According to a recent European study, persistent bullying can cause the reshape of the developing brain of teenagers.
For the study, a team of researchers took data from the long-term study on teenage brain development and mental health collected from 682 teens aged from 14 to 19 from England, Ireland, France, and Germany.
Lead study author Erin Burke Quinlan from King’s College London comments: “Although not classically considered relevant to anxiety, the importance of structural changes in the putamen and caudate to the development of anxiety most likely lies in their contribution to related behaviors such as reward sensitivity, motivation, conditioning, attention, and emotional processing.”
New research from Arizona State University in Tempe, US, suggests that uterus may interact with the brain and influence the memory.
For the study, a team of researchers used a rat model. The female rats were included into four groups, and the rats from three groups underwent surgeries that were equivalent to the surgical removal of the ovaries and removal of the uterus in humans.
After six weeks of experiments and observation, the researchers found that for the female rats with the removed uterus it was more complicated to navigate through the maze than for the female rats from other groups.
First study author Stephanie Koebele, a psychology graduate student at Arizona State University, comments: “The surgical removal of just the uterus had a unique and negative effect on working memory, or how much information the rats were able to manage simultaneously, an effect we saw after the rats learned the rules of the maze.”
According to the findings of a recent research, published in the JNeurosci, regular talking to young children associated with the stronger connections between two developing brain regions critical for language.
The research was held independently of parental income and education. This means that engaging children in a conversation from an early age may promote their language skills regardless of socioeconomic status.
For the study, the team of researchers analyzed data received from 40 of children aged from 4 to 6 years. The scientists discovered that greater conversational turn-taking was associated with the stronger connections between brain regions that are critical for the comprehension and production of speech (Wernicke’s area and Broca’s area).
A new study from the Stevens School of Business in New Jersey, USA, finds that even coffee scent can sharpen the brain under certain conditions.
In the study, 114 students were involved. The participants were divided into two group and both had to answer mathematical questions. One group has been exposed to a coffee smell during the study. The scent was free from caffeine and other stimulants.
The researchers also executed a follow-up survey. They asked questions of 208 individuals not involved in the first test and found that a coffee scent was associated with being more alert and energetic, compared with other scents such as flowers, or with no scent.
Lead researchers of the study Adriana Madzhrov says: “Olfaction is one of our most powerful senses. Employers, architects, building developers, retail space managers and others, can use subtle scents to help shape employees’ or occupants’ experience with their environment.”
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.”
