A new study reveals axon density is lower than previously believed between distant regions of the brain.
In a study published in the journal Cell Reports, an international team of investigators used biomarkers, statistical modeling, and other techniques to develop tools for measuring the biological ages of various organ systems. Based on their findings, the researchers report that there are multiple “clocks” within the body that vary widely based on factors including genetics and lifestyle in each individual.
Researchers have identified a new pathway in the brain that plays an important role in our response to fear.
Researchers have now demonstrated that the brain waves during periods of deep sleep in a specific area of the brain can be used to determine the extent of an individual’s propensity for risk during their everyday life.
A study at Boston Children’s Hospital explains for the first time why COVID-19 causes severe inflammation in some people, leading to acute respiratory distress and multi-organ damage.
A team of researchers has found a link between the use of antibiotics by middle-aged women and cognitive decline later in life. The group has published a paper describing their work on the open-access site PLOS ONE.
Women who experienced childhood trauma had an increased risk of developing multiple sclerosis later in life. The evidence suggests childhood abuse and trauma can alter the immune system and increase the risk of developing autoimmune diseases.
A study has found no increased risk of developing brain tumors regardless of whether a person was a frequent cell phone user or if they had never used a cell phone before.
The consolidation of learning that occurs during sleep is a result of the learning process and not merely because certain brain regions get used a lot during learning. This finding is published in The Journal of Neuroscience and resolves a long-standing debate among sleep researchers.
People who grew up in rural or suburban areas have better spatial navigation skills than those raised in cities, particularly cities with grid-pattern streets, finds a new study.
The return of consciousness after traumatic brain injury (TBI) remains something of a mystery for scientists and is not easy to predict. A series of recently published studies have found that by using technologies to monitor brain functions after TBI, scientists may be able to better predict who will “wake up” after TBI and what brain circuits to target to potentially treat disorders of consciousness.
Finally this week, researchers have established for the first time a link between depressive disorders and mechanical changes in blood cells.
