Halo Sport is designed to make your training or practice more efficient by improving your brain's natural plasticity. By applying a mild electric field to the motor cortex, Halo's Neuropriming technology induces a state of "hyperplasticity." When you train in a hyperplastic state, the brain's normal fine-tuning process occurs more rapidly — meaning better results from each practice rep.

To understand how Halo Sport achieves these benefits, it's important to understand how neurons communicate with each other. This graph demonstrates what a neuron does when it sends a signal. The grey line is a non-primed neuron — it starts at a baseline, and stays there, not sending any signals until it starts to receive information from other neurons (the first bump). Over time, signals come in from other neurons and the line rises. If the neuron receives enough input within a short period of time, it crosses an electrical threshold and sends a signal called an action potential. This is how neurons communicate with each other.

The green line represents a neuron primed for hyperplasticity, with an elevated starting point. Similar to the unprimed neuron above, as signals come in, the line again rises until it reaches the electrical threshold and fires an action potential. The difference is that it now takes less input to trigger the neuron to send a signal. This means that more signals will be sent for a constant amount of input, and — even more importantly — nearby neurons will be 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.
