Recordings from brainstem nuclei involved in chemosensory regulation of breathing in awake freely behaving mice show different complementary types of neuronal responses to hypercapnia in the retrotrapezoid nucleus and the rostral medullary raphe.

The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.

Vglut2-based glutamatergic signaling in central noradrenergic neurons is dispensable for baseline breathing and hypercapnic, hypoxic chemosensory reflexes, which challenges the current understanding of central noradrenergic neurons in breathing control.

Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.

Optogenetic stimulation of odor- and taste-sensing neurons of the fruit fly larva combined with reverse-correlation analysis has been used to build mathematical models that predict navigational behavior.

Olfactory neurons of insects, once thought to express only a single type of olfactory receptor, exhibit widespread co-expression of receptors from multiple chemosensory gene families.

Male pheromone environment increases the cholinergic synaptic transmission at the neuromuscular junction in Caenorhabditis elegans hermaphrodites during development, decreasing hermaphrodites' locomotion activity and promoting mating efficiency.

Neurotransmission pathways from primary to secondary neurons encode odor and underlie age-related sensory behavioral declines.

Active expiration in anesthetized rats is driven by the lateral parafacial region, but requires an additional form of excitation from another source.

Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.
