Using focused magnetic stimulation of brain to improve precision memory

Northwestern Medicine scientists showed for the first time that non-invasive brain stimulation can be used like a scalpel, rather than like a hammer, to cause a specific improvement in precise memory. This is an individual receiving noninvasive brain stimulation (‘high-frequency, repetitive, transcranial electromagnetic stimulation’). Credit: Northwestern University  Precise memory, rather than general memory, is critical …

Stress, cortisol and perceptual learning process

Neuroscientists of the Ruhr University Bochum found that stress has adverse impact on our learning process. Usually when we train our senses, we sharpen them and thereby improve our perceptual performance. However during stressful situations we produce a hormone called cortisol, which completely blocks this important ability. These findings are reported in Journal “Psychoneuroendocrinology”  Stress …

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 …

Role of Hippocampus in future thinking and scene construction

Over the past decade, researchers have learned that the hippocampus historically known for its role in forming memories is involved in much more than just remembering the past; it plays an important role in imagining events in the future. Yet, scientists still do not know precisely how the hippocampus contributes to episodic imagining until now. …

Research shows new understanding on how working memory is stored in brain

Working memory is integral part of  cognitive process and it involves short term memory. Previous research shown that  it depends on sustained, elevated brain activity. However researchers at University of Wisconsin-Madison have shown that humans can hold information in working memory via “activity-silent” synaptic mechanisms. Their study is published in journal Science. According to Brad Postle, …
