The Brain implants, also known as neural implants, are modern gadgets that are affixed to the cortex of the brain or implanted on the surface of the brain to link directly to a biological subject's brain. Establishing a biomedical prosthesis that avoids brain regions that have become dysfunctional as a result of a stroke or other head injuries is a common goal of contemporary brain implants and the subject of much current research. Some brain implants are utilized in animal investigations purely for the purpose of scientifically recording brain function. Creating interfaces between neural systems and computer chips is a part of several brain implants.

Electrical impulses from a single neuron or from a collection of neurons (biological neural networks) in the brain can be electrically stimulated, blocked, recorded, or both recorded and stimulated at the same time. The method of blocking is known as intra-abdominal vagal blocking, the application of brain implants had been severely constrained due to the complexity of neural processing and the lack of access to action potential-related signals utilizing neuroimaging techniques. In an effort to create goods that limit any bad impacts that an active implant can have on the brain and that the body can experience, a great deal of study is also being done on the surface chemistry of neural implants.

As part of the Reliable Neural-Interface Technology (RE-NET) programme, which was started by DARPA in 2010 to address the immediate need for high-performance neural interfaces to control the dexterous functions made possible by DARPA's advanced prosthetic limbs, brain implants are also being investigated. The objective is to give these limbs an easy-to-use, high-bandwidth control interface. Since 1997, neurostimulators have been used to treat the symptoms of conditions like depression, Parkinson's disease, dystonia, and epilepsy. An increasing number of people suffering from chronic neurologic and behavioural diseases are finding relief thanks to quick advances in neurostimulation technologies. Electrical stimulation is applied to drive brain function inside a circuit in neurostimulation therapies, which include both invasive and noninvasive methods.

Researchers are also investigating a variety of delivery methods, such as using veins, to administer these implants without brain surgery; by leaving the skull sealed shut, patients could receive their neural implants without running the risk of seizures, strokes, or long-term neural impairments, all of which can result from open-brain surgery. Many materials used in modern brain implants include tungsten, silicon, platinum-iridium, and even stainless steel. Future brain implants might be made of more unusual substances like polycarbonate urethane and nanoscale carbon fibres (nanotubes). But, in 2019, a startup by the name of Synchron was successful in implanting a brain-computer interface via the blood arteries. Nearly all implants require open brain surgery.

Who is a good candidate for receiving brain implants and what are good and negative applications of neural implants are two ethical issues that have been brought up. While deep brain stimulation is more common for Parkinson's disease patients, there could be some unintended behavioural consequences. Apathy, hallucinations, compulsive gambling, hypersexuality, cognitive impairment, and depression are all possible, according to reports in the literature. These, however, might only be short-lived and connected to the proper positioning and calibration of the stimulator, making them possibly reversible.

In 2015, it was revealed that researchers at the Southern Federal University in Rostov-on-Perception Don's and Recognition Neuro-technologies Laboratory had proposed implanting microchips in the brains of rats to help them detect explosive devices.A technology that would turn locusts into "Remote controlled explosive detectors" with electrodes in their brains transmitting information about hazardous compounds back to their operators was reportedly being developed by American engineers in 2016.

Researchers at the University of Melbourne, who established the business Synchron in 2016, released clinical data in 2020 regarding their development of Stentrode, a device that may be implanted via the jugular vein without requiring open brain surgery.
