New findings of cortical activity during delta wave sleep sheds further light into memory formation

Scientists at the Center for Interdisciplinary Research in Biology have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an essential role in long-term memory formation. These …

Effects of flu on brain

Group of researchers from Germany and USA studied effects of influenza virus on brain cells. The study published in the Journal of Neuroscience finds that female mice infected with two different strains of the flu shows changes in structure and function of the hippocampus. These changes persist for one month after infection. The long-term effect …

Research shows musicians have faster reaction to sensory stimuli

According to a new study by Université de Montréal’s School of Speech-Language Pathology and Audiology, part of UdeM’s medical faculty learning to play musical instrument help elderly to react faster and to stay alerted. The study is published in journal Brain and Cognition.  The study shows that musicians have faster reaction times to sensory stimuli than …

Biomarker Autotaxin, related to diabetes predicts Alzheimer’s disease outcome

An enzyme found in the fluid around the brain and spine is giving researchers a snapshot of what happens inside the minds of Alzheimer’s patients and how that relates to cognitive decline. Iowa State University researchers say higher levels of the enzyme, autotaxin, significantly predict memory impairment and Type 2 diabetes.  Autotaxin often studied in …

Exercise improves memory in Diabetic rats

University of Tsukuba led researchers shows that moderate exercise may improve hippocampal memory dysfunction caused by type 2 diabetes and that enhanced transport of lactate to neurons may be the underlying mechanism. Type 2 diabetes is characterized by impaired glucose metabolism and can cause central nervous system-related complications, such as memory dysfunction. The hippocampus is …
