While we’re on the subject of “hacking the human mind“, it looks like there is renewed interest in psychosurgery. The link goes to an article about deep brain stimulation for alcoholic cravings, PTSD, and depression!
People have been triyng to control psychiatric conditions with surgery since the days of the prefrontal lobotomy. Electrical stimulation has the advantages of precision and reversibility. However, as with any neurosurgical procedure it relies upon localizing an unwanted symptom to a specific location in the brain. For example, deep brain stimulation works for Parkinson’s because the disease is localized to the basal ganglia.
No matter how much funding you throw at electroneurology, it won’t do any good if an unwanted emotion or compulsion is spread out over a large area of the brain. It remains to be seen how well localized things like alcoholism and PTSD are.
