Insects serve as a model for human brain function.
Food odors and social odors influence the same basic neurophysiological mechanism (i.e., the GnRH pulse), which allows them to alter the gene-cell-tissue-organ-organ system pathway which links them to hormones and behavior.
There is no scientific support for statements about brain size and complexity that challenge the known importance either of food odors or of social odors to mammalian behavior.
Dr. Richard L. Doty markets smell tests and smell testing equipment at smelltest.com. He is not familiar with the accurate conceptualization of mammalian pheromones.
There is only one animal model for food choice and for mate choice.
