Previous research suggests that brain knowledge, either right or wrong, can influence the way children think about themselves, and how they behave. If this knowledge is negatively framed, this can have a negative effect on their development. Therefore, we investigated whether curiosity, prior knowledge, and science-related curiosity were predictive of correctly distinguishing neuromyths and truths and whether these same predictors were related to the perceived relevance of brain knowledge in their daily lives. Furthermore, we looked at the difference between children in primary school and in secondary school with respect to how much they want to know about the brain, and what they want to know about the brain was examined. To test this, 321 children in primary and secondary schools, aged between 10 and 15 years, filled out a questionnaire about their curiosity and prior knowledge, and they judged whether 25 statements about the brain (13 myths, 11 facts, and 1 opinion) were right or wrong. We found that curiosity, prior knowledge, and science-related curiosity as measured with a questionnaire were not predictive of being better able to distinguish neuromyths and truths. However, in an exploratory analysis we found that a higher number of correctly detected facts predicted a lower number of correctly detected neuromyths. When looking at perceived relevance, higher levels of curiosity and science-related curiosity predicted higher levels of perceived relevance, while prior knowledge did not. No differences between children who go to primary school and secondary school were found in how much they want to know about the brain. Also, the themes they would like to know more about were quite the same, mostly focused on general brain knowledge and brain development. This is the first study that focuses on neuromyths and brain knowledge in children. It is important that more research is done on the effect of believing neuromyths and the influence it has on children’s behavior.Show less

In muscle this protein contributes to membrane integrity. It is also found in the brain, but its function there is unclear. Patients with DMD experience a number of cognitive and behavioral problems, and MRI studies have shown reduced gray matter and total brain volume. The current study aimed to assess whether these MRI findings are progressive and whether neural correlates of psychological problems in DMD are similar to those in healthy controls. Previously-acquired pediatric data was combined with newly-acquired data from adult DMD patients and age- and sex-matched healthy controls. Subjects underwent a magnetic resonance imaging scan and a neuropsychological evaluation. Linear mixed models were used to assess the effect of age and DMD on the ratio of gray matter to cerebrospinal fluid volume (GMV:CSFV) and total brain volume corrected for intracranial volume (TBV:ICV). An independent-samples t-test and a voxel-based morphometry analysis were used to compare gray matter volume in patients with psychological problems to patients without such problems, to identify global or local gray matter reductions in patients with psychological problems. Patients with DMD had reduced GMV:CSFV and TBV:ICV compared to healthy controls (b=-0.43, p<0.001; b=-0.02, p<0.001 respectively). Both GMV:CSFV and TBV:ICV linearly decreased in both groups (b=-0.09, p<0.001; b=-0.003, p<0.001 respectively), but this was not different between-groups (p>0.05). No global (p>0.05) or localized gray matter volume reductions were found in patients with DMD with psychological problems compared to patients without such problems. In both patients and healthy controls gray matter was displaced by cerebrospinal fluid over time, suggesting this process is not a pathological mechanism in DMD. Patients with DMD did have a lower GMV:CSFV and TBV:ICV ratio, suggesting this is a diseased mechanism. No global or local GM reductions were found in patients with DMD with psychological problems compared to patients without such problems.Show less
