Newer Generations with Larger Brains are Influencing Dementia

Biology, Evolution, Neuroscience, Science / Jorge Paka

Larger brain size indicates enhanced brain health and cognitive abilities. Since the 1930s, there has been a consistent increase in brain size. A recent study highlights the implications of this growth on the likelihood of developing dementia, specifically Alzheimer’s disease. By 2020, more than 55 million people worldwide had dementia, with projections indicating a doubling

Humans Have a Vital Sixth Sense for Health

1 Comment / Biology, Neuroscience, Science / Jorge Paka

While most people are familiar with the traditional five senses (touch, sight, hearing, smell, and taste), not everyone is aware of our additional sense known as interoception. Interoception pertains to our perception of the body’s internal state. It enables us to sense and comprehend internal signals regulating crucial bodily functions such as hunger, thirst, body

Study Indicates Poverty Speeds Up Brain Aging

4 Comments / Neuroscience, Science / Jorge Paka

Researchers have identified a correlation between lower household income and accelerated degradation of the white matter in the brain. While the levels of this white matter naturally decrease as individuals age, residing in poverty appears to hasten this decline. The study, conducted by researchers from the University of Lausanne and the University of Geneva in

Anger Can be Managed But Venting Alone Isn’t Effective

Healthcare, Medicine, Neuroscience / Jorge Paka

Researchers have discovered that participating in activities intended to release anger, such as jogging or using a punching bag, is unlikely to effectively reduce anger. Instead, they recommend engaging in activities that lower physical arousal. Anger, an undesirable emotion for many, appears to be increasingly prevalent nowadays due to various factors. A Gallup poll revealed

Microplastics Found in Human Organs, Even Brain, Study Says

Healthcare, Medicine, Neuroscience, Science / Eduardo Paulo

According to a fresh investigation, microplastics could be as prevalent inside the body as they are in the environment.In the study, scientists exposed mice to varying amounts of microplastics through drinking water and observed how these particles affected their organs and behavior. Microplastics are tiny plastic pieces, less than 5 mm long, originating from larger

Scientists Discovered and Deactivated a Brain Fear Switch

Medicine, Neuroscience, Science / Jorge Paka

The sensation of hairs standing on end, the cold sensation in the stomach, the rapid heartbeat triggered by a sudden movement in the shadows—these experiences evoke fear. Fear, while capable of causing distress and discomfort, can also be oddly exhilarating. However, it serves a crucial purpose as an instinctual reaction to danger, potentially enhancing our
