Intracranial electrophysiology reveals distinct neural representations of nociception and salience in the human brain

The paper uses intracranial recordings to show that nociception and salience have distinct neural representations in the human brain, with different anatomical, temporal, and functional characteristics.

Diffusion MRI Tractography Predicts Electrophysiological Connectivity and Explains Spectral Signatures of Evoked Potentials in the Human Brain

The paper uses diffusion MRI and SEEG to predict electrophysiological connectivity and explain evoked potential spectral signatures in the human brain.

Distinct yet neighboring neural populations encode past, future, and surrounding speech context in the human temporal lobe

The paper shows that distinct neural populations in the human temporal lobe encode speech context from past, future, and surrounding input, with implications for speech comprehension models.
