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.
(Brain–computer interface research also includes technology such as EEG arrays that allow interface between mind and machine but do not require direct implantation of a device.) Neural implants such as deep brain stimulation and vagus nerve stimulation are increasingly becoming routine for patients with Parkinson's disease and clinical ...
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.
The procedure to implant the device does not require a craniotomy, and the implantation is designed to be reversible. [4] Precision Neuroscience aims to treat neurological conditions such as spinal cord injury, stroke , and neurodegenerative diseases such as ALS and traumatic brain injury .
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]
Chang has made fundamental contributions to understanding the neural code of speech and neuropsychiatric conditions in the human brain. [5]Chang pioneered the use of high-density direct electrophysiological recordings from cortex, which enabled him and colleagues to determine the selective tuning of cortical neurons to specific acoustic and phonetic features in consonants and vowels.

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).
Ion implantation setup with mass separator. Ion implantation equipment typically consists of an ion source, where ions of the desired element are produced, an accelerator, where the ions are electrostatically accelerated to a high energy or using radiofrequency, and a target chamber, where the ions impinge on a target, which is the material to be implanted.
