Neuronal Ensemble Memory Is Constantly Updated
The concept of memory is a fundamental component of how humans and other organisms function. Memory is a complex and dynamic process that can involve multiple parts of the brain. Scientists are now starting to uncover the processes that underlie the formation of new memories and how memories are updated over time.
Recent research has focused on the underlying mechanisms of memory updating, particularly surrounding the concept of neuronal ensemble memory. This type of memory is a form of short-term memory that is created when multiple neurons are recruited to encode or recall information. Using this process, novel experiences or information can be encoded into memory and existing memories can be retrieved.
A recent study published in the journal eLife revealed that memory updating is dependent on the dynamic recruitment of neuronal ensembles. This study found that changes in excitability could drive a process of updating memory. The results showed that when excitability was increased, the neuronal ensemble was more active and more easily recalled than when excitability was decreased. These findings suggest that neuronal ensemble memory is constantly updated on the basis of changes in brain excitability.
Another study published in the journal AAAI focused on the concept of dynamical memory updating using a transformer-style relational reasoning network. This work found that when additional information is available, it can be used to update existing memory in a dynamical manner, allowing for more efficient memory recall. In addition, the study showed that when memory resources were redistributed, memory recall performance improved.
The results of these investigations suggest that neuronal ensemble memory is constantly updated. The ability to update existing memories allows for reliable and efficient memory recall, which is an important feature of the memory process. Understanding the mechanisms of this update process is important for understanding the capabilities of memory and can also be used in the development of artificial intelligence.
