Researchers propose that Parkinson’s disease may start in the gut, not the brain
Scientists propose that Parkinson’s disease may begin far from the brain, where environmental toxins, microbiome disruption, and intestinal…
Scientists put forward a new theory of brain development
Your brain begins as a single cell. When all is said and done, it will house an incredibly…
ATP delivery fixes dysfunctional dopamine packaging in Parkinson’s neurons
A new study shows how dysfunctional packaging of the neurotransmitter dopamine triggers toxic processes in neurons – and…
NIH’s continued investment fuels TMJ pain research
Chronic pain is one of the most common health conditions worldwide. Back pain is the most frequently reported…
Study identifies PPP2R5C blood marker that may detect Alzheimer’s disease earlier
Researchers report that declining PPP2R5C levels in blood may signal early Alzheimer’s pathology, offering new insight into tau…
Brain neurons after exercise drive long-term endurance gains
When you finish a run, your muscles may feel like they did all the work. But researchers at…
Exercise-induced activation of neurons mediates improvements in endurance
Exercise does more than strengthen muscles; it also rewires the brain. In a study publishing February 12 in the Cell Press journal Neuron,…
Neuron lattice structure may guard against neurodegeneration
Brain cells are constantly swallowing material from the fluid that surrounds them – signaling molecules, nutrients, even pieces of their own surfaces – in a process…
Estrogen levels in the brain may play a role in women’s risk of stress-related memory problems
Experiencing multiple acute stresses at the same time, as in natural disasters or mass shootings, can leave lasting…
Aging brains struggle to recycle synaptic proteins
As we age, we begin to lose the connections that wire up our brains-and neuroscientists aren’t sure why. …
Hippocampus reorganizes memories to anticipate future outcomes, study finds
A preclinical study published in Nature has found evidence that the hippocampus, the brain region that stores memory, also reorganizes…
Overactive protein cleanup disrupts nuclear pores in neurodegenerative disease
When it comes to neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and certain forms of dementia, researchers…
