PURPOSE Previous studies have shown that physical activity improves learning and memory. Present study was performed to determine the effects of short term and long term treadmill exercise on learning, memory consolidation and retrieval of passive avoidance learning in an animal model. METHODS In this study fifty male Wistar rats with 3-4 months of age were randomly divided into five groups (...
Acquisition of an active bar-pressing avoidance response was investigated in a factorial design with 3, 5 or 9 s CS-US intervals and CSs of 70- or 50-dB of white noise. As the CS-US interval increased the required time to meet the avoidance criterion decreased. The shorter the CS-US interval and the more intense the CS, the shorter the median response latencies observed at the end of the traini...
Background & Aims: Preventive effects of exercise on human health is well documented but there are some challenges about the preventive effects of exercise on the incidence, intensity, or the prevalence of clinical and paraclinical outcomes of neurodegenerative disease. The study of different aspects of exercise in finding the mechanism of prevention is very important. The preventive effects of...
Objectives In recent decades, it has become important to approach aging issues from the point of view that can ensure older adults’ Quality of Life (QoL). As a result, countries have adopted a positive perspective with regard to aging, including active aging. The fact is that indigenous understanding of active aging is an unavoidable necessity for every society. Thus, the current study&rs...
Interest in instrumental learning in earthworms dates back to 1912 when Yerkes concluded that they can learn a spatial discrimination in a T-maze. Rosenkoetter and Boice determined in the 1970s that the "learning" that Yerkes observed was probably chemotaxis and not learning at all. We examined a different form of instrumental learning: the ability to learn both to escape and to avoid an aversi...
Introduction: Lead (Pb) is a neurotoxin that its different effects on the central nervous system are well-known. Previous studies have reported the potent effects of vitamin C on memory.The present study was undertaken to evaluate the protective effects of vitamin C against leadinduced amnesia. Methods: Male Wistar rats were divided into 4 groups: the control (saline), negative contr...
