Cortical Implants in Cerebrum - A Review

Abstract

The cortical implant is neuroprosthetic which is a direct bridging link to the cerebral cortex of the brain. It provides stimulation and has different benefits depending upon the type of design and the placement of the implant. It is a typical cortical with a microelectrode array, a small device that transmits or receives the neural signal. Its main goal is to replace the neural circuitry in the brain that no longer functions properly. It has a wide variety of potential uses from restoring vision to helping patients who suffer from dementia. These implants are placed on the prefrontal cortex. Prefrontal Cortex is helpful in restoring the attention that helps in decision making. These implants act as a replacement that replaces the damaged tissues in the cortex. This review was done based on the articles obtained from various platforms like PubMed, PubMed Central and Google Scholar. They were collected with a restriction on a time basis from 2000 - 2020. The inclusion criteria were original research papers. In vitro, studied among various conditions and articles that contain pros and cons. Exclusion criteria came into account for review articles, retracted articles and articles of other languages. All the articles are selected based on cortical implants in the cerebrum. Cortical implants are placed to replace the neural circuitry in the brain that no longer functions properly. It helps patients with neurological disorders. It helps patients who have difficulty in complex sensory and neural functions. The biggest advantage of neuroprosthesis is that it is directly interfaced with the cortex.
