Study reveals hippocampal maps predict context-dependent behaviors.
New memories are laid down via different mechanisms in older mice compared to younger mice. Additionally, synaptic changes linked to new memory formation were harder to modify in older mice.
Study reveals the hippocampus may overlay existing mental maps with information about reward and hazard derived from food found in specific locations.
After creating a memory in a context, engram cells encoding the memory in the hippocampus become more excitable when the context is repeated a short time later, researchers report.
Researchers have identified a cellular pathway that encodes memories by strengthening specific neurons.
Researchers use virtual reality to discover how the brain assembles contextual memories.
Adjusting levels of KYNA can have a significant effect on schizophrenia symptoms, a new study reports.
According to researchers, a single dose of methylene blue could enhance short-term memory and attention.
Injections of IL-33 appear to rescue contextual memories and reduce amyloid beta deposits in mouse models of Alzheimer's disease.
Researchers have identified a cellular circuit that helps the brain remember which environments are safe, and which pose a danger.
A new study points to previously understudied area of the brain as essential for forming the basis of contextual memory.
