Eating green leafy vegetables keeps mental abilities sharp Something as easy as adding more spinach, kale, collards and mustard greens to your diet could help slow cognitive decline, according to new research. The study also examined the nutrients responsible for the effect, linking vitamin K consumption to slower cognitive decline for the first time. "Losing one's memory or cognitive abilities is one of the biggest fears for people as they get older," said Martha Clare Morris, Sc.D., assistant provost for community research at Rush University Medical Center and leader of the research team. "Since declining cognitive ability is central to Alzheimer's disease and dementias, increasing consumption of green leafy vegetables could offer a very simple, affordable and non-invasive way of potentially protecting your brain from Alzheimer's disease and dementia."
Your Memories Need Their Sleep Ann Whitman (212) email@example.com The big test is tomorrow—should you stay up late and study, or cut short the cram session and get a good night’s sleep? Most if not all students face this dilemma at some point in their lives. Until very recently, their choice might have seemed obvious: stay up and study, to commit as much information to memory as possible. To make memories, new neurons must erase older ones Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. That's the conclusion of a report in the November 13th issue of the journal Cell, a Cell Press publication, that provides some of the first evidence in mice and rats that new neurons sprouted in the hippocampus cause the decay of short-term fear memories in that brain region, without an overall memory loss. The researchers led by Kaoru Inokuchi of The University of Toyama in Japan say the discovery shows a more important role than many would have anticipated for the erasure of memories. They propose that the birth of new neurons promotes the gradual loss of memory traces from the hippocampus as those memories are transferred elsewhere in the brain for permanent storage. Although they examined this process only in the context of fear memory, Inokuchi says he "thinks all memories that are initially stored in the hippocampus are influenced by this process."
Daily Marijuana Use Doesn’t Really Change Brains of Adults or Teens, Study Finds Last year, the press and marijuana-legalization opponents gave a lot of attention to a study suggesting that daily marijuana causes abnormalities in the brain. New research, reportedly using better techniques, indicates that claim and other reports of cannabis-caused changes to brain structure simply aren't true. The authors of the new study, "Daily Marijuana Use Is Not Associated with Brain Morphometric Measures in Adolescents or Adults," published in the latest edition of the Journal of Neuroscience, suggest that alcohol use was responsible for previous studies finding brain changes. An abstract of the study's findings was published last week on the Journal's website. It describes how scientists could not replicate recent research that claimed the use of cannabis "is associated with volumetric and shape differences in subcortical structures..."
Explore - The Lab - Australian Broadcasting Corporation's Gateway to Science The Ancient Greeks and Romans and other ancient cultures placed great importance on memory, relying purely on memory to relate long speeches, epic poems, and engage in debates. Nowadays we may choose to keep the things we need to store in our memories on a range of portable devices – PDAs, calendars and diaries, laptop computers. But without our stored memories we would have no record of our personal lives. We would be unable to learn and would face life anew each day, like Drew Barrymore's character in the film 50 First Dates. We rely on our memory to help us move, tell us how to operate the many technical systems in the world around us, how to drive, catch buses, and what topics to talk about around the water cooler at work, in the canteen, or at school. How memories are stored
02.22.2010 - An afternoon nap markedly boosts the brain’s learning capacity 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. Students who napped (green column) did markedly better in memorizing tests than their no-nap counterparts.

Decoding spectrotemporal features of overt and covert speech from the human cortex Introduction Mental imagery produces experiences and neural activation patterns similar to actual perception. For instance, thinking of moving a limb activates the motor cortex, internal object visualization activates the visual cortex, with similar effects observed for each sensory modality (Roth et al., 1996; Kosslyn et al., 2001; Kosslyn, 2005; Stevenson and Case, 2005). Auditory imagery is defined as the mental representation of sound perception in the absence of external auditory stimulation. Behavioral and neural studies have suggested that structural and temporal properties of auditory features, such as pitch (Halpern, 1989), timbre (Pitt and Crowder, 1992; Halpern et al., 2004), loudness (Intons-Peterson, 1980) and rhythm (Halpern, 1988) are preserved during music imagery (Hubbard, 2013).

The Ten Most Revealing Psych Experiments Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble. That's something. 1.
Enrollment For Phase 3 Trial Evaluating Azeliragon in Treatment of Patients with Mild Alzheimer's Disease Enrollment of the first patients into STEADFAST (Single Trial Evaluating Alzheimer's Disease Following Addition to Symptomatic Therapy), vTv's Phase 3 placebo controlled trial of azeliragon, an oral antagonist of the Receptor for Advanced Glycation Endproducts (RAGE) for treatment of mild Alzheimer's disease has begun. Phase 3 begins following a Phase 2 trial that demonstrated positive results in slowing cognitive decline with 5 mg/day of azeliragon in patients with mild to moderate Alzheimer's Disease. STEADFAST is a randomized, double-blind, placebo-controlled Phase 3 study that is investigating the efficacy of Azeliragon as a potential disease modifying therapy for patients with mild Alzheimer's disease.
Develop Perfect Memory With the Memory Palace Technique The Memory Palace is one of the most powerful memory techniques I know. It’s not only effective, but also fun to use — and not hard to learn at all. The Memory Palace has been used since ancient Rome, and is responsible for some quite incredible memory feats. Eight-time world memory champion Dominic O’Brien, for instance, was able to memorize 54 decks of cards in sequence (that’s 2808 cards), viewing each card only once. And there are countless other similar achievements attributed to people using the Memory Palace technique or variations of it. Even in fiction, there are several references to the technique.
Tactile-Kinestheti Tactile-Kinesthetic Learners Making up about 5% of the population, tactile and kinesthetic learners absorb information best by doing, experiencing, touching, moving or being active in some way. Enjoy feeling, discovery and action Remember by using tools, building models and manipulating things Learn through emotions, touch, movement and space Enjoy demonstrations of concept demonstrations Master skills through imitation and practice. Use of vitamin E by patients with mild to moderate Alzheimer disease slows functional decline Among patients with mild to moderate Alzheimer disease, a daily dosage of 2,000 IUs of vitamin E, compared to placebo, was effective in slowing functional decline and in reducing caregiver time in assisting patients, according to a study appearing in the January 1 issue of JAMA. Alpha tocopherol, a fat-soluble vitamin (E) and antioxidant, has been studied in patients with moderately severe Alzheimer disease (AD) and in participants with mild cognitive impairment (MCI) but has not been studied in patients with mild to moderate AD. In patients with moderately severe AD, vitamin E was shown to be effective in slowing clinical progression. The drug memantine has been shown to be effective in patients with AD and moderately severe dementia, according to background information in the article. Maurice W.
Biofeedback Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and pain perception. Biofeedback may be used to improve health, performance, and the physiological changes that often occur in conjunction with changes to thoughts, emotions, and behavior. Eventually, these changes may be maintained without the use of extra equipment, even though no equipment is necessarily required to practice biofeedback. Biofeedback has been found to be effective for the treatment of headaches and migraines. Definition Sensor modalities
