This study shows that NMDA receptor loss in the medial prefrontal cortex impairs value updating and reward history integration in mice, mimicking schizophrenia-like cognitive deficits.

This paper presents high-resolution diffusion MRI techniques for in vivo and ex vivo macaque brain imaging at 10.5 Tesla, enabling detailed connectivity studies.

This study identifies a functional dissociation in human posterior cingulate cortex, showing dorsal PCC integrates value and memory-based decisions while ventral PCC does not.

The paper analyzes electrophysiological signals from white matter and finds they have distinct spectral features and higher complexity compared to gray matter.

This paper develops a scalable PS-OCT system for whole-brain imaging in rhesus macaques, achieving high-resolution volumetric data with multi-terabyte datasets.

The paper shows that structural connectivity in the human visual cortex preserves retinotopic organization, revealing a retinotopic wiring principle and systematic perceptual asymmetries in early visual cortex connectivity.

The paper examines the preservation of anterior limb of the internal capsule (ALIC) topography in treatment-resistant psychiatric patients, finding it consistent with healthy and preclinical patterns.

This paper evaluates the diffusion-weighted steady-state free precession (DW-SSFP) sequence for ex vivo macaque brain imaging at 10.5T, showing improved SNR efficiency and geometric distortion reduction.

This paper introduces standardized tractography protocols for mapping cortico-subcortical tracts in human and macaque brains, showing robustness and applicability across species.

The paper maps semantic organization in the human hippocampus, finding semantotopic patterns and multiscale semantic similarity along the mediolateral axis.

This study tracks neural and behavioral changes in macaques during chronic cocaine use, recovery, and re-exposure, revealing convergent and divergent effects across subjects.

This study examines how 16p11.2 duplication affects reward learning in mice, finding male-biased impacts in early training but no genotype effect in a bandit task, while NMDAR antagonism impairs choice flexibility in all animals.

The paper shows that the intraparietal sulcus (IPS) is functionally connected to frontal and cingulate regions during action stopping, with different connectivity patterns during successful stopping and control failures.

This study shows that the human hippocampus can process oddball tones and language stimuli, including semantic and grammatical features, even under general anesthesia.

The paper compares microstructure and fiber orientation measurements from polarization-sensitive OCT and ultra-high-field dMRI in macaque brains and demonstrates a GAN for improving MRI resolution using OCT data.

The paper develops a biophysically constrained model to estimate 3D conductivity paths from SPES data, showing it correlates with PEP features and outperforms anatomical-based methods.

This study evaluates how anatomical details affect electric fields in transcranial stimulation simulations using a non-human primate model.

The paper investigates intrinsic timescales of neural processing across the whole rhesus macaque brain using fMRI and electrophysiology, finding consistency between timescales and hierarchical temporal dynamics.

This paper demonstrates ultra-high field (10.5 T) resting state fMRI in macaques, revealing detailed and robust resting state components similar to human connectomes.

The paper identifies two subregions of the orbitofrontal cortex (OFC) with distinct connectivity to the posterior cingulate cortex (PCC) and shows that the OFCin-PCC circuit relays choice signals from value to action space.

The paper examines hierarchical organization in medial prefrontal cortex regions during risky choices in macaques, finding increased decodability and longer timescales along a specific pathway.

The paper identifies a cortico-basal ganglia network that predicts information about uncertain rewards and motivates information seeking behavior in primates.
