Vividness of mental imagery reflects a broad range of internally generated visual experiences

The paper investigates vividness of mental imagery as a measure of subjective visual experiences and finds it correlates with various internal visual phenomena and can replace lengthy questionnaires.

Hemodynamic modelling improves population receptive field estimates

This paper shows that fitting the hemodynamic response function concurrently with population receptive field models improves accuracy and reveals variability in HRFs that can affect pRF estimates.

Spatial frequency adaptation modulates population receptive field sizes

The paper investigates how spatial frequency adaptation affects population receptive field sizes in the visual cortex using fMRI and psychophysical methods, finding that adaptation to low/high SF reduces/increases pRF sizes.

Size Aftereffect is non-local

The paper investigates size aftereffect, showing that size adaptation affects not only the adapter location but also distant parts of visual space, indicating widespread distortion of perceived size.
