Episode notes
Past Abuse Of Pleasure Stimulation
- Historical experiments electrically stimulated pleasure centers and attempted behavior change in the 1960s.
- One infamous case tried to alter sexual orientation via stimulated reward pairing and failed, harming the field's reputation.
Habituation And Implant Longevity Limit Abuse
- Repeated artificial stimulation may lose effectiveness due to habituation.
- Implant lifetime is short now, so continuous pleasure stimulation would require repeated surgeries or replacements.
All Cells Carry Electrical Identities
- Non-neuronal cells also have characteristic membrane voltages linked to identity and development.
- Depolarized cells near zero mV (like stem cells) are more plastic and can become many cell types.
