‘Frenemy’ in Parkinson’s disease takes to crowdsourcing

‘Frenemy’ in Parkinson’s disease takes to crowdsourcing

The protein alpha-synuclein is a well-known player in Parkinson’s disease and other related neurological conditions, such as dementia with Lewy bodies. Continue reading

Brain chemical potential new hope in controlling Tourette Syndrome tics

Brain chemical potential new hope in controlling Tourette Syndrome tics

A chemical in the brain plays a vital role in controlling the involuntary movements and vocal tics associated with Tourette Syndrome (TS), a new study has shown. Continue reading

How physical exercise protects the brain from stress-induced depression

How physical exercise protects the brain from stress-induced depression

Physical exercise has many beneficial effects on human health, including the protection from stress-induced depression. However, until now the mechanisms that mediate this protective effect have been unknown Continue reading

Dying brain cells cue new brain cells to grow in songbird

Dying brain cells cue new brain cells to grow in songbird

Brain cells that multiply to help birds sing their best during breeding season are known to die back naturally later in the year. For the first time researchers have described the series of events that cues new neuron growth each spring, and it all appears to start with a signal from the expiring cells the previous fall that primes the brain to start producing stem cells. If scientists can further tap into the process and understand how those signals work, it might lead to ways to exploit these signals and encourage replacement of cells in human brains that have lost neurons naturally because of aging, severe depression or Alzheimer’s disease, said Tracy Larson, a University of Washington doctoral student in biology Continue reading

Statin use during hospitalization for hemorrhagic stroke associated with improved survival

Statin use during hospitalization for hemorrhagic stroke associated with improved survival

Patients who were treated with a statin in the hospital after suffering from a hemorrhagic stroke were significantly more likely to survive than those who were not, according to a study published today in JAMA Neurology . This study was conducted by the same researchers who recently discovered that the use of cholesterol-lowering statins can improve survival in victims of ischemic stroke. Ischemic stroke is caused by a constriction or obstruction of a blood vessel that blocks blood from reaching areas of the brain, while hemorrhagic stroke, also known as intracerebral hemorrhage, is bleeding in the brain Continue reading

Food Memory: New discovery outlines how we remember taste experiences

Food Memory: New discovery outlines how we remember taste experiences

Have you ever eaten something totally new and it made you sick? Don’t give up; if you try the same food in a different place, your brain will be more “forgiving” of the new attempt Continue reading

Sensing neuronal activity with light

Sensing neuronal activity with light

For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain’s circuitry in action — from the first moment a neuron fires to the resulting behavior in a whole organism. To get this complete picture, neuroscientists are working to develop a range of new tools to study the brain. Continue reading

Zebrafish Model of a Learning and Memory Disorder Shows Better Way to Target Treatment

Zebrafish Model of a Learning and Memory Disorder Shows Better Way to Target Treatment

Using a zebrafish model of a human genetic disease called neurofibromatosis (NF1), a team from the Perelman School of Medicine at the University of Pennsylvania has found that the learning and memory components of the disorder are distinct features that will likely need different treatment approaches. They published their results this month in Cell Reports . Continue reading

Brain inflammation dramatically disrupts memory retrieval networks, study finds

Brain inflammation dramatically disrupts memory retrieval networks, study finds

Brain inflammation can rapidly disrupt our ability to retrieve complex memories of similar but distinct experiences, according to UC Irvine neuroscientists Jennifer Czerniawski and John Guzowski. Continue reading

Multiple sclerosis researchers find role for working memory in cognitive reserve

Multiple sclerosis researchers find role for working memory in cognitive reserve

Kessler Foundation scientists have shown that working memory may be an underlying mechanism of cognitive reserve in multiple sclerosis (MS). This finding informs the relationships between working memory, intellectual enrichment (the proxy measure for cognitive reserve) and long-term memory in this population. “Working memory mediates the relationship between intellectual enrichment and long-term memory in multiple sclerosis: An exploratory analysis of cognitive reserve”  was published online ahead of print by the Journal of the International Neuropsychological Society on July 14.
