Transcranial Focused Ultrasound for Identifying the Neural Substrate of Conscious Perception.

Neuroscience and biobehavioral reviews November 19, 2025 Daniel K Freeman, Brian Odegaard, Seung-Schik Yoo et al.

Transcranial focused ultrasound (tFUS) can stimulate the human brain non-invasively with millimeter-scale precision, targeting both cortical and deep structures. This new tool offers a potential breakthrough for studying the neural correlates of conscious perception, overcoming the coarse spatial resolution and limited depth of traditional electrical or magnetic stimulation. Because tFUS requires extensive preparation and regulatory approvals, careful experimental planning is essential. The authors provide a roadmap for using tFUS in humans to explore the neural substrate of conscious perception.

Transcranial Focused Ultrasound for Identifying the Neural Substrate of Conscious Perception

arXiv Preprint Archive July 11, 2025 Daniel K. Freeman, Brian Odegaard, Seung-Schik Yoo et al.

Transcranial focused ultrasound (tFUS) can stimulate the human brain non-invasively through the skull with millimeter-scale spatial resolution, targeting both cortical and deep brain structures. This emerging tool offers a promising method for investigating the neural basis of conscious perception, overcoming the coarse spatial resolution of traditional electrical or magnetic stimulation. The authors provide a roadmap for using tFUS in humans to explore the neural substrate of conscious perception, emphasizing the need for careful experimental planning due to extensive preparation and regulatory approvals.

Should a Few Null Findings Falsify Prefrontal Theories of Conscious Perception?

The Journal of neuroscience : the official journal of the Society for Neuroscience October 4, 2017 Brian Odegaard, Robert T Knight, Hakwan Lau

Activity in the prefrontal cortex (PFC) is critical for conscious perception, contradicting claims that PFC lesions do not affect subjective experience, that PFC activity does not reflect perceptual content, or that its role is solely due to task-related reporting. Empirical evidence shows PFC is essential for subjective experience in perception, not just for performing visual tasks. Confusing these two aspects can lead to misunderstandings.
