This paper changed my life: A technical breakthrough for memory studies

In a 2007 Science paper, Mark Mayford and his colleagues found that some neurons activated during learning are also recruited during memory retrieval. Noelia Weisstaub shares how this study and others drove an era of great progress in tool development.

Brain Flows book cover

‘Brain Flows: How Network Dynamics Compose the Human Mind,’ an excerpt

In his new book, published today, Michael W. Cole examines how the movement of neuronal activity between neuronal populations shapes free will, intelligence and creativity. In this excerpt from Chapter 1, Cole explores why activity flows could unify efforts to map brain functions and connectivity.
