But a new study suggests that heavy marijuana users may have some trouble letting go of negative emotions tied to memories — a phenomenon that's also seen in people with

Neuroscientists find first evidence animals can mentally replay past events: Discovery of episodic memory replay in rats could lead to better treatments for Alzheimer’s disease

Neuroscientists at Indiana University have reported the first evidence that non-human animals can mentally replay past events from memory. The discovery could help advance the development of new drugs to treat Alzheimer’s disease. The study, led by IU professor Jonathon Crystal, appears today in the journal Current Biology. “The reason we’re interested in animal memory

Putting distinct memories of similar events in their place

Neuroscientists have found new evidence on how distinct memories of similar events are represented in the brain. Its findings, which appear in the journal Neuron, correct a previous misconception of how such memories are stored in the hippocampus — a part of the brain crucial for memory and understanding space. “Previous research suggested that brain

Detecting Alzheimer’s disease before it’s too late: Intervention long before the first signs of memory issues may be required to slow disease progression

The rate at which the protein beta-amyloid accumulates into the sticky plaques associated with Alzheimer’s disease (AD) is already slowing by the time a patient would be considered to have preclinical AD, according to a longitudinal study of healthy adults published in JNeurosci. The research suggests that anti-amyloid therapies would be most effective before individuals

People expect their memory to fade as early as their 50s

People across the UK expect their memory to worsen in their 50s, according to new research from Heriot-Watt University. The results from the “What Keeps You Sharp?” survey, released today, reveals the majority of those asked believe lifestyle and genetics are equally important contributors to the changes they might experience. Almost nine out of 10
