Male but not female olfaction is crucial for intermolt mating in European lobsters (Homarus gammarus L.).

abstract：:Nasal inhalation is the basis of olfactory perception and drives neural activity in olfactory and limbic brain regions. Therefore, our ability to investigate the neural underpinnings of olfaction and respiration can only be as good as our ability to characterize features of respiratory behavior. However, recordings of...
