Memory decline is considered a normal part of the aging process, while the relationship between melatonin deficit and cognitive functions is complex and not fully understood. The present study explored the role of melatonin deficiency induced in different age stages on changes in recognition and spatial memory in rats. Age-related worsening of memory learning capacity, working and short-term memory, tested in the Y maze, object recognition test, and radial arm maze was detected. Pinealectomy negatively impacted memory capacity in the young adult and middle-aged rats, while old rats were unaffe

Understanding and potentially reversing memory decline necessitates a comprehensive examination of memory's evolution throughout life. Traditional memory assessments, however, suffer from a lack of comparability across different age groups due to the diverse nature of the tests employed. Addressing this gap, our study introduces a novel, ACT-R model-based memory assessment designed to provide a consistent metric for evaluating memory function across a lifespan, from 5 to 85-year-olds. This approach allows for direct comparison across various tasks and materials tailored to specific age groups.
