Trans-cranial direct current stimulation (tDCS) sounds like it’s straight from the laboratories of a mad scientist-well in some respects it is. The exclusive, somewhat secretive world of psychiatry has used electricity as a form of ‘therapy’ for decades. Through applying electrical current directly to the brain Psychiatrists attempt the reconstruction of reality as experienced by their ‘patients’. The late Professor Thomas Szasz, himself a psychiatrist was a fierce opponent of such practices arguing that mental illnesses are not real diseases, except for those with quite specific physical symptoms like Alzheimers and Dementia. He claimed-rightly so I think-that there are no objective, verifiable approaches to identifying whether a mental illness is present or not. It is almost impossible to falsify the research findings of psychiatry, for the most part they become lost in a maze of data and statistical analysis with meaning hard to locate when applied to standardized views of acceptable human behavior.
Most if not all psychiatric diagnoses are based upon a perceived understanding of what is real and what is considered acceptable thinking as acted out within the realm of private, personal and social behavior in a culture or society. In his classic book on self-development and independence, ‘If You Meet the Buddha on the Road Kill Him’, Sheldon B Kopp tells the insightful, witty and perceptive story about a man dressed in a white sheet and a funny pointed hat, speaking gibberish, being arrested by the police in a US town. He is taken off to a psychiatric institution, evaluated and assessed as quite mad. The following morning a dozen or so other similarly dressed persons appear at the institution while speaking the same strange language and seeking their lost friend. The captive man was eventually released into their custody. The moral of the story, according to Kopp, is that one man exhibiting strange behavior is a lunatic while a group of them represent an acceptable, if not slightly odd, community. And this seems to be the ever present danger within 21st century humanity today.
A recent online report (Young, 2014) claims that neuroscientists are able to change the brain function of healthy people through electric shock stimulation. Furthermore, the US military are testing this on their soldiers to improve and enhance their ability to react especially under stress and when deprived of sleep (Young, 2014). Researchers into this brave new world of mind-body manipulation observe the reactions of the brain through infra-red imaging. They stimulate the motor cortex and inhibit the prefrontal cortex to manipulate human cognitive processes and the accompanying physical responses. It is claimed that the results are extraordinary and improving performance and researchers maintain the effects last long term. According to the report researchers are also investigating ultrasound and laser light to manipulate brain wave patterns. This kind of research on human subjects raises serious ethical as well as medical concerns, especially around the long term effects and whether or not as the subjects age any long term damage will emerge. And whether the very essence and nature of a human being-our consciousness-should be manipulated to the extent that our actions are predetermined and we lose our capacity to exercise our free will. Perhaps we’ll find out in a similar fashion as we did when we had humans observe those nuclear tests in the deserts of the US and Australia during the 1950s when a horror was unleashed on humanity. It really is a mad, mad, mad, mad world!
