While commonly implicated in long-term memory, researchers report the hippocampus plays a critical role in short-term memory and decision making.
Depleting the protein ADORA2B from the blood of mice led to faster cognitive decline, decreased auditory processing, and increased brain inflammation.
Earworms, those songs that get stuck in your head, may help strengthen memories of music and life events, a new study reports.
Following a potentially life-threatening event, people often report seeing their "lives flashing before their eyes", where a multitude of memories from life events are recalled almost instantaneously. Researchers present theories on why this phenomenon may occur.
53% of dreams can be traced to memories, and of those, 50% are linked to memory sources of multiple previous life events. Additionally, 26% of dreams are associated with impending events. Future-orientated dreams become more prevalent during deeper stages of sleep.
A new study reveals people are able to recall memories from events that occurred when they were two and a half years old. The findings counter previous research, which reported the earliest memories usually form after the age of three and a half.
Disregarding lab animals' circadian rhythms can hamper reproducibility, validity, and reliability of research, researchers say.
Researchers have identified three biomarkers in blood samples that confirm the link between exercise and improved cognitive function in older adults.
As novel visual patterns become familiar, stark changes occur in the visual cortex. Gamma rhythms give way to low-wave beta waves, and the neural activity switches from PV neurons in favor of inhibitory SOM neurons.
Rat study reveals place cells in the hippocampus have the same patterns of activity whether they correctly, or incorrectly recall a memory. However, when the memory is incorrect, the activity begins later and is slower.
Mouse study reveals intermittent fasting improves long-term memory retention and promotes hippocampal neurogenesis. The findings could help to slow cognitive decline in older adults.
