Memories change the way nerves exchange signals at points of contact called synapses. In this image, magnified thousands of times, a nerve fiber, shown in purple, meets a yellow cell body. 8 ...
Dec 9, 2020 · Study sheds light on how neurons form long-term memories. On a late summer day in 1953, a young man who would soon be known as patient H.M. underwent experimental surgery. In an attempt to treat his debilitating seizures, a surgeon removed portions of his brain, including part of a structure called the hippocampus. The seizures stopped.
Mar 7, 2022 · This finding improves our understanding of how the human brain forms memories and could have implications in memory disorders such as Alzheimer’s disease. The study was supported by the National Institutes of Health’s Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative and published in Nature Neuroscience.
Nov 21, 2023 · The challenge for scientists is to identify the "difference that makes a difference" for forming a memory -- the change in a brain that stores a memory is refereed to as an 'engram', which retains ...
Jan 4, 2024 · The aim of the mouse experiment led by Cogno was to find out how the brain organises experiences in specific sequences, so that we can navigate and remember things in a functioning way.

Jan 21, 2022 · Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons. Since then, neuroscientists have attempted to understand the physical changes associated with memory formation. But visualizing and mapping synapses is challenging ...
