I am a luddite by nature, so the ethical and hypothetical questions raised in the documentary Hunting for Hedonia make me absolutely terrified of the future. That’s not exactly what I expected from the film, since so much of its subject is rooted in the past. The central topic of this documentary is research in the field of Deep Brain Stimulation – wherein the physical pleasure centers of the human brain are activated by electric pulses via surgically inserted wires. It’s a technology that was first developed in 1950s New Orleans by Dr. Robert Heath of Tulane University. Seeking to depopulate the grim mental institutions of the era that treated patients like prisoners, Heath and his team experimented with this radical technology to cure the most hopeless cases of clinical depression and put an end to the practice of lobotomy. Their success led to more exploratory applications of the tech that immediately crossed major ethical boundaries and retroactively damaged the reputation of the research among their peers. Now, modern neurosurgeons are rediscovering the benefits of DBS independently of Heath’s forgotten, discredited research and finding entirely new, complexly fucked up ways to abuse the tech – hinting at a terrifying near-future we’re somewhat helpless to avoid.
The horror and the wonder of DBS is that it really works. Patients suffering from extreme, incurable cases of suicidal depression, addiction, OCD, and Parkinson’s have had their lives saved by this experimental frontier of neuromodulation. This combination of psychology & neuroscience that engages the physical location of pleasure in the brain (Hedonia) has produced unignorable results in patents who have been failed by medication & talk therapy in the past. That doesn’t mean DBS is a perfect, foolproof science, though. Side effects in “cured” patients have included unexpected increase in rage & loss of impulse control, suggesting that these neurosurgeons are tapping into capabilities of the brain that we don’t yet fully understand. That’s where the terrifying vision of our near-future abuses of DBS come in, as excited, capitalistic interest in the re-emerging field is getting ahead of the technology’s currently limited applications. There’s money to be made in being able to alter the functions of the human brain – cosmetically, recreationally, militaristically, and so on – that raise dangerous ethical questions not yet fully ironed out by its application in the medical field, where it’s actually warranted. The scary thing is that these boundaries have already been crossed in the past, as Heath & crew contributed to nefarious DBS applications like participation in MK Ultra & gay conversion “therapy” (read: abuse) and yet no one seems to have learned from their unforgivable mistakes.
As a documentary, Hunting for Hedonia is most valuable for its ability to explain the full scope of DBS’s history in concise layman’s terms. It covers the horrific past of its abuse, the promising present of its success in the therapy field, and the terrifying future of its rapid, unavoidable escalation in a modern capitalist paradigm. Considering its detached narration from the expertly icy Tilda Swinton and its innocuous score, I don’t think the film necessarily leans into the eeriness of its subject in a flashy or deliberate way. If anything, it often plays like a well-behaved, informative BBC documentary instead of a work of art. Still, I was thoroughly creeped out by its subject’s ethical implications for our insidiously techy future, to the point where its 1950s lab footage & Rotoscope animations felt like vintage sci-fi horror from the drive-in era. That feeling of unease was only amplified by catching a screening of the film at this year’s New Orleans Film Festival, where local neurosurgeons familiar with Dr. Heath’s research were muttering to each other about what a genius he was before the lights went down. I felt like running around the theater shouting “Don’t you see what he’s done?! Stop before it’s too late! Soylent Green is people!” in protest. Then again, DBS has obviously already helped people in desperate need and my luddite skepticism of its grim implications for the future are so far hypothetical in nature. That screening felt like an ethical Litmus test, and it’s unclear to me which side of the divide failed it.
