Neuropixels probes (or "Neuropixels") are electrodes developed in 2017 to record the activity of hundreds of neurons in the brain. The probes are based on CMOS technology and have 1,000 recording sites arranged in two rows on a thin, 1-cm long shank.
All three components are surgically implanted inside the body. Lead implantation may take place under local anesthesia or under general anesthesia ("asleep DBS"), such as for dystonia. A hole about 14 mm in diameter is drilled in the skull and the probe electrode is inserted stereotactically, using either frame-based or frameless stereotaxis. [14]
An auditory brainstem implant (ABI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf, due to retrocochlear hearing impairment (due to illness or injury damaging the cochlea or auditory nerve, and so precluding the use of a cochlear implant).
3D Sarfus image of a DNA biochip. The microarray—the dense, two-dimensional grid of biosensors—is the critical component of a biochip platform. Typically, the sensors are deposited on a flat substrate, which may either be passive (e.g. silicon or glass) or active, the latter consisting of integrated electronics or micromechanical devices that perform or assist signal transduction.
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments.
Silicon-based microelectrode arrays include two specific models: the Michigan and Utah arrays. Michigan arrays allow a higher density of sensors for implantation as well as a higher spatial resolution than microwire MEAs. They also allow signals to be obtained along the length of the shank, rather than just at the ends of the shanks.
Memory implantation techniques were developed in the 1990s as a way of providing evidence of how easy it is to distort people's memories of past events. Most of the studies on memory implantation were published in the context of the debate about repressed memories and the possible danger of digging for lost memories in therapy. The successful ...
In the United States, many states such as Wisconsin (as of 2006), North Dakota (2007), California (2007), Oklahoma (2008), and Georgia (2010) have laws making it illegal to force a person to have a microchip implanted, though politicians acknowledge they are unaware of cases of such forced implantation.
