Functional dynamics of de-afferented early visual cortex in glaucoma

This study uses fMRI to show that in glaucoma, de-afferented visual cortex responses in V1, V2, and V3 shift from negative to positive during task-related conditions, similar to macular degeneration and retinitis pigmentosa.

Reinstatement of cortical outcome representations during higher-order learning

This study identifies reinstatement of cortical outcome representations during second-order conditioning in humans using fMRI.

Increased hippocampal excitability and altered learning dynamics mediate cognitive mapping deficits in human aging

This study investigates age-related cognitive mapping deficits using behavioral and fMRI data, finding increased hippocampal excitability and altered learning dynamics in older adults.

Decisions bias future choices by modifying hippocampal associative memories

The paper shows that making a choice without outcomes modifies hippocampal memories and biases future decisions.

Information-based taste maps in insular cortex are shaped by stimulus concentration

The paper uses fMRI and multivariate pattern analysis to show that taste maps in human gustatory cortex change with stimulus concentration, revealing distinct spatial layouts for different taste categories at varying concentrations.

Evidence for allocentric boundary and goal direction information in the human entorhinal cortex and subiculum

This study uses fMRI and multivariate decoding to show allocentric boundary and goal direction coding in human entorhinal cortex and subiculum.

The anterior insula channels prefrontal expectancy signals during affective processing

This study investigates how the anterior insula modulates prefrontal cortex responses to emotional stimuli based on expectancy signals using fMRI and cross-correlation analyses.

Motion and physiological noise effects on amygdala real-time fMRI neurofeedback learning

This study investigates how motion and physiological noise affect amygdala real-time fMRI neurofeedback learning and finds that these factors do not drive self-regulation learning.

The effect of acquisition resolution on orientation decoding from V1: comparison of 3T and 7T

This study compares decoding performance of visual orientation from 3T and 7T fMRI data, finding that 3T decoding is impaired but can be improved with additional voxel selection at 3mm resolution.
