UCLA researchers report sleep deprivation prevents neurons from correctly connecting with each other, resulting in temporary cognitive lapses in visual perception and memory.
Study reports declarative memory depends upon conscious knowledge of what has been previously learned. Researchers discovered conscious knowledge is compromised in those with damage to the hippocampus. The findings shed new light on how the hippocampus controls the process of memory.
The medial temporal lobe and medial parietal cortex work in tandem to assist in the recognition of faces and places.
A new study reports people who sit down too much during middle to older age show signs of thinning in the medial temporal cortex, an area of the brain associated with the formation of new memories.
Communication between the medial temporal lobe and prefrontal cortex determines how our experiences become memories. As the brain areas mature, the precise way they interact allows for the better formation of long-term memory.
Neurons in the medial prefrontal cortex respond more to loss than to gain. Avoidance of risk-taking is affected by an area of the hippocampus that is associated with memory and anxiety. The findings suggest a close relationship between memory processing and decision making when risk is present, especially in stressful situations. The fresh insights might help guide new psychiatric therapies for disorders marked by excessive avoidance, such as anxiety, and depression, and also mania and addiction, where excessive risk-taking is a common feature.
Imagination helps us act altruistically, a new study reports. When we see others in trouble, we imagine how we can help before acting. Researchers implicate the medial temporal lobe subsystem in guiding our prosocial behaviors.
A new study helps to untangle the memory web by shedding light on how neurons in areas of the brain associated with memory provide long term coding of associations between concepts.
