What Neuroscientists Now Know About How Memories Are Born and Die

Where, exactly are our memories? Are modern media destroying them? Could we erase them if we wanted to?

At one time, neuroscientists believed that there must be a “seat” of memory in the brain, something like a room with a door marked Memory. They settled on two structures called hippocampi, on either side of the brain’s base. The illustration shows the the hippocampus of the right hemisphere (public domain). But memories turned out to have no fixed address. Neuroscientist Matthew Cobb, author of The Idea of the Brain (2020, excerpt here), tells us, But the hippocampuses are not the site of memory storage. Rather, these brain regions are the encoders and the routes through which memory formation seems to pass. The memories that are processed by the hippocampuses seem to be distributed across distant regions of the brain.…

Neuroscience evidence suggests that our real problem isn’t with remembering things but finding our memories when we need them

One of a pioneer neurosurgeon’s cases featured a patient who could, unaccountably, speak ancient Greek. The explanation was not occult but it was surely remarkable for what it shows about memory.

How Can Consciousness Be a Material Thing?

Maybe it can’t. But materialist philosophers face starkly limited choices in how to view consciousness
In analytical philosopher Galen Strawson’s opinion, our childhood memories of pancakes on Saturday, for example, are—and must be—"wholly physical." Read More ›
