Effects of Bioceramic Material and Colored Light Irradiation on Learning and Memory in Aging Rats

ABSTRACT

Aging is characterized by molecular damage from free radicals, leading to neural dysfunction and memory impairment. This study investigated using bioceramic material and colored light to mitigate neurodegenerative symptoms in aging rats. We assessed the effects of different color light spectrums on D-galactose-induced aging rats using the Morris water maze, novel object recognition, and open field tests. Findings revealed that bioceramic material with various light wavelengths improved activity, recognition, and memory in aging rats. Significant enhancements were observed in the open field and novel object recognition tests, with a trend toward improvement in the Morris water maze. These effects are attributed to the antioxidant properties and microcirculation enhancement associated with bioceramic materials. Color stimulation may impact enzymes, human physiology, psychological activity, and the autonomic nervous system. This study highlights the significance of exploring novel interventions for neurodegenerative symptoms and memory deficits in aging rats. Results indicate that bioceramic material with different colored light spectrums positively influences cognitive function. These findings contribute to our understanding of the therapeutic potential of bioceramic materials and emphasize the need for further research in this area.
