Gradient Theories of Brain Activation: a Novel Application to Studying the Parental Brain

Parental brain research primarily employs general linear model–based (GLM-based) analyses to assess blood oxygenation level–dependent responses to infant auditory and visual cues, reporting common responses in shared cortical and subcortical structures. However, this approach does not reveal intermixed neural substrates related to different sensory modalities. We consider this notion in studying the parental brain. Spatial independent component...
