## OpenAI bets on ultrasound for brain control Merge Labs, a startup founded by Sam Altman, has announced that it has raised $252 million in funding. The company's goal is to **develop** a technology that uses ultrasound to read and write information directly into the human brain. OpenAI's investment in Merge Labs highlights the growing interest in the field of neural interfaces and their potential applications. The technology, still in its early stages, could open new frontiers in medicine, cognitive **improve**ment, and human-machine interaction. However, it also raises important ethical and security questions that need to be addressed carefully. Brain-computer interfaces (BCIs) are a rapidly expanding field, with several companies and research institutions engaged in **developing** innovative solutions. These technologies promise to revolutionize the treatment of neurological diseases, motor rehabilitation, and communication for people with disabilities. At the same time, it is essential to consider the ethical and social implications related to the access and use of such technologies.
