Prenatal flavour learning, Influencing food preference

Prenatal flavour learning: Influencing food preference

An unborn baby begins ingesting amniotic fluid at around 12 weeks and a powerful sense of smell starts developing by 28 weeks. Based on this prenatal development process, it is worth determining whether or not babies can learn about flavours and odours even before they are born. Several studies have explored this possibility. Researchers J. […]

Behavioural effects of chronic stress, Sociability and confidence

Behavioural effects of chronic stress: Sociability and confidence

Because stress can affect the mental health of individuals, it can also bring forth several behavioural problems. According to several studies, the common behavioural effects of chronic stress include diminished sociability and reduced confidence. Thus, people subjected under too much stress for a prolonged period often exhibit antisocial and risk aversion tendencies. Researchers Carmen Sandi […]

Stressful environment for children. Environmental factors that trigger high cortisol levels in children

Stressful environment for children

Exposure to stressful environment triggers high cortisol levels in children. Remember that stress is a normal biological response and that the body naturally produces and releases cortisol as part of normal biological functions. But certain external or environmental factors can cause chronic stress and disrupt normal cortisol production. Several studies have revealed that children living in a […]

Groundbreaking study establishes link between the brain and immune system

Study establishes link between the brain and immune system

For several decades, scientific and popular understanding had characterised the central nervous system as lacking of a classical lymphatic drainage system despite an established consensus that the central nervous system undergoes constant immune surveillance that takes place within the meningeal compartment. The mechanisms involving the movement of immune cells in and out of the central […]
