Memory Depends On Protein ‘Off Switch”

 A new study suggests a lack of cognitive flexibility and ability to retain new information may be a result of the Arc protein not being fully switched off. Memory, learning and cognitive flexibility depend on a protein ‘off-switch’ in the brain, according to a breakthrough discovery made by an international research collaboration co-led by the University of Warwick. This new knowledge could enable us to better understand and combat neurological …Read More

Brain Size in Bipolar Disorder

New study on how the hippocampus is diminished in size with bipolar disorder. In people with schizophrenia, the hippocampus, a part of the brain involved in memory and emotion, tends to shrink. Scientists have wondered whether this is also the case in mood disorders. Now, a team led by NARSAD 2016 Young Investigator Bo Cao, Ph.D., at the University of Texas Health Science Center at Houston, have taken a closer look at the hippocampus in people with mood disorders, …Read More

Dual Diagnosis of Schizophrenia and Substance Use Disorder

By the Brain & Behavior(link is external) Research Staff Several new genome-wide investigations of schizophrenia and substance-use disorders are helping researchers understand how these two conditions may be related, according to a paper published in Genome Medicine. People with schizophrenia are more likely than those without the disease to smoke or to heavily use alcohol and recreational drugs, contributing to their higher death and disability rates. By comparing the genetic underpinnings of schizophrenia and substance-use disorder, scientists may be able to …Read More

Untangling the Brain’s Complexity

Hundreds of billions of neurons connect with one another in the human brain—each one specialized for a particular role in the communication network. There are probably hundreds or maybe even thousands of specific types of neurons in the brain, displaying a bewildering array of shapes, sizes, and biological properties. New research reported September 21 in the journal Cell will help neuroscientists make sense of this astonishingly diverse range of cells. According to the …Read More

Transcranial Magnetic Stimulation for Resistant Depression

Repetitive Transcranial Magnetic Stimulation (rTMS), a therapy in which electromagnetic fields are pulsed through a coil placed on the scalp, can produce antidepressant effects in individuals who are resistant to or unable to tolerate standard antidepressant drugs. Now, a new study published in the journal BrainStimulation suggests that a new means of delivering rTMS, a “two-coil array,” can be safely used and may help to stimulate deeper areas of the brain than the current single-coil designs. The …Read More

3 Ways to Declutter Your Mind

Researchers estimate you have about 60,000 thoughts each day. And many of those thoughts involve thinking the same things over and over again. I never have enough time. I have nothing to wear. I look stupid. My house isn’t clean enough. My life would be better if I had more money. Rehashing the same things, focusing on the negative, and worrying about things you can’t control wastes your time and your …Read More

Activation-Synthesis Model of Dreaming

The activation-synthesis theory is a neurobiological explanation of why we dream. The question of why people dream has perplexed philosophers and scientists for thousands of years, but it is only fairly recently in history that researchers have been able to take a closer look at exactly what happens in the body and brain during dreaming. Harvard psychiatrists J. Allan Hobson and Robert McCarley first proposed their theory in 1977, suggesting that dreaming results …Read More

The 10 Percent of Brain Myth

The human brain is complex and still quite mysterious. It is perhaps for this reason why so many myths about how the brain works persist, despite plenty of evidence to the contrary. One of the most common of these myths is often referred to as the ten percent of brain myth, or the idea that human being really only fully utilize a tiny percentage of their brain’s power and potential. The popularly and widely …Read More

The Effects of Smartphones on the Brain

Effects of Smartphones On the Brain Recent research suggests that smartphone usage does indeed have an effect on the brain, although the long-term effects remain to be seen. In one studypresented to the Radiological Society of North America, researchers found that young people with a so-called internet and smartphone addition actually demonstrated imbalances in brain chemistry compared to a control group. Another studying appearing in the Journal of the Association for Consumer Research found …Read More

Which Careers Are Best for Your Brain?

ould what you do for a living have an influence on your mental acuity and acumen as you age? According to the results of one study, careers that involve more mental complexity may help protect your brain from cognitive declines as you age. People with mentally demanding jobs such as surgeons, lawyers, civil engineers, and graphic designers may have better memory in old-age, the study indicated. Factors That Influence Your “Cognitive Reserve” …Read More
