Scientific study of malnutrition increased in the 1920s and 1930s, and grew even more common after World War II. Non-governmental organizations and United Nations agencies began to devote considerable energy to alleviating malnutrition around the world. The exact methods and priorities for doing this tended to fluctuate over the years, with varying levels of focus on different types of malnutrition like Kwashiorkor or Marasmus; varying levels of concern on protein deficiency compared to vitamins, minerals and lack of raw calories; and varying priorities given to the problem of malnutrition in general compared to other health and development concerns. The green Revolution of the 1950s and 1960s saw considerable improvement in capability to prevent malnutrition.One of the first official global documents addressing Food security and global malnutrition was the 1948 Universal Declaration of Human Rights(UDHR). Within this document it stated that access to food was part of an adequate right to a standard of living. The Right to food was asserted in the International Covenant on Economic, Social and Cultural Rights, a treaty adopted by the United Nations General Assembly on December 16, 1966. The Right to food is a human right for people to feed themselves in dignity, be free from hunger, food insecurity, and malnutrition. As of 2018, the treaty has been signed by 166 countries, by signing states agreed to take steps to the maximum of their available resources to achieve the right to adequate food.
Inactivating V1 with TMS could induce some degree of akinetopsia 60–70 ms after the onset of the visual stimulus. TMS of V1 is not nearly as effective in inducing akinetopsia as TMS of V5. Alzheimers disease
Besides memory problems, Alzheimers patients may have varying degrees of akinetopsia. This could contribute to their marked disorientation. While Pelak and Hoyt have recorded an Alzheimers case study, there has not been much research done on the subject yet. Antidepressants
Inconspicuous akinetopsia can be triggered by high doses of certain antidepressants with vision returning to normal once the dosage is reduced. Areas of visual perception
Two relevant visual areas for motion processing are V5 and V1. These areas are separated by their function in vision. A functional area is a set of neurons with common selectivity and stimulation of this area, specifically behavioral influences. There have been over 30 specialized processing areas found in the visual cortex. V5
V5, also known as visual area MT (middle temporal), is located laterally and ventrally in the temporal lobe, near the intersection of the ascending limb of the inferior temporal sulcus and the lateral occipital sulcus. All of the neurons in V5 are motion selective, and most are directionally selective. Evidence of functional specialization of V5 was first found in primates. Patients with akinetopsia tend to have unilateral or bi-lateral damage to the V5. V1
V1, also known as the primary visual cortex, is located in Brodmann area 17.
