The brain-computer interface (BCI) technology domain is constantly progressing as researchers and companies collaborate to devise inventive solutions that connect the human brain with external devices. This expanding sector, driven by the need for better communication, rehabilitation, and augmented cognitive capabilities, has given rise to both invasive and non-invasive BCI techniques. In this article, we will delve into the current status of brain-computer interface technology, explore the distinctions between invasive and non-invasive BCIs, and consider the potential consequences for the future development of this rapidly changing field.


Invasive BCI: Pioneering New Frontiers

Invasive brain-computer interfaces necessitate the surgical insertion of electrodes into the brain, offering the possibility of capturing high-resolution neural signals. This approach allows for more accurate communication between the brain and external devices. 

Pioneering companies such as Neuralink and Blackrock Microsystems are leading this advancement by concentrating on the development of implantable devices for a variety of applications, including neuroprosthetics and the treatment of neurological disorders.

Despite the potential benefits, invasive BCI technology faces challenges, such as the risk of infection and the complexity of surgical implantation. Furthermore, the long-term stability and biocompatibility of these devices remain crucial concerns that researchers must address before widespread adoption.


Non-Invasive BCI: Unlocking New Possibilities

In contrast, non-invasive brain-computer interfaces do not require direct contact with the brain, utilizing external sensors to detect neural signals. Electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) are two popular non-invasive techniques used by companies like Emotiv, Neurable, and Kernel.

Non-invasive BCIs offer several advantages over their invasive counterparts, including lower risk, ease of use, and reduced cost. However, the primary drawback is the lower signal resolution, which can result in less accurate communication between the brain and the interface.

Companies at the forefront of BCI technology:


Pioneering invasive BCI technology, Neuralink is developing a high-bandwidth, implantable device called the "Link." The company aims to facilitate direct communication between the human brain and computers, with initial applications targeting the treatment of neurological disorders, such as epilepsy and Parkinson's disease.


Kernel's non-invasive BCI technology, called "Kernel Flow," employs functional near-infrared spectroscopy (fNIRS) to monitor brain activity. The company focuses on advancing neuroscience and exploring applications in mental health, neurodegenerative disorders, and cognitive enhancement.


Specializing in non-invasive, EEG-based BCI technology, Neurable aims to improve human-computer interaction in virtual reality (VR) and augmented reality (AR) environments. Their platform enables users to control digital interfaces using brain activity, providing more intuitive and immersive experiences.


With a focus on non-invasive BCI technology, BrainCo develops wearable devices like the "Focus1" headband. These devices analyze brain activity to enhance focus and attention, with applications in education, fitness, and rehabilitation.


Emotiv offers non-invasive, EEG-based BCIs that measure brain activity to enable users to control devices and applications through their thoughts. Their product lineup includes the "EPOC X" and "Insight" headsets, used in various fields such as research, gaming, and accessibility.


Supporting both invasive and non-invasive BCI research, OpenBCI offers open-source hardware and software platforms. Their modular products, including the "Ultracortex" headset and "Cyton" board, empower researchers and developers to innovate and collaborate in the BCI domain.


By leveraging BCI technology, MindMaze creates immersive VR experiences for neurorehabilitation. Their non-invasive platform, "MindMotion," aids in the recovery of stroke and traumatic brain injury patients, using brain activity and motion tracking to facilitate motor and cognitive rehabilitation.

CTRL-labs (acquired by Facebook)

CTRL-labs developed a non-invasive BCI technology called "neural input," which interprets electrical signals from arm muscles to enable users to control devices through thought alone. This approach, while not directly measuring brain activity, offers a novel way to interact with technology without invasive procedures.

Blackrock Neurotech

Specializing in invasive BCI technology, Blackrock Neurotech designs high-performance neural recording and stimulation systems. Their products, such as the "Utah Array" and "Cereplex" family of devices, cater to both research and clinical applications in neuroscience and neuroprosthetics.

g.tec medical engineering

g.tec provides various BCI solutions, including both invasive and non-invasive technologies, for research, rehabilitation, and communication. They integrate their technology into medical devices and applications, offering products like the "g.Nautilus" and "g.HIamp" for EEG-based brain-computer interfacing.


Balancing Advantages and Challenges

As both invasive and non-invasive brain-computer interface technology continue to evolve, researchers and companies must weigh the benefits and drawbacks of each approach. Invasive BCIs may offer superior signal resolution, but their inherent risks and complex surgical procedures present significant barriers to entry. On the other hand, non-invasive BCIs provide a safer, more accessible alternative, albeit with reduced signal quality.

The progression of brain-computer interface technology will likely encompass a blend of invasive and non-invasive strategies, adapted to cater to distinct applications and individual requirements. The continuous advancement of cutting-edge materials, signal processing techniques, and artificial intelligence will likely propel additional breakthroughs in this area, altering how we engage with our digital surroundings and possibly bringing about transformative solutions for neurological disorders.
