Back to the science

Yes, tDCS is safe.

tDCS improves cycling endurance by 20%

TASK: This placebo-controlled study tested the impact of tDCS on time to exhaustion at 80% max power on the bike.

RESULTS: The tDCS group (green) cycled for 20% longer than the placebo group (grey) after just one stimulation session.

How does transcranial direct current stimulation (tDCS) work?

tDCS delivers a constant, low current to the brain through electrodes on the scalp.

tDCS activates neurons in the target region, accelerating the learning process in the brain.

Benefits vary from sports performance to learning, depending on where the electrodes are placed.

How can transcranial direct current stimulation help me?

  • Fine motor skills
  • Strength
  • Endurance

More than 4,000 peer-reviewed studies covering 100,000 stimulation sessions support the safety and efficacy of tDCS.

tDCS induces a state of hyperlearning

  • Plasticity is the brain's ability to strengthen connections between neurons and even form new pathways.
  • tDCS induces a state of hyperplasticity, during which this process happens faster.
  • This graph compares a neuron's signaling normally (grey) to with tDCS (green).
  • With tDCS, it takes less external input to trigger firing, so more signals are sent and nearby neurons are more likely to fire together.
  • Because plasticity is driven by neurons firing together as they send and receive signals, this leads to hyperplasticity — better, faster fine-tuning of your brain's neuronal connections.
