IV. Delineating the maternal odor influence over visual categorizations in the developing brain Study 1: Maternal odor shapes rapid face categorization in the infant brain
Abstract
1. Introduction
2. Materials and Methods
Participants
Visual stimuli
Odor stimuli
Procedure
EEG recording and analysis
3. Results
Rapid face categorization in the infant brain
Maternal odor shapes the neural signature of face categorization
Common visual processes elicited by all images are immune to maternal odor influence
4. Discussion
