Remembering to Forget →
neurosciencestuff:
New research suggests that it is possible to suppress emotional autobiographical memories. The study published this month by psychologists at the University of St Andrews reveals that individuals can be trained to forget particular details associated with emotional memories.
The important findings may offer exciting new potential for therapeutic interventions for individuals...

Scientists discover how the brain encodes memories... →
metaconscious:
“When we learn new things, when we store memories, there are a number of things that have to happen,” said senior author Kenneth S. Kosik, co-director and Harriman Chair in Neuroscience Research, at UCSB’s Neuroscience Research Institute. Kosik is a leading researcher in the area of Alzheimer’s disease.
“One of the most important processes is that the synapses — which cement...

The Humans With Super Human Vision →
fuckyeahneuroscience:
An unknown number of women may perceive
millions of colors invisible to the rest of us. One British scientist is trying to track them down and understand their extraordinary power of sight.
An average human, utterly unremarkable in every way, can
perceive a million different colors. Vermilion, puce, cerulean, periwinkle, chartreuse—we have thousands of words for them, but...

Brain correlates of resting, alert, and meditation... →
neuroticthought:
Posner and colleagues do a nice review of neural correlates of establishing, maintaining, and switching brain states. I thought I would pass on a few chunks from their article describing the alert state and the meditation state:
The three brain states are compared in Table 1.
The meditation state differs from the alert state induced by a warning signal in several crucial...

Boost Creativity: 7 Unusual Psychological... →
metaconscious:
Looking for the last piece of the puzzle? Try these 7 research-based techniques for increasing creativity.
Everyone is creative: we can all innovate given time, freedom, autonomy, experience to draw on, perhaps a role model to emulate and the motivation to get on with it.
But there are times when even the most creative person gets bored, starts going round in circles, or hits a...

Chinese mindfulness meditation prompts double... →
neuroticthought:
Scientists studying the Chinese mindfulness meditation known as integrative body-mind training (IBMT) say they’ve confirmed and expanded their findings on changes in structural efficiency of white matter in the brain that can be related to positive behavioral changes in subjects practicing the technique regularly for a month.
In a paper appearing this week in the online Early...

neuroticthought:
When we say “I knew him way back when,” or “the best years are still ahead of you,” we’re using space to set up a timeline, with the past trailing behind us and the future stretching forward. Scientists long assumed that all people envisioned time that same way. But more recent studies have shown that’s not the case: Mandarin Chinese speakers may refer to the past as above...

Social influences on neuroplasticity: stress and... →
Experiential factors shape the neural circuits underlying social and emotional behavior from the prenatal period to the end of life. These factors include both incidental influences, such as early adversity, and intentional influences that can be produced in humans through specific interventions designed to promote prosocial behavior and well-being. Here we review important extant evidence in...

Hyperscanning →
neuroticthought:
A couple of years back I looked at a paper by G. Dumas etal. (here) and was impressed. Recently he commented on a posting. This prompted me to look at the recent work of the group. They have developed a method that allows them to look at the interaction between two brains in communication and advance from individual to social theories of cognition.
Two people communicate with...

Hands-on research: Neuroscientists show how brain... →
neurosciencestuff:
A nuzzle of the neck, a stroke of the wrist, a brush of the knee—these caresses often signal a loving touch, but can also feel highly aversive, depending on who is delivering the touch, and to whom. Interested in how the brain makes connections between touch and emotion, neuroscientists at the California Institute of Technology (Caltech) have discovered that the association...

“To be perfectly original one should think much and read little, and this is...”
– Lord Byron, on the paradox of being original and combining previous influences. A crisis of any creator, artistic or scientific.
Maria Popova assembles a masterful collection of advice to reconcile this paradox: The Art of Scientific Investigation (1957), Part I: The Role of Openness and...

neurosciencestuff:
Neuroscientists at Cold Spring Harbor Laboratory (CSHL) just reached an important milestone, publicly releasing the first installment of data from the 500 terabytes so far collected in their pathbreaking project to construct the first whole-brain wiring diagram of a vertebrate brain, that of the mouse.
Composite image generated with Mouse Brain Architecture project data....

houseofmind:
The day has finally come- I’m finally published and second author on a publication! Most of this work was done as part of my rotation project during my first year in graduate school. These findings (particularly the social behavior data) were my intellectual and technical contribution to the project and they laid the foundation for the NSF GRFP that I wrote in 2010 and was awarded...

The Age of Olfactory Bulb Neurons in Humans |... →
Continuous turnover of neurons in the olfactory bulb is implicated in several key aspects of olfaction. There is a dramatic decline postnatally in the number of migratory neuroblasts en route to the olfactory bulb in humans, and it has been unclear to what extent the small number of neuroblasts at later stages contributes new neurons to the olfactory bulb. We have assessed the age of olfactory...
