Exploring the effect of chronotype on hippocampal volume and shape: A combined approach.

abstract：:We ask if epidemiological studies into shift work and cancer may be prone to chronobiological errors. We illustrate how ignoring internal time (IT), or chronotype, may lead to what we call IT errors. Errors from truncating relevant external time (ET) information (activities start before and do not end with the shift) ...
