Beta and Gamma Dynamics in Attentional Networks Predict Conscious Reports.

The Journal of neuroscience : the official journal of the Society for Neuroscience May 27, 2026 Alfredo Spagna, Jianghao Liu, Paolo Bartolomeo

What neural events precede conscious reports? Hemisphere-asymmetric attentional networks are causally related to conscious perception (Kaufmann et al., 2024; Bartolomeo et al., 2025), but their spectrotemporal dynamics remain unclear. Here, we used magnetoencephalography to examine brain oscillations occurring in human participants (male and female) before a near-threshold target during the...

Visual mental imagery in typical imagers and in aphantasia: A millimeter-scale 7-T fMRI study.

Cortex; a journal devoted to the study of the nervous system and behavior April 2025 Jianghao Liu, Minye Zhan, Dounia Hajhajate et al.

Most of us effortlessly describe visual objects, whether seen or remembered. Yet, around 4% of people report congenital aphantasia: they struggle to visualize objects despite being able to describe their visual appearance. What neural mechanisms create this disparity between subjective experience and objective performance? Aphantasia can provide novel insights into conscious processing and...
