A new study, performed by an international team of researchers from the University of California, Irvine, USA, and the University of Tsukuba, Japan, suggests that only 10 minutes of light physical activity may boost your memory.
To check their hypothesis, the researchers asked 36 healthy adult participants to carry out only 10 minutes of light exercise. After that, the scientists used high-resolution functional MRI to measure changes in brain activity.
Michael Yassa, a project co-leader, says: “What we observed is that these 10-minute periods of exercise showed results immediately afterward.” Yassa and his team are planning to continue investigating. Next, they are going to run longer-term studies in older adults who have the higher risk of cognitive decline.
Our brain combines smell with the information about space and time to form episodic vivid memories, according to a recent research, published in the journal Nature Communications. These findings can help improve sniff tests for the Alzheimer’s disease.
In the course of the study, a team of researchers examined the role of the anterior olfactory nucleus (AON) in memory using a mouse model in a range of experiments. They discovered a previously unknown neural pathway between the hippocampus and the AON.
Study co-author Afif Aqrabawi says: “[The findings demonstrate] that we now understand which circuits in the brain govern the episodic memory for the smell. The circuit can now be used as a model to study fundamental aspects of human episodic memory and the other odor memory deficits seen in neurogenerative conditions.”
According to the findings of a new study from Queen’s University Belfast, narcissistic teens may show better results at school.
For the study, a lead researcher Kostas Papageorgiou and his colleagues recruited 340 teenage students from different high schools in Milan, Italy. Having assessed the received data, the scientists concluded that teens with higher levels of subclinical narcissism tend to be more mentally tough what leads to better performance at school.
Lead researchers Kostas Papageorgiou, a lecturer in developmental psychopathology at Queen’s University Belfast in the United Kingdom, says: “People who score high on subclinical narcissism may be at an advantage because their heightened sense of self-worth may mean they are motivated, assertive, and successful in certain contexts.”
A new study from the United Kingdom suggests that a simple quiet rest, just for 10 minutes, may help to memorize new information in fine detail.
To study this effect, the researchers designed a memory test to assess the ability to keep finely graded information. For the experiment, the researchers took the information on memorizing from 60 young male and female participants whose average age was 21 years.
Michael Craig, a researcher from the Heriot-Watt University in Edinburgh, United Kingdom, says: “This new finding provides the first evidence that a brief period of quiet rest can help us to retain more detailed memories.”
A team of scientists from the University of Cambridge has identified a chemical within the region of the brain responsible for memory that allows us to suppress undesired thoughts. This helps explain why people with anxiety, post-traumatic stress disorder (PTSD), depression, and schizophrenia often have persistent intrusive thoughts when these circuits go wrong.
In their study, the researchers used a task known as the ‘Think/No-Think’ procedure to identify a significant new brain process enabling the prefrontal cortex to successfully inhibit our thoughts.
Using functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy, the scientists managed to observe what was happening within the key regions of the brain as the participants tried to inhibit their thoughts. The researchers were able to measure brain chemistry with the help of spectroscopy.
