Morphological characterization of the melanin-concentrating hormone in the brain of humans, rodents, and birds
The regulation of food intake and energy balance is an extremely complex process involving numerous physiological and neurobiological mechanisms. The central nervous system, particularly the hypothalamus, plays a key role in integrating these mechanisms. Signals from various areas of the brain, which originate from peripheral systems such as the digestive system and adipose tissue, arrive in the form of humoral and neural impulses. In response to these factors, the hypothalamus decides whether an increase or decrease in food intake is necessary. Factors Influencing Food Intake One of the factors influencing food intake is our mood, which is also affected by the limbic system and other higher brain structures. This complex…

The aging of humans is similar to that of monkeys
The study of aging processes among living beings is an incredibly exciting field that raises numerous questions from the perspective of biology and evolution. The aging of animals is not solely explained by biochemical changes associated with advancing age but is also closely related to interspecies differences. Understanding the similarities and differences between humans and monkeys may be key to a more comprehensive understanding of aging processes. New research indicates that aging results not only from environmental factors but also from the combined effects of genetic background and lifestyle differences. Researchers studying the aging processes of various monkey species have concluded that the process of human aging is much more…
