Direct Interactions Between the Human Insula and Hippocampus During Memory Encoding

The Neuroscience of Identity and Our Many Selves

You are not one self, but many. Psychology and neuroscience now agree that our identity is made of parts, shaped by brain networks that shift with emotion, memory, and context.

Direct interactions between the human insula and hippocampus during memory encoding

The hippocampus is critical for encoding episodic memories, but how it interacts with cortical regions during this process remains unclear. In this study, 16 participants with implanted electrodes in the insula (217 sites) and hippocampus (131 sites) viewed emotionally valenced words and attempted to recall them. During encoding, one subset of insular neuronal populations showed changes in aperiodic activity that predicted successful recall. The…

Key neurophysiological mechanism in human memory formation identified

A research team has identified, for the first time in humans, and in a realistic environment, a key neurophysiological mechanism in memory formation: ripple-type brain waves—high-frequency electrical oscillations that mark and organize the different episodes or fragments of information that the brain stores as memories.

Atkinson and Shiffrin’s (1968) influential model overshadowed their contemporary theory of human memory

Although every student of memory knows about the Atkinson-Shiffrin (1968) model, few know that it was advanced as a general-purpose modeling framework…
