Understanding the Hippocampus and Memory

The video explores the role of the hippocampus in memory formation, consolidation, and spatial navigation. It begins by discussing the hippocampus's involvement in retrieving past experiences and its location within the brain's temporal lobes. The video then explains two types of amnesia: anterograde and retrograde, using the case study of Henry Molaison. It delves into how the hippocampus forms new explicit memories, consolidates them into long-term storage, and its role in spatial memory through place cells. The hippocampus is described as a mental time machine, with its name derived from the Greek word for seahorse.
