While the visual cortex stores individual images in the brain, the hippocampus plays a significant role in the ability to recognize a sequence of images.
Reduction of semantic memory could be an indicator of Alzheimer's disease 12 years before onset. Researchers examine different types of memory loss associated with dementia.
Combining EEG data and MRI brain scans, researchers discovered how, during sleep, the hippocampus sends memory information it has stored throughout the day to the cerebral cortex, allowing for memory consolidation.
Over 50% of people surveyed reporting they feel uneasy about returning to in-person interactions, regardless of vaccination status, following covid lockdowns. Researchers share their thoughts on how social isolation and resocialization could impact the brain.
Gut microbes that metabolize tryptophan secrete indoles that stimulate the development of new neurons in the adult brain.
Immersive virtual reality enhances theta and eta waves in the hippocampus, improving memory, learning and neuroplasticity.
Specific hippocampal neurons may be involved in time-related memory encoding. Findings reveal the human brain contains time-tracking neurons.
Study finds amyloid-beta plaques may not be the cause of memory loss associated with Alzheimer's disease, but instead a consequence of the disease. Regardless of the levels of amyloid plaques, researchers found individuals with high levels of amyloid peptide were cognitively normal. Higher levels of soluble amyloid beta peptide were also linked to people having a larger hippocampus.
