Questions

What is tDCS and how does it work?

tDCS (transcranial direct current stimulation) applies a weak electrical current — 1 to 2 milliamps — to the scalp through electrodes. This modulates the firing threshold of nearby neurons without causing action potentials. At the DLPFC (sites F3/F4), a 20-minute session produces a post-stimulation performance window lasting approximately 90 minutes.

Is tDCS safe for home use?

Yes, at standard parameters (1–2 mA). Bikson et al. (2016) reviewed 33,200 sessions with no serious adverse events. Skin tingling at the electrode site is the most common effect. Three absolute contraindications apply: active epilepsy, implanted cardiac devices, and active medications that significantly lower seizure threshold.

What does tDCS do to the brain?

tDCS modulates cortical excitability — anodal stimulation over the DLPFC shifts neurons toward their firing threshold, supporting working memory and executive function when paired with concurrent cognitive work. Dedoncker et al. (2016) found a small but real effect (d ≈ 0.3–0.4) on reaction time across 61 sham-controlled studies.

Can tDCS improve working memory?

Conditionally yes. The effect requires concurrent cognitive engagement — tDCS alone without an active task shows no reliable benefit (Mancuso et al., 2016). When paired with cognitive work, a small but statistically real effect is documented (Dedoncker et al., 2016, d ≈ 0.3–0.4). Approximately 30–40% of individuals may be non-responders.

What are the contraindications for tDCS?

Absolute contraindications: active epilepsy or seizure disorder, implanted cardiac devices (pacemakers or ICDs), and active medications that significantly lower seizure threshold. Additional precautions for pregnancy, active skin conditions at electrode sites, and metal implants near the head. Sychedelic enforces all contraindications via in-app screening before every session.

It doesn't fire neurons. It changes who does.
