Astrocytes were hardly studied in the past in the context of higher brain function, and if they were it was as disruptors of it. In recent years there is a growing interest in how astrocytes are involved in memory, and I will talk about how they are involved in recent and remote memory with activity- and projection- specificity. I will then present a new role of astrocyte in encoding (themselves!) environmental data, specifically reward location. I will present the methods, and how important it is to work on awake behaving animals.
