Part 4/9:
Fundamentally, skill acquisition and improvement depend on neuroplasticity—the brain's ability to form new neural pathways through repetition and learning. Transcranial direct current stimulation (TDCS) leverages this principle by applying a mild electrical current to specific parts of the brain, notably the motor cortex, to accelerate neuroplastic changes.
This technology isn't new but has recently become accessible to consumers through wearable devices. Halo Neuroscience, a pioneer in this field, offers brain stimulators that can be worn during training sessions. Just 20 minutes of stimulating the brain before practice can extend a window of heightened neuroplasticity for up to an hour, making learning faster and more effective.
