Tegmental atrophy in isolated REM sleep behaviour disorder: Ex vivo-informed in vivo imaging

This study identifies tegmental atrophy in iRBD using VBM and a novel brainstem atlas, linking atrophy in specific nuclei to autonomic dysfunction.

All spectral frequencies of neural activity reveal semantic representation in the human anterior ventral temporal cortex

The paper decodes animacy from ECoG data in the human anterior ventral temporal cortex, finding that semantic information is encoded by local populations and interacts with distributed cortical regions.

State-dependent role of interhemispheric pathway for motor recovery in primates

This study shows that the interhemispheric pathway's role in motor recovery changes from inhibitory to facilitatory in primates after corticospinal tract lesioning, affecting hand movements during early recovery.

Representational similarity learning reveals a graded multi-dimensional semantic space in the human anterior temporal cortex

The paper uses representational similarity learning to decode a graded multidimensional semantic space in the human anterior temporal cortex from ECoG data.

Spinal cord extracts from sporadic ALS induce and propagate TDP-43 pathology in cerebral organoids

The paper shows that spinal cord extracts from sporadic ALS patients induce and spread TDP-43 pathology in human cerebral organoids, mimicking ALS pathophysiology.

Evidence for a deep, distributed and dynamic semantic code in human ventral anterior temporal cortex

This study shows semantic information in human ventral anterior temporal cortex is dynamically distributed with stable and changing elements, supporting a hub-like role in semantic networks.

Connectivity Gradient in the Human Left Inferior Frontal Gyrus: Intraoperative Cortico-Cortical Evoked Potential Study

This study uses intraoperative cortico-cortical evoked potentials to map connectivity gradients in the human left inferior frontal gyrus, revealing distinct connections between its subdivisions and temporal lobe regions.
