method for High-Res Brain Images

by Karen Kreeger in Penn Medicine News Blog

Magnetic resonance imaging (MRI) provides exquisite structural detail of the brain, for example, to detect tumors or relative size of regions. However, current MRI methods are not capable of imaging the distribution of neurotransmitters – the brain’s chemical messengers -- across the whole brain. A new Nature Medicine paper out this week from Perelman School of Medicine researchers led by Ravinder Reddy, PhD, professor of Radiology, describes a first-of-its-kind MRI technique (GluCEST) to me........

Are Wallabies Left or Right Handed? Both! (Sometimes)

by Jason Goldman in The Thoughtful Animal

Which limb do you prefer? If you’re like most members of our species, you prefer your right hand for most tasks. If you’re like a smaller minority of our species, you might prefer your left hand. Very, very few of us are truly ambidextrous. Most of us have at least a minor preference for one [...]

The "Human Neuron", not so special after all?

by TheCellularScale in The Cellular Scale

Von Economo neurons, a set of neurons classified by their elongated, 'spindle-like' shape, were once thought to belong only to humans and great apes. This uniqueness, as you might imagine, encouraged extensive speculation about what this neuron does.  Do they make you smart? Do they process emotions? social cues? future planning?Not that extensive speculation is a bad thing, it's just that it is easy to jump into the deep end and assume that because something is unique to humans, it is what........

IQ Varies with Context

by Greg Laden in Greg Laden's Blog

In a very interesting way.

As a regular reader of this blog, you know that IQ and similar measures are determined by a number of factors, and for most "normal" (modal?) individuals, one's heritage (genes) is rarely important. Putting it another way, variation across individuals in IQ and other measures have been shown again and again to be determined by things like home environment, diet and nutrition, and even immediate social context. Here's another finding supporting this: Read the rest o........ Read more »

An Epilogue to a Protein Saga – But Not the Last Word

by Karen Kreeger in Penn Medicine News Blog

Every saga needs occasional updates. TDP-43 -- a protein important in gene expression that can undergo pathologic misfolding -- is no different. Earlier reports on the protein were outlined in a Penn Med news blog, which describes its pathology and genetics related to neurodegenerative disease. But now the field is maturing and researchers are linking TDP-43 to a well-established clinical area - the role of oxidative stress in the demise of nerve cells.

Males have bigger brains than females, if those males are sticklebacks from Iceland

by Zen Faulkes in NeuroDojo

This supershort paper contains an interesting fact: there is a population of male stickleback fish out there with big brains. The males fish that have brains 23% larger than the females of approximately equal size.

This is a bit of an unfair characterization. The paper does talk a little bit about how the look for differences in brain size according to the local eco-type that they found the fish and: mud or lava. the nails from allow the environments have bigger brains than those from muddy env........

fMRIs and Persuasion: Did anyone tell the jurors?

by Rita Handrich in The Jury Room

We all know that neuro-imaging is not ready for courtroom persuasion yet, but did someone remember to tell the jurors? Apparently not–but maybe they already knew. Are “pictures” of the brain so persuasive that they can sway juror decision making? Even though the credibility of the medical experts has to be factored in, many people believe [...]

The Hidden Face Within

by Neuroskeptic in Neuroskeptic

One of these two images contains a hidden picture of a face. Which one?This was the question faced by participants in a remarkable psychology experiment just published, Measuring Internal Representations from Behavioral and Brain Data. Five healthy volunteers were presented with a series of random black and white grid patterns. Each grid square was either black or white, and this was randomly determined on each trial.There was no pattern to the images, they were completely random. But the subjec........ Read more »

Parent Training and Conduct Disorder Outcome

by William Yates, M.D. in Brain Posts

Three previous posts examined the clinical neuroscience disorder antisocial personality disorder (ASPD).  This condition results in high societal costs for crime and incarceration for individuals with ASPD.ASPD appears to have significant genetic contributions and brain imaging studies show abnormal brain maturational patterns in the premotor cortex area as well as impaired processing of facial emotional expression.Antisocial personality is an early age of onset disorder with conduct disord........
