Brain structural basis of individual variability in dream recall frequency.
Brain Imaging and Behavior October 1, 2019 Shuqin Zhou, Jing Xu, Zihui Su et al.
People who more frequently recall their dreams have less cortical volume in the medial portion of the right fusiform gyrus and parahippocampal gyrus, as well as lower fractional anisotropy in the white matter fibers connected to those regions. These relationships were not affected by regular sleep. The findings provide direct evidence that brain structure is linked to individual differences in dream recall frequency.
