It's increasingly agreed upon that tech is changing how our brains work. So, why not lean into it? The market is getting busier with devices that want to tap into our brains with the promise of doing a variety of things including improve athletic performance, fight pain, calm us down and even help speed up the process of learning new skills.

Many of these devices are based on neuroscience, an area of research with a storied history that stretches as far back as Ancient Egypt. Thanks to recent developments it's firmly on the wearable tech agenda with a host of innovative startups now taking full advantage.

So what exactly is neuroscience, is it safe and who's using it? We try to answer all those questions and more below.

What is neuroscience?

Tapping into the brain: Neuroscience wearables explained

So let's break down what we mean by neuroscience. Check in on any reputable medical or science resource and it will tell you that neuroscience or neural science is all to do with the study of the brain and the nervous system.

It's about getting a better understanding of how the nervous system operates by examining how neurons (nerve cells), essentially the building blocks of the nervous system, talk to each other and generate certain behaviours and cognitive functions. When we talk about cognitive functions we're talking about things like the way we acquire information and knowledge.

Historically, neuroscience has been closely aligned with biology but it now overlaps with disciplines that include mathematics, psychology, chemistry and linguistics. Modern neuroscience is broken down into a whole host of different branches from behavioural science, which looks at how the brain affects behaviour to neuroimaging, which diagnoses disease and assesses the health of the brain. There's a whole lot going on in the neuroscience space right now.

Advances in many of the disciplines that now cross over with neuroscience have enhanced what is currently capable in terms of exploring our nervous systems. We're getting a much better understanding of how the nervous system works and uncovering more about what it's actually capable of.

So how does that apply to wearables?

What we're seeing is a growing trend in brain-training wearables that offer non-invasive methods of neurostimulation. This means that small amounts of electricity are sent via micro electrodes to specific parts of the brain to stimulate specific nerve cells in the brain.

This type of electrical brain stimulation has been used in the past to help diagnose disorders of the brain or even provide treatment for post-traumatic stress disorders. What we are now seeing are connected wearables, of varying medical and consumer health grades, that are putting this control into regular people's hands to improve brain performance for a whole host of reasons.

Meet the neuroscience wearables

Muse 2

Tapping into the brain: Neuroscience wearables explained

Canadian startup InteraXon's followup to its first headset, the Muse 2 is a wearable aiming to help users maintain calm and focus. It pairs with a smartphone app to create your own personal meditation assistant, helping to plan sessions and coaching you to help you find mindful peace. If you're a fidgeter, the Muse 2 will even spot that motion and help you to quell your anxious instincts.

Halo Sport 2

Tapping into the brain: Neuroscience wearables explained

Halo Neuroscience is a veteran of the wearable neuroscience scene. It has been making neuroscience wearables for years, culminating in the Halo Sport 2. It's a headset aimed squarely at serious athletes but also being embraced by other industries, including the US Navy Seals.

Halo aims to improve physical attributes such as strength, speed and endurance, as well as mental acuity and speed of learning. It does this through what it calls neuropriming. This involves sending a small level of electrical current to the user's brain via Primers (electrodes), which are fitted inside of the headphones. We tested the headset out, using our darts skill as a test-case, and found it an interesting addition to our training.

Quell 2.0

Tapping into the brain: Neuroscience wearables explained

This wearable strap that is worn on the upper part of the leg uses a kind of neurostimulation that has been around for some time, but is now available in mini wearable form. It uses miniaturised TENS (transcutaneous electrical nerve stimulation) technology to reduce the perception of pain, delivering tiny electrical impulses that help drown out pain signals to the brain and offer pain relief. Unlike many of the devices mentioned here, the Quell wearable is FDA approved and it can be used while you're sleeping.

Another gentle option is offered by Flow, a headset designed to treat depression without the need for medication. Approved for use and sale in the UK, Flow uses Transcranial Direct Current Stimulation (tDCS) in combination with a program of therapy powered by AI. After six weeks, users enter a follow-up phase. Flow has been backed up by research papers, an important vote of confidence in this sort of technology.

Unlike Halo, the TouchPoints wearable embraces the stimulating technique to help you de-stress (in just 30 seconds apparently), improve focus and get a better night's sleep. TouchPoints can be worn around the wrist or clipped onto clothing and then uses its Bi-Lateral Alternating Stimulation Tactile (BLAST for short) technology. This is a new method of neuroscience technology that sends alternating vibrations and aims to reduce the amount of excess brainwaves that translate into anxiety or stress.

But does it work and is it safe?

So, this is the big thing. If you turned around to someone and asked them to try this wearable that tinkered with your brain, they're probably going to be sceptical if it works and if it's even safe to try out. Jump onto the websites of the likes of Muse or Halo Neuroscience and you'll read about the years of research and medical studies that proves this kit is legit, though the potential benefits of brain stimulation still divides neuroscientists today.

Most of the companies mentioned above do not require measures like FDA approval because they are 100% non-invasive devices that are considered lifestyle devices as opposed to medical devices. Perhaps in future, we will see more standards in lifestyle-focused wellbeing tech in general - something we'd definitely like to see.

Ultimately, it's down to you whether you want to give neurostimulating tech a try. We've given it a shot with the Halo Sport 2 and the Muse 2 wearables and we have survived to tell the tale, but there's definitely still a lot more exploration to be done as neuroscience and wearables come together in perfect union.

How we test

Michael Sawh


Michael Sawh has been covering the wearable tech industry since the very first Fitbit landed back in 2011. Previously the resident wearable tech expert at Trusted Reviews, he also marshaled the features section of T3.com.

He also regularly contributed to T3 magazine when they needed someone to talk about fitness trackers, running watches, headphones, tablets, and phones.

Michael writes for GQ, Wired, Coach Mag, Metro, MSN, BBC Focus, Stuff, TechRadar and has made several appearances on the BBC Travel Show to talk all things tech. 

Michael is a lover of all things sports and fitness-tech related, clocking up over 15 marathons and has put in serious hours in the pool all in the name of testing every fitness wearable going. Expect to see him with a minimum of two wearables at any given time.
