The Biology of the Engram and the Ethics of Neurotechnology | Analysis

The article analyzes the nature of memory not as a static archive, but as a dynamic biological organization (engram) that evolves through representational drift. The author emphasizes the prospective function of memory – it serves not so much to reproduce the past, but to simulate future events and organism adaptation. A key point is the transition from observation to causal interference in the brain thanks to optogenetics and projects such as Project X. The ability to selectively activate neuron populations opens the way to technical manipulation of memories, which raises fundamental questions about individual identity and the ethics of using neurotechnology in the context of mental privacy and human agency.
