Theta-band activity in hippocampus after an event seems to be crucial for learning. A study at the University of Jyväskylä also proved that the absence of theta facilitated learning a simple task while training during theta had no effect on learning.

MENLO PARK, Calif.—May 7, 2014—Neuroscientists at SRI International have found that a form of baclofen, a drug used to treat muscle spasticity, works better at treating narcolepsy than the best drug currently available when tested in mice.
According to the National Institute of Neurological Disorders and Stroke (NINDS), narcolepsy, a chronic neurologic disorder characterized by excessive daytime sleepiness, is not a rare condition, but is under-recognized and under-diagnosed. It is estimated to impact 1 in 2,000 people worldwide.
A recent study reported by Haigang Chang and co-workers from the First Affiliated Hospital of Xinxiang Medical University in China verified the effects of transient axonal glycoprotein-1 (TAG-1) on cell viability and p53, epidermal growth factor receptor (EGFR), and amyloid precursor protein (APP) intracellular C-terminal domain (AICD) expression in U251 glioma cells. Their pilot study showed that the signaling pathways induced by TAG-1, TAG-1/APP/AICD/p53 and TAG-1/APP/AICD/EGFR, did not inhibit glioma development by inhibiting cell proliferation or by inducing apoptosis.
Shuganjieyu capsule has been approved for clinical treatment by the State Food and Drug Administration of China since 2008. In the clinic, Shuganjieyu capsule is often used to treat mild to moderate depression. Prof. Jingping Zhao and team from the Second Xiangya Hospital, Central South University in China conducted a study to examine the effect of Shuganjieyu capsule on behavioral changes in a rat model of depression.
Emotions like fear, anger, sadness, and joy enable people to adjust to their environment and react flexibly to stress and strain and are vital for cognitive processes, physiological reactions, and social behaviour. The processing of emotions is closely linked to structures in the brain, i.e. to what is known as the limbic system. Within this system the amygdala plays a central role – above all it processes negative emotions like anxiety and fear. If the activity of the amygdala becomes unbalanced, depression and anxiety disorders may develop.
The effects of Amyloid beta (Aβ)-Aβ-binding alcohol dehydrogenase (ABAD) may exacerbate Alzheimer's disease pathology. Therefore, blocking Aβ-ABAD-mediate effects with ABAD decoy peptide (ABAD-DP) may be a potential therapeutic strategy for Alzheimer's disease. Dr. Jiang Wu and team from the First Hospital of Jilin University in China successfully constructed a recombinant adenovirus constitutively secreting and expressing Aβ-ABAD decoy peptide (rAAV/ABAD-DP-6His).
Amyloid-β (Aβ) plaques and neurofibrillary tangles are the main pathological hallmarks of Alzheimer's disease, as well as the loss of neurons and synapses. recent reports have shown that estrogen exerts neuroprotective effects. However, large clinical trials in postmenopausal women indicated adverse side-effects of estrogens, such as increased incidence of breast cancer and metrocarcinoma, thereby preventing clinical use of estrogen. Tongluojiunao (TLJN) is an herbal medicine consisting of two main components, geniposide and ginsenoside Rg1. Prof.
Scientists have been linking an increasing range of behaviors and inclinations from monogamy to addiction to animals', including humans', underlying biology. To that growing list, they're adding division of labor — at least in killer bees. A report published in ACS' Journal of Proteome Research presents new data that link the amounts of certain neuropeptides in these notorious bees' brains with their jobs inside and outside the hive.
Pregnant women show increased activity in the area of the brain related to emotional skills as they prepare to bond with their babies, according to a new study by scientists at Royal Holloway, University of London.
The research, which will be presented at the British Psychological Society's annual conference on Wednesday 7 May, found that pregnant women use the right side of their brain more than new mothers do when they look at faces with emotive expressions.
PULLMAN, Wash.—It sounds like a phrase from Urban Dictionary, or the title of an animated gif, but a Washington State University researcher says "exploding head syndrome" is an authentic and largely overlooked phenomenon that warrants a deeper look.
More than a million people are treated for mild traumatic brain injuries in U.S. hospitals and emergency rooms each year. Yet few receive appropriate psychological and social follow-up care that can make the difference in whether or not they fully recover.
A University of Washington researcher has found that a 20-minute conversation with a social worker has the potential to significantly reduce the functional decline of those diagnosed with a mild traumatic brain injury.
The research is published in the April issue of Brain Injury.
Automation in the cockpit is traditionally believed to free pilots' attention from mundane flight tasks and allow them to focus on the big picture or prepare for any unexpected events during flight. However, a new study published in Human Factors indicates that pilots may have a hard time concentrating on the automated systems that now carry out many of the tasks once completed by humans.
(Boston) – Have you ever said to yourself that you would only have a handful of potato chips from the bag then, minutes later, realized you ate the whole thing? A recent study shows that this type of impulsive behavior might not be easily controlled – and could be a risk factor in the development of food addiction and eating disorders as a result of cellular activities in the part of the brain involved with reward.
COLUMBUS, Ohio – Concussion rates in U.S. high-school athletes more than doubled between 2005 and 2012, according to a new national study using data on nine team sports.
Overall, the rate increased from .23 to .51 concussions per 1,000 athlete exposures. An athlete exposure is defined as one athlete participating in one competition or practice.
Britain could become a nation of non-swimmers if drastic changes aren't made to ensure all young people have access to adequate lessons and facilities, according to academics at the University of East Anglia (UEA).
