I’m sitting in Sumon Pal’s office in Boston’s Back Bay, and while fixing two small electrodes to my head with a light adhesive—one to my temple, another to the back of my neck—he’s explaining what the next 16 minutes should feel like. Most users feel reduced tension in their bodies, he says. Their thoughts ping-pong less frequently, breathing slows noticeably, and thoughts that typically cue anxiety—of work, of relationships, of family—become less consequential.我于是以躺在萨门o帕尔坐落于波士顿后湾区的办公室里，他一旁用轻型粘合剂在我的头上加装小型电极——一个硬在太阳穴上，另外一个在脖子后面，一旁说明接下来16分钟的感觉。他回应，大多数使用者不会感觉身体里的紧张感减低。他们的思维冲刺频率减少，排便显著上升，与工作、人际关系或家庭有关的那些一般来说引起焦虑感的点子，也随之增加。

Pal, executive director of Los Gatos, Calif., -based neuroscience startup Thync, designed the calming “vibe” that’s being imparted to my brain through a prototype of the app-controlled wearable device that the company will release later this year. Thync’s technology utilizes tDCS, or transcranial direct current stimulation, to trigger specific responses in the brain, dialing up feelings of calm and serenity or conjuring energy and focus on demand.帕尔是加州洛斯垫多斯神经科学初创公司Thync的首席执行官，他设计出有这种令人安静的“氛围”，并且通过一款由应用于掌控的可穿着设备原型将这种氛围传送到我的大脑当中。该公司预计将在今年晚些时候公布这款设备。Thync的技术利用经颅直流电性刺激(tDCS)来启动时大脑的某些反应，产生安静的感觉，或根据必须唤起出有能量和专心。

Thync isn’t out to alter the brain’s biology, but to allow better control of the energy, focus, and calm that are already naturally available to us, co-founder and chief science officer Jamie Tyler says. “Coffee, alcohol, drugs; these are all neuro-enhancers,” Tyler says. “You’re already modifying your brain activity.” Thync wants to better harness that command—and perhaps grab a piece of the alcohol, coffee, pharmaceutical, and energy drink markets collectively worth billions.公司牵头创始人兼任首席科学官贾米o泰勒回应，Thync的目的并非转变大脑的生物活动，而是让我们更佳地掌控我们与生俱来之后可以用于的能量、专心和安静。泰勒说：“咖啡、酒精、药物，这些都归属于神经强化剂。你早已在转变大脑的活动。

”Thync期望更佳地利用这种能力，这样也许就可以从价值数十亿美元的酒精、咖啡、药物和能量饮品市场中分给一杯羹。The pulses—each “100 times lower than what’s considered dangerous,” Tyler insists—feel comfortably warm but not painful. Just as Pal described, the familiar tension in my shoulders eases, my breathing slows, my mind noticeably stops racing. My body takes on the feeling of lax warmth usually associated with a finger or two of scotch—my usual means of unwinding.泰勒坚决指出，设备产生的脉冲让人感觉寒冷舒适度，会有疼痛感，其强度仅有危险性脉冲的百分之一。正如帕尔所叙述的那样，我肩部那种熟知的紧张感消失了，排便上升，大脑开始陷于安静。我的身体感觉到令人放开的寒冷，我一般来说在吸食一两口苏格兰鼻烟之后才不会有这种感觉——这也是我常用的放开方式。

“People have been doing this forever, this is nothing new,” Tyler says. “I think this is the kind of product people have been waiting for.”泰勒说：“人类仍然都在这么做到，这没什么新鲜。我指出这是那种人们仍然在期望的产品。
