Geoffrey Hinton, a pioneer in artificial intelligence, believes that studying artificial neural networks can reveal secrets about how human brains learn. While backpropagation, a key algorithm in AI, was once considered too complex for biological brains, recent research suggests it might play a role in human learning. This discovery could revolutionize our understanding of the brain and lead to breakthroughs in AI.
Scientists have discovered that slow-acting molecules called neuropeptides, not fast-acting neurotransmitters, are the primary messengers controlling the brain’s fear circuit. This finding challenges conventional understanding and could lead to new treatments for anxiety and PTSD.
Our perception of color can be influenced by various factors like lighting, memory, and even the fatigue of our photoreceptor cells. This article delves into the science behind these fascinating color illusions, explaining why a dress might appear white and gold to some and blue and black to others, or how staring at a red object can create a green afterimage.
Researchers have created a detailed 3D map of a tiny slice of the human brain, revealing intricate networks of neurons and other structures at an unprecedented scale. The map, which was constructed using advanced microscopy techniques and machine learning, provides new insights into the brain’s inner workings and could help researchers understand neurological disorders.
Scientists have created a comprehensive map of the brain cells responsible for keeping us awake. This map could help improve treatments for people in comas and vegetative states, and provide a better understanding of human consciousness.
Dr. Miguel Toribio-Mateas, a renowned neuroscientist, has suggested the consumption of kefir, a fermented milk beverage, as a potential aid in reducing ADHD symptoms in children. Research conducted by Dr. Mateas and his team, published in the BMJ Open journal, examined the impact of kefir on ADHD symptomatology, sleep quality, attention, and gut microbiome composition in children diagnosed with ADHD. The study, which lasted for six weeks, revealed improvements in impulsivity, hyperactivity, and sleep in the participants who consumed kefir daily.
