Activity in lateral prefrontal cortex may improve emotion regulation in day-to-day life

Common wisdom tells us that for a successful relationship partners shouldn't go to bed angry. But new research from a psychologist at Harvard University suggests that brain activity-specifically in the region called the lateral prefrontal cortex-is a far better indicator of how someone will feel in the days following a fight with his or her partner.

Researchers discuss the synergy between nanoscience and neuroscience

Is it possible to build supercomputers that can replicate the human brain, or to develop nanotechnology that can lead to an implantable chip for interfacing with neurons and other types of cellular networks?

Transcendental Meditation technique produces unique state of "restful alertness"

A new EEG study conducted on college students at American University found they could more highly activate the default mode network, a suggested natural "ground state" of the brain, during their practice of the Transcendental Meditation technique. This three-month randomized control study is published in a special issue of Cognitive Processing dedicated to the Neuroscience of Meditation and Consciousness, Volume 11, Number 1, February, 2010.

Mood, behavioral problems after stressful interpersonal events: LPFC function may be a risk-factor

Think back to your last fight with someone you love. How did you feel afterwards? How did you behave? Conflict with a loved one often leaves a person feeling terrible and then behaving badly. So much so that these scenarios have become soap opera clich-s. After an argument, one partner may brood, slam the door, and then drive to a local bar to drown their sorrows in alcohol. These dramas rarely have happy endings. Given these stereotypes, how do people control their emotional reactions and prevent emotional storms and their attendant use of intoxicating substances?

Schizophrenia: Insight into late development of symptoms

In reports of two new studies, researchers led by Johns Hopkins say they have identified the mechanisms rooted in two anatomical brain abnormalities that may explain the onset of schizophrenia and the reason symptoms don't develop until young adulthood. Both types of anatomical glitches are influenced by a gene known as DISC1, whose mutant form was first identified in a Scottish family with a strong history of schizophrenia and related mental disorders. The findings could lead to new ways to treat, prevent or modify the disorder or its symptoms.

Study: People can reduce their sensitivity to pain by thickening their brain

People can reduce their sensitivity to pain by thickening their brain, according to a new study published in a special issue of the American Psychological Association journal, Emotion. Researchers from the Universit- de Montr-al made their discovery by comparing the grey matter thickness of Zen meditators and non-meditators.

Brain implant helps scientists in determining link between brainwave patterns and attention

A paralyzed patient implanted with a brain-computer interface device has allowed scientists to determine the relationship between brain waves and attention.

Recreational drugs can trigger memory lapse

Have you ever forgotten to post an important letter or let an appointment slip your mind? A new study from UK researchers suggests that for those who regularly use ecstasy or other recreational drugs, this kind of memory lapse is more common.

Siestas can dramatically boost and restore brain power

If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don't roll your eyes. New research from the University of California, Berkeley, shows that an hour's nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.

Calcium waves could be relevant for understanding the origin of Alzheimer's disease

New insights on what causes Alzheimer's disease could arise from a recent discovery made by bioengineers from the University of California, San Diego. The finding concerns the infamous amyloid beta peptides (Aβ)-fragments of which form plaques thought to play a role in Alzheimer's disease.

New research finds sensory cortex develops late in fragile X syndrome defect

Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch - even from their parents?

People with GAD have abnormalities in the way their brain unconsciously controls emotions

People with generalized anxiety disorder, or GAD, have abnormalities in the way their brain unconsciously controls emotions. That's the conclusion of a new Stanford University School of Medicine study, and the study authors say the findings could open up new avenues for treatments and change our understanding of how emotion is regulated in everyday life.

Findings could lead to new targeted therapies for speech and learning disabilities

A team of University of Oregon researchers have isolated an independent processing channel of synapses inside the brain's auditory cortex that deals specifically with shutting off sound processing at appropriate times.

Findings suggest AP patients lack the ability to process faces as a whole

In a new study published in the March 2010 issue of Elsevier's Cortex, researchers have found that the condition is linked to an inability to process faces as a whole, or holistically.

Brain researchers explore link between emotion and memory

In a novel study that used historical tape of a thrilling overtime basketball game between Duke and the University of North Carolina at Chapel Hill, brain researchers at Duke have found that fans remember the good things their team did much better than the bad.

Researchers explore how brain circuitry and learning changes over time

New research shows our brains are a lot more chaotic than previously thought, and that this might be a good thing. Neurobiologists at the University of Maryland have discovered information about how the brain processes sound that challenges previous understandings of the auditory cortex, which had suggested an organization based on precise neuronal maps.

Evidence suggests antidepressants may improve post-stroke recovery

Patients who received the antidepressant escitalopram following a stroke appeared to recover more of their thinking, learning and memory skills than those taking placebo or participating in problem-solving therapy, according to a report in the February issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Study assesses gray matter concentration deficits in multiple brain areas of people with OSA

A study in the Feb. 1 issue of the journal SLEEP found gray matter concentration deficits in multiple brain areas of people with severe obstructive sleep apnea (OSA). The study suggests that the memory impairment, cardiovascular disturbances, executive dysfunctions, and dysregulation of autonomic and respiratory control frequently observed in OSA patients may be related to morphological changes in brain structure.

UCLA's non-invasive pre-surgical testing approach leads to seizure-free surgical outcome in TSC patients

When medication fails to control seizures in children with tuberous sclerosis complex (TSC), a rare genetic disorder that affects multiple organ systems and frequently causes epilepsy, surgery to remove part of the brain is often necessary. But pre-surgical testing, which involves the implanting of electrodes into a child's head, can lead to longer hospital stays and greater risks from surgery.
