This study identifies distinct hippocampal cellular pathologies associated with cognition in schizophrenia and affective psychoses, showing differences in metabolite biomarkers between these conditions.

The paper compares cellular biomarkers in psychiatric diagnoses using 3D hippocampal MR spectroscopy, finding both similarities and differences in symptom-related pathologies across affective and non-affective psychoses.

The paper introduces an integrated Ising model with global inhibition to explain decision-making, showing it can improve accuracy and has unique learning properties.

The paper shows that GABA in the dACC affects appetitive and aversive learning through distinct mechanisms involving different brain regions and connectivity patterns.

This study compares 1D and 2D linear-combination modeling of MRS data, finding similar accuracy and uncertainty estimation between the two approaches, with 2D showing stability under correlated noise.

The paper shows that brief motor memory reactivation leads to increased cortical inhibition and overnight learning gains, similar to repetitive practice, suggesting different neural mechanisms underlie these processes.

This study shows early changes in glutamate and GABA in the motor cortex after motor learning support memory consolidation and plasticity over time.

This study investigates inhibitory and excitatory mechanisms in the human dorsal anterior cingulate cortex during reinforcement learning and finds that GABA levels correlate with learning performance.
