Brain implants are devices designed to interact with the brain through electrical, chemical, or optical signals. These implants are placed in specific areas of the nervous system with the aim of recording, stimulating, or modulating neuronal activity. One of the most recognized applications of brain implants is in the treatment of neurological diseases like Parkinson's disease, epilepsy, and treatment-resistant depression, using techniques such as deep brain stimulation to help regulate disrupted neural circuits.

In the future, these devices may enable more advanced interfaces between the brain and computers, opening new possibilities in communication, personalized medicine, and improved quality of life. Recent research encourages the use of increasingly smaller devices with enhanced capabilities that improve the connection between the brain and computers, which could lead to innovative applications in various fields, including healthcare and technology.

The development of these tiny implants that can send secret messages to the brain represents a significant step towards integrating biological systems with technological enhancements. As research continues, the implications of such technology could transform not just medical treatment but also the way we interact with machines and communicate with one another, potentially reshaping the landscape of human-computer interaction.
