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.
Some words are far more memorable than others. Researchers discovered our memories are wired into neural networks that allow the brain to search for these memories, much like the way search engines track down relevant information.
The medial temporal lobe and medial parietal cortex work in tandem to assist in the recognition of faces and places.
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.
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.
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.
UCLA researchers report sleep deprivation prevents neurons from correctly connecting with each other, resulting in temporary cognitive lapses in visual perception and memory.
Whether we are consciously aware of seeing a familiar face and object or not, our brains actively notice. A new study sheds light on the nature of conscious perception.
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.
