Hmm.<p>While the ethics of using this technology &#x2F; vector attack for <i>advertising</i> is hardly a difficult question, one thing does amuse me.<p>Nary a thought in this thread at what other little nasties this technology can be used for (I&#x27;d suggest looking into &quot;mosquito&quot; deterrents that can be used against teenagers).<p>Here’s some links – whilst you might not immediately realize their connection to this, I’m fairly sure others out there have.<p><i>The hippocampus, which receives a major cholinergic input from the medial septum&#x2F;diagonal band3, is important in memory4,5 and exhibits network activity at 40 Hz during relevant behaviours6. Here we show that cholinergic activation is sufficient to induce 40-Hz network oscillations7 in the hippocampus in vitro. Oscillatory activity is generated spontaneously in the CA3 subfield and can persist for hours. </i>

We found that phasic activation of these neurons was sufficient to drive behavioral conditioning and elicited dopamine transients with magnitudes not achieved by longer, lower-frequency spiking. These results demonstrate that phasic dopaminergic activity is sufficient to mediate mammalian behavioral conditioning.</i>

DTX reduced the signal-to-noise ratio (SNR), defined as the ratio of probability to fire in response to the EPSG and the probability to fire spontaneously in response to noise.</i>
