The brain's plasticity and its adaptability to new situations do not function the way researchers previously thought, according to a new study. Earlier theories are based on laboratory animals, but now researchers have studied the human brain, and reached some new conclusions.

Brain's response to threat silenced when we are reminded of being loved and cared for

Brain's response to threat silenced when we are reminded of being loved and cared for | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Being shown pictures of others being loved and cared for reduces the brain's response to threat, new research has found. The study discovered that when individuals are briefly presented pictures of others receiving emotional support and affection, the brain's threat monitor, the amygdala, subsequently does not respond to images showing threatening facial expressions or words. This occurred even if the person was not paying attention to the content of the first pictures.

Direct brain interface between humans

Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team's initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person's brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.

Liberal or conservative? Reactions to disgust are a dead giveaway

Liberal or conservative? Reactions to disgust are a dead giveaway | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
The way a person's brain responds to a single disgusting image is enough to reliably predict whether he or she identifies politically as liberal or conservative. As we approach Election Day, the researchers say that the findings come as a reminder of something we all know but probably don't always do: 'Think, don't just react.'

In a battle of brains, bigger isn't always better: Rats and mice perform similarly in cognitive tests

In a battle of brains, bigger isn't always better: Rats and mice perform similarly in cognitive tests | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
It's one of those ideas that seems to make perfect sense: the bigger the brain, the more intelligent the creature. Exceptions are becoming increasingly common, yet the belief persists even among scientists. Most biologists, for example, assume that rats are smarter than mice. Scientists now challenge this belief. They compared mice and rats and found very similar levels of intelligence, a result that could have powerful implications for researchers studying complex behaviors and learning.

People make immediate judgments about images they are shown, which could impact on their decisions, even before their brains have had time to consciously process the information, a study of brainwaves led by The University Of Melbourne has found.

Liberals are more emotion-driven than conservatives | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Researchers have studied the interaction between emotion and political ideology, showing that the motivating power of emotions is not the same for those on different ends of the ideological spectrum.

I still have large reservations about political findings in the brain.

Betting on brain research: Experts review challenges of translational neuroscience

Betting on brain research: Experts review challenges of translational neuroscience | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Despite great advances in understanding how the human brain works, psychiatric conditions, neurodegenerative disorders, and brain injuries are on the rise. Progress in the development of new diagnostic and treatment approaches appears to have stalled. Experts look at the challenges associated with 'translational neuroscience,' or efforts to bring advances in the lab to the patients who need them.

Researchers have been tracking the traces of implicit and explicit memories of fear in human. The study describes how in a context of fear, our brain differently encodes contextual memory of a negative event (the place, what we saw ...) and emotional response associated.

Brain anatomy differences between autistic, typically developing individuals are indistinguishable

Brain anatomy differences between autistic, typically developing individuals are indistinguishable | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
'Our findings offer definitive answers regarding several scientific controversies about brain anatomy, which have occupied autism research for the past 10 to 15 years,' says one expert. 'Previous hypotheses suggesting that autism is associated with larger intra-cranial gray matter, white matter and amygdala volumes, or smaller cerebellar, corpus callosum and hippocampus volumes were mostly refuted by this new study.'

Frontiers | Bayesian network analysis revealed the connectivity difference of the default mode network from the resting-state to task-state | Frontiers in Computational Neuroscience

Functional magnetic resonance imaging (fMRI) studies have converged to reveal the default mode network (DMN), a constellation of regions that display co-activation during resting-state but co-deactivation during attention-demanding tasks in the brain. Here, we employed a Bayesian network (BN) analysis method to construct a directed effective connectivity model of the DMN and compared the organizational architecture and interregional directed connections under both resting-state and task-state. The analysis results indicated that the DMN was consistently organized into two closely interacting subsystems in both resting-state and task-state. The directed connections between DMN regions changed significantly from the resting-state to task-state condition. These results suggest that the DMN intrinsically maintains a relatively stable structure whether at rest or performing tasks but has different information processing mechanisms under varied states.
