Artificial intelligence (AI) draws inspiration from current knowledge of the human brain, artificially replicating some of its learning processes and functions. The extent to which artificial agents successfully emulate the ...
The melanin-concentrating hormone (MCH) is a neuropeptide (i.e., a compound that transmits information in the brain) produced by neurons in a region known as the lateral hypothalamic area (LHA). Past studies have found that ...
Over the past decades, psychologists and neuroscientists worldwide have been trying to gain a better understanding of how humans make simple decisions about the state of the world around them. To do this, they devised theoretical ...
(Phys.org)—Studying patterns of neuronal activity is difficult, and in the absence of in vivo data, scientists have relied on theoretical models to establish likely processes in the brain. In 1982, scientist John Hopfield ...
Inside the brains of people with psychosis, two key systems are malfunctioning: a "filter" that directs attention toward important external events and internal thoughts, and a "predictor" composed of pathways that anticipate ...
