In 2018, professor Yuste was awarded the Tällberg/Eliasson Foundation prize due to his commitment to exploring the ethical implications of using emerging AI in the field of neurotechnology. This prize, which is "awarded annually to outstanding leaders who demonstrate the willingness and capacity to address the complexity of 21st-century challenges in innovative, risk-taking, and ethical ways, and whose work is global in aspiration or implication and is rooted in universal values" is a substantial honor.
