An analysis of the relationship of "the Mozart effect" with BDNF levels in anatomy education
(2024.01.01) Petekkaya, E.; Aykar, D.Ü.; Kaptan, Z.
In 1993, an increase was observed in the spatial IQ scores of the volunteers who listened to Mozart's sonata K448 for 10 min, and this phenomenon entered the literature as the "Mozart effect." Other studies have shown that this effect is particularly evident in spatial skill tests. A large body of research has provided evidence that spatial ability is associated with success in learning anatomy. In this study, Kastamonu University Faculty of Medicine students were divided into two groups during 16-h practical training spanning 30 days. While one of the groups listened to Mozart's K448 sonata as the background music in all lessons, the control group attended the lessons in their standard form. At the end of each lesson, all students solved a modified mental rotation test including questions involving anatomical structures. Before starting the study, after the first laboratory class, on the 15th and 30th day of the study, blood samples were taken from the participants, and plasma brain-derived neurotrophic factor (BDNF) levels were determined. The effect of time on mental rotation score and plasma BDNF level was significant (p < 0.001 for both). The effect of group was also significant (p < 0.001 for both). Pairwise comparisons showed significance in the fifth, sixth, seventh, and eighth mental rotation test (p < 0.001, p = 0.041, p < 0.001, p < 0.001, respectively) and in the third (Day 15) and fourth (Day 30) BDNF measurement (p < 0.001 for both). Our findings may indicate that specific background music may be useful for anatomy teaching.

Correlation of metal ions with specific brain region volumes in neurodegenerative diseases
(2023) Melek, İ.M.; Kus, B.; Kaptan, Z.; Petekkaya, E.
Background/aim: There are reports stating that deteriorations in metal homeostasis in neurodegenerative diseases promote abnormal protein accumulation. In this study, the serum metal levels in Alzheimer’s disease (AD) and Parkinson’s disease (PD) and its relationship with the cortical regions of the brain were investigated. Materials and methods: The patients were divided into 3 groups consisting of the AD group, PD group, and healthy control group (n = 15 for each). The volumes of specific brain regions were measured over the participants’ 3-dimensional magnetic resonance images, and they were compared across the groups. Copper, zinc, iron, and ferritin levels in the serums were determined, and their correlations with the brain region volumes were examined. Results: The volumes of left hippocampus and right substantia nigra were lower in the AD and PD groups, while the volume of the left nucleus caudatus (CdN) and bilateral insula were lower in the AD group compared to the control group. Serum zinc levels were lower in the AD and PD groups, while the iron level was lower in the PD group in comparison to the control group. In addition, the serum ferritin level was higher in the AD group than in the control group. Serum zinc and copper levels in the AD group were positively corre- lated with the volumes of the right entorhinal cortex, thalamus, CdN, and insula. Serum zinc and copper levels in the PD group showed a negative correlation with the left nucleus accumbens (NAc), right putamen, and right insula volumes. While the serum ferritin level in the PD group displayed a positive correlation with the bilateral CdN, putamen, and NAc, as well as the right hippocampus and insula volumes, no area was detected that showed a correlation with the serum ferritin level in the AD group. Conclusion: A relationship was determined between the serum metal levels in the AD and PD groups and certain brain cortical regions that showed volumetric changes, which can be important for the early diagnosis of neurodegenerative diseases.
