DOI: 10.1002/dev.22178
Abstract: Resting-state electroencephalography (EEG) provides developmental neuroscientists a noninvasive view into the neural underpinnings of cognition and emotion. Recently, the psychometric properties of two widely used neural measures in early childhood-frontal alpha asymmetry and delta-beta coupling-have… read more here.

DOI: 10.1002/esp.70169
Abstract: Geomorphic processes are shaped by climate changes, tectonic movements and human activities. Investigating these interactions is crucial for understanding climate change and landform dynamics. However, the mechanisms driving landform development in high‐altitude regions such as… read more here.
