Compared with living free, the parasitic way of life has many attractions. Parasites create
problems for all animals. Potential hosts can respond by learning to live with parasites …

Chemosensory neurons translate perception of external chemical cues, including odorants,
tastants, and pheromones, into information that drives attraction or avoidance motor …

The ability to inherit learned information from parents could be evolutionarily beneficial,
enabling progeny to better survive dangerous conditions. We discovered that, after C …

While isolated motor actions can be correlated with activities of neuronal networks, an
unresolved problem is how the brain assembles these activities into organized behaviors …

There is no agreement on whether any invertebrates are conscious and no agreement on a
methodology that could settle the issue. How can the debate move forward? I distinguish …

Discrimination between pathogenic and beneficial microbes is essential for host organism
immunity and homeostasis. Here, we show that chemosensory detection of two secondary …

Variability is a prominent feature of behavior and is an active element of certain behavioral
strategies. To understand how neuronal circuits control variability, we examined the …

Sensory cues that predict reward or punishment are fundamental drivers of animal behavior.
For example, attractive odors of palatable food or a potential mate predict reward, while …

The same odorant can induce attractive or repulsive responses depending on its
concentration in various animals including humans. However, little is understood about the …

Memories formed early in life are particularly stable and influential, representing privileged
experiences that shape enduring behaviors. We show that exposing newly hatched C …
