Even for people with a gene mutation tied to Parkinson’s disease, coffee consumption may be associated with a lower risk of actually developing the disease,…
Mice treated with apigenin had better memory and developmental milestone scores. The plant compound apigenin improved the cognitive and memory deficits usually seen in a…
Caltech researchers have discovered that hard-wired neural circuits governing aggression in mice are strengthened following their victories in aggressive encounters. Credit: Caltech Like a champion…
Air pollution was significantly associated with an increased risk of hospital admissions for several neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and other dementias, in…
Our brains can’t always reliably evaluate experiences that unfold over time We tend to give disproportionate weight to the later part of an experience This…
A new approach called integrated neurophotonics could allow researchers to track the activity of all the neurons that make up a particular brain circuit. Credit:…
A female mosquito has finely tuned senses that help her find the blood meal she needs in order to reproduce. New research reveals how the…
Dopamine, serotonin involved in sub-second perception, cognition. In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals —…
A new MIT study reveals that encoding memories in engram cells is controlled by large-scale remodeling of the proteins and DNA that make up cells’…
Researchers at the department of Ethology at Eötvös Loránd University trained the dogs so they are capable of scanning the brains of awake, unrestrained dogs.…
Similar to the cortex of mammals, the nerve cells in certain areas of the brain of birds are organized in vertical layers and horizontal columns.…
“Area 32” balances activity from cognitive and emotional brain areas in primates. Navigating through life requires balancing emotion and reason, a feat accomplished by the…
Is the world prepared a wave of neurological consequences that may be on its way as a result of COVID-19? This question is at the…
Could over-the-counter “smart drugs” pose health risks? Supplements that claim to improve mental focus and memory may contain unapproved pharmaceutical drugs and in potentially dangerous…
Contrary to previous theories, fear and anxiety reflect shared neural building blocks. Fear and anxiety reflect overlapping brain circuits, according to research published today (September…
Brain cells called astrocytes appear in green, and purple represents the leakage of the blood-brain barrier. Together they show that leakage occurs around areas where…
Doryteuthis pealeii, often called the Woods Hole squid. Studies with D. pealeii have led to major advances in neurobiology, including description of the fundamental mechanisms…
A UCLA-led team of scientists reports on why sleep is vital to our health and how the brain heals during sleep. In very early life,…
