Dreamed Movement in Lucid Dreamers Elicits... →
neuroticthought:
Dresler et al. are doing fascinating research on dreaming at the Max Planck Institute of Psychiatry.
Due to the impossibility of experimentally controlling spontaneous dream activity a direct demonstration of dream contents by neuroimaging methods is lacking. By combining brain imaging with polysomnography and exploiting the state of “lucid dreaming,” we show here that a...

neuroticthought:
by Jordan Gaines
Even the most rational of us experience it: you’ll be chatting with friends or exploring a place you’ve never been when suddenly a feeling washes over you: you’ve experienced this exact moment before. The familiarity is overwhelming, and it shouldn’t be familiar at all. The sensation becomes stronger before ebbing, then completely leaves, all within a matter of...

neuroticthought:
by Janet Kwasniak
Christopher Bergland (here) believes that we think in a different way when we exercise.
Anyone who exercises regularly knows that your thinking process changes when you are walking, jogging, biking, swimming, riding the elliptical trainer, etc. New ideas tend to bubble up and crystallize when you are inside the aerobic zone. You are able to connect the...

An Off Switch for Pain: Chemists build... →

February 22nd, 2012
The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the...

February 14th, 2012
Humans move between ‘patches’ in their memory using the same strategy as bees flitting between flowers for pollen or birds searching among bushes for berries.
Researchers at the University of Warwick and Indiana University have identified parallels between animals looking for food in the wild and humans searching for items within their memory –...

Memory Interference →
neuroticthought:
Here’s a very interesting study done by Malberg et al. who investigated recall interference on 88 undergrads at Indiana University:
A large group of words are assembled into four categories. Participants are briefly shown these words randomly, one at a time. After this ‘study period’, the participants are given 150 self-paced trials of two words - one from the original study...

psychotherapy:
So are most marriages doomed to fail?
It is an archaic institution designed to expire concurrent with a woman’s childbearing years, just like in the olden days. The idea of two people changing together and—more importantly— accepting each others changes over a 50-year span is delusional unless that person is undeniably your best friend in the whole world. Ever.
Needs-based...

fuckyeahneuroscience:
Short-term memory requires communication between multiple brain regions that collectively mediate the encoding and maintenance of sensory information. It has been suggested that oscillatory synchronization underlies intercortical communication. Yet, whether and how distant cortical areas cooperate during visual memory remains elusive. We examined neural interactions...

Neuromarketers are using MRI scanners and electrode caps to work out our hidden reactions to their adverts
The world’s biggest companies have got a new way of convincing you to buy their products – by getting inside your head. Brands including Google, Facebook and ITV are turning to mind-reading technology to help them develop products and create adverts that people like.

neuroticthought:
Here’s an interesting article studying the difference in brain activity between imagining and experiencing the same object.
Several brain regions involved in visual perception have been shown to also participate in non-sensory cognitive processes of visual representations. Here we studied the role of ventral visual pathway areas in visual imagery and working memory. We...

Hearing metaphors activates brain regions involved... →
Linguists and psychologists have debated how much the parts of the brain that mediate direct sensory experience are involved in understanding metaphors. George Lakoff and Mark Johnson, in their landmark work ‘Metaphors we live by’, pointed out that our daily language is full of metaphors, some of which are so familiar (like “rough day”) that they may not seem especially novel or striking. They...

Computational models decode and reconstruct neural responses to speech.
The brain’s electrical activity can be decoded to reconstruct which words a person is hearing, researchers report today in PLoS Biology1.
Brian Pasley, a neuroscientist at the University of California, Berkeley, and his colleagues recorded the brain activity of 15 people who were undergoing evaluation...
