Surveys and statistics suggest that mental illnesses are becoming increasingly widespread, as the number of people worldwide accessing mental health services has increased in recent years. Understanding the factors that can predict well-being and contribute to the...
Past psychology studies have found that on average, older adults tend to view the world in a more positive light than younger adults. People in their 30s to 50s, in fact, often display a negativity bias, which essentially means that they are more prone to remember...
Sleep is known to play a key role in facilitating various physiological processes, while also contributing to the healthy functioning of the brain. Lack of sleep and poor sleep quality have been linked to various chronic health and mental health issues, including high...
Fasting, the voluntary abstention from eating and sometimes drinking for a set time, has become increasingly widespread, as some studies have found that it could boost the immune system and help prevent the development of some diseases. There are now several...
In their daily lives, humans can encounter many situations that can put them at a varying degree of risk, or in other words, situations in which their choices can increase or decrease the possibility that an adverse event will occur. In these situations, different...
Humans commonly evaluate the beauty of other humans, as well as objects, places, natural landscapes, and even animals. The innate human tendency to make aesthetic judgments has been the topic of numerous psychological studies, yet its neural and cognitive...
In mammals, the perception of visual stimuli is supported by the coordinated activity of thousands of neurons in different brain regions. The images perceived by the eyes are represented in the brain, passing various steps through which representations are...
Mice are among the animal species most employed in neuroscience studies, as they are mammals (i.e., their brain is in some ways similar to the human brain) and their genetics or behaviors can be easily manipulated in experimental settings. While training mice to...
The activity of neurons in the mammalian brain has been found to be linked with various physiological processes, including the flow of blood that provides them with the energy required to function (i.e., cerebral blood flow). This close relationship between brain...
Human decision-making has been the focus of a wide range of research studies. Collectively, these research efforts could help to understand better how people make different types of everyday choices while also shedding light on the neural processes underpinning these...
