BBC News - Dream recording device 'possible'... →
fuckyeahneuroscience:
A US researcher says he plans to electronically record and interpret dreams.
Writing in the journal Nature, scientists say they have developed a system capable of recording higher level brain activity.
He admits that there is a very long way to go before this simple observation can be translated into a device to record dreams, or dream catcher. But he thinks it is a...

Fitting two languages into one brain — Brain: A... →
The co-existence of multiple languages in the same brain suggests that sophisticated mechanisms of segregation and coordination must exist to prevent cross-talk. In this issue, Cathy Price, David Green and Roswitha von Studnitz use positron emission tomography to throw some light on bilinguals’ cerebral organization (Price et al., 1999). Their results clarify how bilingual brains escape the...

Emotion and its disorders: Imaging in clinical... →
In humans, feeling-states and subjective emotional experiences reflect cognitive contextual awareness of emotional responses and may be embellished into secondary emotions, such as guilt or relief. This review addresses the application of neuroimaging techniques to understanding the neural mechanisms supporting these aspects of emotional experience.

The bilingual brain as revealed by functional... →
Neuroimaging studies of bilinguals and polyglots have highlighted the potential role of variables, such as age of acquisition, degree of proficiency, level of exposure, dominance/maternality on functional brain mapping of multiple languages.

Feeling Sad Makes Us More Creative →
jtotheizzoe:
Could this have anything to do with how Ph.D. students find their inspiration? Eh?
“What’s driving this correlation? Why does a melancholy mood turn us into a better artist? The answer returns us to the intertwined nature of emotion and cognition. It turns out that states of sadness make us more attentive and detail oriented.”

Love Makes You Increasingly Ignorant of Your... →
psychotherapy:
Long-lasting marriages may thrive on love, compromise and increasing ignorance about one another. Couples married for an average of 40 years know less about one another’s food, movie and kitchen-design preferences than do partners who have been married or in committed relationships for a year or two, a new study finds.
Two University of Basel psychologists, Benjamin Scheibehenne...

Are the mentally ill more creative? →
Research evidence supports the notion that dopaminergic neurotransmission plays a role in creative thought and behavior. A group of researchers in Sweden investigated the relationship between creativity, as indexed by divergent thinking (the ability to generate many novel ideas by exploring a multitude of options), and dopamine receptor expression in the brain because divergent thinking is...

Hidden Pleasure: The Science of Why We Like What...
Let’s say your favorite wine is an Alexander Valley cabernet. Why do you enjoy it so much? A wine expert might cite its rich texture, hints of cherry and floral aroma. The casual drinker might say he or she just likes its taste. And both are probably wrong, or at least deceiving themselves.
What you like about the wine is something that goes deeper than either its objective descriptions or...

Neurolinguistics: Structural plasticity in the... →
Humans have a unique ability to learn more than one language — a skill that is thought to be mediated by functional (rather than structural) plastic changes in the brain1. Here we show that learning a second language increases the density of grey matter in the left inferior parietal cortex and that the degree of structural reorganization in this region is modulated by the proficiency attained...

Picking Our Brains . Nine Neural Frontiers →
The human brain is the most astoundingly complex structure in the known universe. Yet we are starting to unravel some of its mysteries, thanks to advances in brain imaging, genetics, stem cell research and more. We explore the latest findings from the hottest topics in neuroscience.
01. What are memories made of?
02. Will we ever be able to regenerate the brain?
03. What are mirror neurons?...

The Sound of Neurons →
“They emit electrical signals of around 40 hertz, which sound like a buzzing, irritating noise played back as audio files. I used some specialist software to distinguish the signal within the noise - and to produce sound from within each peak that is closer to the frequency of a human voice and therefore more revealing to the ear.
Listening to the results reprocessed at around...

iamziyad:
Every evening our eyes tell us that the sun sets, while we know that, in fact, the Earth is turning us away from it. Astronomy taught us centuries ago that common sense is not a reliable guide to reality. Today it is neuroscience that is forcing us to readjust our intuitions. People naturally believe in the Ghost in the Machine: that we have bodies made of matter and spirits made...
