Imposter Syndrome Is Not Related To Age Or Gender

Have you ever felt that any success you are having is random, and is only because of some external circumstances or just luck? You may have what is called imposter syndrome and you are not alone. People who systematically underestimate themselves and their own performance live in constant fear that their “deception” will be exposed.…

Having Bad Dreams Could Be Early Parkinson’s Disease Sign

In a group of older men, individuals having frequent bad dreams were twice as likely to be later diagnosed with Parkinson’s disease as those who did not, new research from University of Birmingham reports. Although it can be really beneficial to diagnose Parkinson’s disease early, there are very few risk indicators and many of these…

Adult Neuron Growth From Optogenetic Stimulation

Researchers at University of North Carolina School of Medicine have zeroed in on a specific kind of neuron in mice to increase the production of neural stem cells and spur on the creation of new adult neurons. Targeting these cells modulated memory retrieval and altered anxiety-like behaviors in mice, their study1 details. Targeting the hypothalamic…

Anti-inflammatory Drugs Linked With Increased Risk Of Chronic Pain

Use of steroids and anti-inflammatory drugs for pain relief could raise the chances of developing chronic pain, new research from McGill University and colleagues in Italy suggests. The findings bring questions for conventional practices used to treat pain, of which chronic low back pain is the most commonly reported chronic pain condition. For many decades…

A Bigger Striatum Is More Likely Among Psychopaths

The striatum, a region of the forebrain, was on average 10% larger in psychopathic individuals compared to a control group of individuals that had low or no psychopathic traits, in a new study1. Previous studies have pointed to an overly active striatum in psychopaths but have not conclusively determined the impact of its size on…

Stress Resilience Correlates With Regional Myelin Changes In The Brain

Acute stress is associated with increased myelination of axons in areas of the brain associated with memory and emotions, recent research shows. The study1, from scientists at the University of California, Berkeley, and UC San Francisco (UCSF), represents a potential explanation for why some people are quick to recover from, and others vulnerable to traumatic…

Astrocyte Electrical Activity Changes How Neurons Function

A previously unknown function of astrocytes brings a new approach for neuroscience researchers that could ultimately lead to treatments for disorders like epilepsy, Alzheimer’s, and traumatic brain injury, scientists report. Astrocytes are glial cells in the brain that communicate with neuronal synapses, cleaning up glutamate and potassium from the extracellular space after neuron activity. The…

Epileptic Seizures Reinforced By Activity-dependent Myelination

Epilepsy seizures increase insulation of nerve fibers involved in seizing, leading the brain to have seizures more efficiently, a new study1 from the Stanford University School of Medicine has found. I was surprised by what we saw. Initially, I thought that because this is a disease process, we would see deficient myelination somehow. What we’re…
