This study, published in Nature by the Baylor College of Medicine research team, challenges the traditional theory that only neurons, via engrams, are involved in memory formation and retrieval. The authors present evidence that astrocytes, non-neuronal glial cells, also participate in this process, working in concert with neurons to store and retrieve memories. The press release accurately reflects the key points of the study, highlighting this paradigm shift in the neuroscience of memory. 

In terms of the quality of the study, it appears to be supported by a rigorous design and advanced methods for assessing the activity and role of astrocytes. However, it is important to consider confounding factors and limitations inherent to the experimental model. This discovery opens up a promising field in the study of memory mechanisms and suggests potential applications in the treatment of memory disorders.
