Effects of postnatal protein malnutrition on learning and memory procedures

Nutritional Neuroscience, 2010
Protein malnutrition induces structural, neurochemical and functional changes in the central nervous system leading to alterations in cognitive and behavioral development of rats. The aim of this work was to investigate the effects of postnatal protein malnutrition on learning and memory tasks.

I. Malnutrition and learning: Malnutrition, hunger, and behavior

Journal of the American Dietetic Association, 1973
Severe malnutrition affects development of the brain and central nervous system. The effects of moderate malnutrition are less obvious and not fully understood. Knowledge in both areas is reviewed here.

Malnutrition and Behavior: the Performance Versus Learning Problem Revisited

The Journal of Nutrition, 1980
At 100 days of age rats, whose dams suffered severe zinc deficiency and/or undernutrition throughout lactation, were tested in two learning tasks. One test was an original discrimination learning task and the other test was a more difficult reverse discrimination learning task.

Malnutrition, learning, and behavior

Ecology of Food and Nutrition, 1973
This paper critically reviews the reported relationships between malnutrition and learning. Since malnutrition is not randomly distributed in the social system, the relationships between malnutrition and intellectual development are often confounded by the relationship between social class and malnutrition.

Malnutrition and social isolation: Learning in the developing rhesus monkey

Physiology & Behavior, 1978
Abstract Early diet and environment were manipulated in a factorial experiment in which the mastery of a spatial delayed alternation task was investigated. Protein-calorie malnutrition resulted in a retarded rate of acquisition while partial social isolation appeared to enhance performance relative to socially reared groups.

Malnutrition, Learning and Animal Models of Cognition

1979
The possibility that severe malnutrition experienced eariy in the life of a child may permanently lower ultimate cognitive potential has stimulated a great deal of multidisciplinary research. The major objectives were to determine (1) whether malnutrition does alter the cognitive functioning of the brain, (2) whether the effects are permanent, and (3 ...

Malnutrition—a neglected cause of learning failure

Postgraduate Medicine, 1986
PreviewAlthough often thought of as unique to developing nations, malnutrition in early life actually exists in certain population subgroups in the United States. Evidence now shows that the long-term effects of mainutrition go far beyond physical growth and development.

Protein Malnutrition and Complex Learning in the Chicken

1975
Protein malnutrition during periods of rapid growth has long been hypothesized to have deleterious effects on mental capacity (cf. Birch and Gussow, 1970; Scrimshaw and Gordon, 1968). Such a hypothesis is difficult to evaluate since performance is the product of many factors other than intellectual capacity, such as motivation, individual experiential ...

Food Insecurity and Malnutrition in Rural Tanzania: Mapping Perceptions for Social Learning

Ecology of Food and Nutrition, 2021
In Tanzania, a high level of hunger persists. Several factors compound a complex scenario of food insecurity. Contextual aspects at the community level can influence the maintenance of the vulnerable local conditions. This article aims to better understand these aspects by investigating community problem perceptions in n = 04 remote rural villages in ...

Malnutrition, brain development, learning, and behavior

Nutrition Research, 1998
Three widely prevalent nutritional deficiencies are recognized to have the potential for permanent adverse effects on learning and behavior: protein-energy, iron, and iodine. Supplementation with adequate protein and calories during the first two years of life improves the cognitive performance of poorly nourished children, and the benefits may be even
