Thync is a consumer product. And that's exactly how we're reviewing it – much like we would a new iPhone or laptop. We share our experience and make our recommendations, but we aren't writing any research papers or conducting any double-blind studies on it (though the company does link to some of those on its website).

After using Thync every day for the last week and a half, I'm convinced that it's one of the most exciting new tech products of 2015. Like taking a hit of Mary Jane, it can push me from an anxious, over-thinking mood to one where I'm cool, collected and laid-back like a THC-infused Rastafarian. And if I'm feeling sluggish or unmotivated, Thync can also peel that layer away, like the sun burning a morning fog off of my consciousness.

I heard about the brain-mod crowd a couple years ago at the New York Maker's Faire. A team from DARPA gave a talk on an electro-stimulation cap they said was meant to fight Post-Traumatic Stress Disorder (PTSD) in veterans. This seems to follow. Has anyone from Soylent experimented with trans-cranial electro-stimulation?

    One of the aspects of tDCS is its ability to achieve cortical changes even after the stimulation is ended. The duration of this change depends on the length of stimulation as well as the intensity of stimulation. The effects of stimulation increase as the duration of stimulation increases or the strength of the current increases.[4] The way that the stimulation changes brain function is either by causing the neuron’s resting membrane potential to depolarize or hyperpolarize. When positive stimulation (anodal tDCS) is delivered, the current causes a depolarization of the resting membrane potential, which increases neuronal excitability and allows for more spontaneous cell firing. When negative stimulation (cathodal tDCS) is delivered, the current causes a hyperpolarization of the resting membrane potential. This decreases neuron excitability due to the decreased spontaneous cell firing.[5][12]

    Neuroplasticity refers to the ability of the brain to change throughout life based on experiences. The way that transcranial direct current stimulation functions could be due to the plasticity concepts of long term potentiation (LTP) and long term depression (LTD) since the two share some basic similarities. Long term potentiation is the strengthening between two neurons while long term depression is the weakening between two neurons. These effects are achieved mainly through an alteration of synaptic transmission ability. LTP enhances transmission and LTD hinders transmission. Likewise, tDCS stimulation involves the alteration of synaptic transmission ability through modifications of intracellular cAMP and calcium levels. Also, both LTP, LTD, and the effects of tDCS are protein synthesis dependent. It is for these reasons that LTP and LTD are proposed mechanisms of the function of tDCS.[5][12]

    So, according to Wikipedia people think this works because it physically changes how well the neurons in your brain conduct electrical signals.

    The truth is we don't know what "well" is. Something that changes your mood today might be something that drives you to a different personality later on, or even gives you cancer or Alzheimer's in the long run. Time will tell. In any case, I can't grasp the reasoning behind better electrical conductivity improving mood. If anything, I imagine it would have an effect closer to making you feel time passing slower yet getting tired in less "real-world" time - after all, it's pretty much an overclock. Now, how would an organ fare with such an overclock, that is the question...

    In any case, I vape with ecigs to replace real tobacco, so I'm all about the lesser evil. This is something I would try if I really had chronic trouble keeping a decent mood.

      In this case "well" is merely referring to the physical and objective degree of electrical conductivity, not as a judgement of the overall brain state itself...
      This isn't like over-clocking the whole brain, rather modulating the relative strength of different "circuits" so as to produce a different neurocognitive profile, without any reference to an unknown hypothetical universal ideal (which I don't think even makes sense, tbh).
      Indeed, these kinds of modulations are known to have effects of both improving or impairing particular sorts of moods or performance capacities, often involving mutual trade-offs between different ones.
      The desirable use of stuff like this is basically to aid in transitions between states as appropriate or desired in a given circumstance, and/or to help adjust habitual tendencies.
      Think of it more like: sometimes you want better visual thinking to solve a geometry problem so you shift resource utilization toward your visual centers at the expense of the verbal ones. Later, you want to solve a word problem so you do the opposite. At another time you just want to relax and zone out, so you down-regulate some excitable part that you might prefer to up-regulate some other time you want to be more motivated and attentive.
      Long term effects are more a matter of how practice reinforces whatever is practiced, so any time you use this system to up-regulate a particular circuit you improve that circuit's ease and degree to which it can be up-regulated in the future, even without the external system. Likewise with down-regulation tending towards inhibiting the ease and degree to which it can be up-regulated / increasing the ease and degree to which the circuit can be suppressed. This can have benefits or detriments depending on specifically how you tend to utilize it.
      This is all roughly speaking, and from a layman's potentially flawed understanding, of course.
