4. Near Death Dissociation

This story is about a Substack essay reviewing whether dissociation and fantasy proneness explain near-death experiences. The piece summarizes evidence that people who report near-death experiences often score higher on dissociation scales and on measures of fantasy proneness, which is one pillar of the NEPTUNE model that treats these experiences as a defensive altered state.

Reddit discussion

2. Knowledge Uploading

This story is about an r/neuro discussion asking whether knowledge could ever be uploaded into the brain the way files are copied onto a computer. The original question frames the issue in terms of brain-computer interfaces and asks whether direct information transfer would count as understanding, or whether learning still depends on neuroplasticity and practice.
