Microbes and mental health; combatting brain cancer spread; delayed remembering, and more.
Everyone has had a “gut feeling”—some liken it to “butterflies” in the stomach before a stressful event, while others deem it a type of intuition—and scientists are bringing this age-old phenomenon into the present-day lab in order to better understand how mental health disorders arise and how they might be treated better.
Scientists at the University of Toledo Health Science Campus and Van Andel Research Institute have discovered an innovative way that may stop the spread of the most lethal and aggressive brain cancer glioblastoma multiforme. In laboratory studies, scientists demonstrated that activating a specific family of proteins halted cancer cell migration into healthy tissue.
For adults, memories tend to fade with time. But a new study has shown that there are circumstances under which the opposite is true for small children: they can remember a piece of information better days later than they can on the day they first learned it.
Using eye-tracking glasses, Queen’s University professor Adam Szulewski has developed a new method to determine how novice medical students learn compared to more experienced medical professionals.
A new study links anxiety, the orbitofrontal cortex (OFC), and optimism, finding that healthy adults who have larger OFCs tend to be more optimistic and less anxious. The new analysis, reported in the journal Social, Cognitive and Affective Neuroscience, offers the first evidence that optimism plays a mediating role in the relationship between the size of the OFC and anxiety.
A recent retrospective study evaluating continuous electroencephalography (cEEG) of children in intensive care units (ICUs) found a higher than anticipated number of seizures. The work also identified several conditions closely associated with the seizures, and suggests that cEEG monitoring may be a valuable tool for helping to identify and treat neurological problems in patients who are 14 months old or younger.
Pain is a negative feeling that we want to get rid of as soon as possible. In order to protect our bodies, we react for example by withdrawing the hand. This action is usually understood as the consequence of the perception of pain. A team from the Technical University of Munich (TUM) has now shown that perception, the impulse to act and provision of energy to do so take place in the brain simultaneously and not, as was expected, one after the other.
