New drug may protect against memory loss in Alzheimer’s disease

A new drug discovered through a research collaboration between the University at Buffalo and Tetra Therapeutics may protect against memory loss, nerve damage and other symptoms of Alzheimer’s disease. Preclinical research found that the drug—called BPN14770—deters the effects of amyloid beta, a hallmark protein of Alzheimer’s that is toxic to Continue Reading

‘Superagers’ over 80 have the memory and brain connectivity of twenty-somethings

Research published in the journal Cerebral Cortex has shown that stronger functional connectivity—that is, communication among neurons in various networks of the brain—is linked to youthful memory in older adults. Those with superior memories—called superagers—have the strongest connectivity. The work is the second in a series of three studies undertaken Continue Reading

Discovery of neuronal ensemble activities orchestrated to represent one memory

The brain stores memories through a neuronal ensemble, termed engram cells. A unique system was established to transfer neuronal population activity into light with discrimination between engram and non-engram cells using fluorescence proteins. By using this system, it is revealed that engram sub-ensembles represent distinct pieces of information, which are Continue Reading

Brain stem cells have a good memory

The cerebral cortex acts as the control centre of our cognitive processes. During embryogenesis, dozens of types of neurons with distinct functions come together to form the circuits that drive our thoughts and actions. These neurons are generated by progenitor cells, which produce them one after the other in a Continue Reading

Memory T cells shelter in bone marrow, boosting immunity in mice with restricted diets

Even when taking in fewer calories and nutrients, humans and other mammals usually remain protected against infectious diseases they have already encountered. This may be because memory T cells, which are located throughout the body and required to maintain immune responses to infectious agents, according to scientists at the National Continue Reading

Negative memory storage affects depression symptoms

Physical manifestations of negative memories in the hippocampus could underlie cognitive symptoms of depression, according to research in mice published in JNeurosci. Inhibiting these manifestations could be a future treatment route. Groups of neurons that are activated after an experience are thought to be the physical representation of memory. These Continue Reading

Effortless yet effective way of boosting memory performance revealed, works for both young students and Alzheimer’s patients

The human memory is a fragile and often misunderstood thing. It’s well-known that the brain is the organ that is largely responsible for its formation and consolidation, although there is clearly so much more to it that experts still need to learn. A new set of studies helps make sense of Continue Reading

THC from cannabis found to dramatically slow memory loss by protecting brain cells

Despite the Drug Enforcement Administration (DEA) still classifying marijuana as a schedule 1 drug (similar to heroin, ecstasy, LSD, and peyote), a new study confirms that the active compound in cannabis, tetrahydrocannabinol (THC), can benefit the elderly — particularly in preventing memory loss. Researchers from Germany studied THC’s effects on Continue Reading

Want to improve your memory or ability to concentrate? Lutein in avocados shown to boost eye and brain health

Eating avocados may help boost eye health, memory and attention, a study published in Nutrients revealed. A team of researchers at the Tufts University’s Jean Mayer USDA Human Nutrition Research Center on Aging noted that these beneficial effects were largely in part to the fruit’s high lutein levels. According to the experts, Continue Reading

Can’t trust your eyes or your memory? Maybe your brain cells are tired — new study shows being tired disrupts cellular communication in the brain

Do you ever find yourself out of sorts when you’ve had an all-nighter? If you’re often spacing out or if you’re suffering from eye strain, tired brain cells might be to blame. According to a recent study, which is the first of its kind, sleep deprivation can disrupt the brain Continue Reading

Chemo FAIL: Toxic chemotherapy found to impair memory, concentration, and brain function while having little or no long-term effect on cancer

A study carried out by researchers at the Aarhus University has revealed that chemotherapy affects brain network and impairs cognitive function. As part of the study, a team of health experts enrolled a total of 64 men who underwent testicular cancer surgery. The researchers noted that 22 of these men had chemotherapy following their operation, while Continue Reading
