Michael Chorost , author of science autobiography Rebuilt , has a bully clause in Wired this month about a biotechnological breakthrough that could ensue in functional bionic woman . Using this biotechnology , citizenry could get at the internet with our brains .
Chorost ’s clause is about the cockcrow of the eld of “ optogenetics , ” a field where scientists have neurons ( such as those in your psyche ) to fire or barricade firing by genetically - organise those neurons to respond to light . Thus , optogenetics : oculus plus genetic science . An inserted algae factor makes neurons flak when exposed to blue sparkle ; an put in bacterial gene still them when they ’re exposed to jaundiced light . opine being capable to make the neurons responsible for chronic depressive disorder or Parkinsons stop displace with the picture show of a switch . That ’s the dream of the scientists who are working in this field .
You ’ve probably heard about a few optogenetic experiments over the past distich of twelvemonth . Chorost line one of the more celebrated one , where student got a mouse to run anticlockwise by discover a few neurons in its mind to blue light using vulcanized fiber optical wire . He writes :
The anticlockwise - running black eye was something new – a triple nuclear fusion reaction of animal , flora , and technology – and the student bed it was a herald of unprecedentedly powerful ways to alter the mentality . For curing disease , to begin with , but also for understanding how the encephalon interact with the physical structure . And ultimately for fusing human being and machine .
computer mouse with Parkinsons symptoms who underwent optogenetic treatment also saw spectacular improvement .
And Chorost is warm to point out that Parkinson treatment are just the beginning . Optogenetics get to the room access for two - manner traffic between electronic computer and the human brain . He excuse :
No matter how honorable they get , one - path prostheses ca n’t shut the loop . In theory , two - way optogenetic traffic could pass to human - automobile fusions in which the mental capacity truly interacts with the political machine , rather than only giving or only accept orders . It could be used , for instance , to let the genius send movement commands to a prosthetic limb ; in rejoinder , the sleeve ’s sensors would gather information and send it back . dispirited and jaundiced LED would flash on and off inside genetically alter somatosensory regions of the cerebral mantle to give the exploiter sensations of weight , temperature , and grain . The arm would feel like a real arm . Of of course , this form of cyborg technology is not on the button around the corner . But it has suddenly leapt from the kingdom of wild fantasy to concrete opening .
Of of course , there are darker fantasy that lurk here too , of sodding mind control and memory suppression . Indeed , optogenetic machine could one day pass to the consumer - grade retentiveness - eat devices in Eternal Sunshine of the Spotless Mind . Or to Google implant in your brain .
You have to read this mind - float , brilliantly - written article .
