A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. They are often conceptualized as a human–machine interface that skips the intermediary of moving body parts (hands...), although they also raise the possibility of erasing the distinction between brain and machine. BCI implementations range from non-invasive and partially invasive to invasive, based on how physically close electrodes are to brain tissue.
Neurotechnology encompasses any method or electronic device which interfaces with the nervous system to monitor or modulate neural activity.
Miguel Ângelo Laporta Nicolelis, is a Brazilian scientist, physician and Duke School of Medicine Professor in Neuroscience at Duke University, best known for his pioneering work surrounding brain-computer interface technology.
Brain implants, often referred to as neural implants, are technological devices that connect directly to a biological subject's brain – usually placed on the surface of the brain, or attached to the brain's cortex. A common purpose of modern brain implants and the focus of much current research is establishing a biomedical prosthesis circumventing areas in the brain that have become dysfunctional after a stroke or other head injuries. This includes sensory substitution, e.g., in vision. Other brain implants are used in animal experiments simply to record brain activity for scientific reasons. Some brain implants involve creating interfaces between neural systems and computer chips. This work is part of a wider research field called brain–computer interfaces.
Neuroplasticity, also known as neural plasticity or just plasticity, is the ability of neural networks in the brain to change through growth and reorganization. Neuroplasticity refers to the brain's ability to reorganize and rewire its neural connections, enabling it to adapt and function in ways that differ from its prior state. This process can occur in response to learning new skills, experiencing environmental changes, recovering from injuries, or adapting to sensory or cognitive deficits. Such adaptability highlights the dynamic and ever-evolving nature of the brain, even into adulthood. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping or neural oscillation. Other forms of neuroplasticity include homologous area adaptation, cross modal reassignment, map expansion, and compensatory masquerade. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, information acquisition, environmental influences, pregnancy, caloric intake, practice/training, and psychological stress.
Neuroprosthetics is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses. They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality.
Edward Vaughan Evarts was an American neuroscientist. He pioneered single-unit recordings from the brains of awake, behaving monkeys.
Neuroinformatics is the emergent field that combines informatics and neuroscience. Neuroinformatics is related with neuroscience data and information processing by artificial neural networks. There are three main directions where neuroinformatics has to be applied:
In neuroscience, single-unit recordings provide a method of measuring the electro-physiological responses of a single neuron using a microelectrode system. When a neuron generates an action potential, the signal propagates down the neuron as a current which flows in and out of the cell through excitable membrane regions in the soma and axon. A microelectrode is inserted into the brain, where it can record the rate of change in voltage with respect to time. These microelectrodes must be fine-tipped, impedance matching; they are primarily glass micro-pipettes, metal microelectrodes made of platinum, tungsten, iridium or even iridium oxide. Microelectrodes can be carefully placed close to the cell membrane, allowing the ability to record extracellularly.
Tipu Zahed Aziz was a Bangladeshi-born British professor of neurosurgery at the John Radcliffe Hospital in Oxford, Aarhus Denmark and Porto, Portugal. He specialised in the study and treatment of Parkinson's disease, multiple sclerosis, dystonia, spasmodic torticollis, fixed abnormal posture of the neck, tremor, and intractable neuropathic pain. Besides his medical work, he was also notable as a public commentator in support of animal experimentation.
Michael Matthias Merzenich is an American neuroscientist and professor emeritus at the University of California, San Francisco. He took the sensory cortex maps developed by his predecessors and refined them using dense micro-electrode mapping techniques. Using this, he definitively showed there to be multiple somatotopic maps of the body in the postcentral sulcus, and multiple tonotopic maps of the acoustic inputs in the superior temporal plane.
Neuroscience Research Australia is an independent, not for profit medical research institute based in Sydney, Australia. The institute is made up of over 400 researchers specialising in research to improve the lives of people living with brain and nervous system disorders. The institute’s research spans neurodegeneration, including dementia and Parkinson’s disease; mental health and mental illness including bipolar disorder and schizophrenia; and translational neuroscience including falls prevention, pain and injury prevention.
Neurostimulation is the purposeful modulation of the nervous system's activity using invasive or non-invasive means. Neurostimulation usually refers to the electromagnetic approaches to neuromodulation.
Dick Frans Swaab is a Dutch physician and neurobiologist. He is a professor of neurobiology at the University of Amsterdam and was until 2005 Director of the Netherlands Institute for Brain Research of the Royal Netherlands Academy of Arts and Sciences.
Sophie Kerttu Scott is a British neuroscientist and Wellcome Trust Senior Fellow at University College London (UCL). Her research investigates the cognitive neuroscience of voices, speech and laughter particularly speech perception, speech production, vocal emotions and human communication. She also serves as director of UCL's Institute of Cognitive Neuroscience.
Stentrode is a small stent-mounted electrode array permanently implanted into a blood vessel in the brain, without the need for open brain surgery. It is in clinical trials as a brain–computer interface (BCI) for people with paralyzed or missing limbs, who will use their neural signals or thoughts to control external devices, which currently include computer operating systems. The device may ultimately be used to control powered exoskeletons, robotic prosthesis, computers or other devices.
A chronic electrode implant is an electronic device implanted chronically into the brain or other electrically excitable tissue. It may record electrical impulses in the brain or may stimulate neurons with electrical impulses from an external source.
Neuralink Corp. is an American neurotechnology company that has developed, as of 2024, implantable brain–computer interfaces (BCIs). It was founded by Elon Musk and a team of eight scientists and engineers. Neuralink was launched in 2016 and was first publicly reported in March 2017.
Peter Hagoort is a Dutch neuroscientist who studies the neurobiology of language.
