Animal behavior is shaped by a variety of" internal states"—partially hidden variables that
profoundly shape perception, cognition, and action. The neural basis of internal states, such …

Among the many wonders of nature, the sense of smell of the fly Drosophila melanogaster
might seem, at first glance, of esoteric interest. Nevertheless, for over a century, the 'nose'of …

Brains contain networks of interconnected neurons and so knowing the network architecture
is essential for understanding brain function. We therefore mapped the synaptic-resolution …

Behavioral flexibility is critical to survival. Animals must adapt their behavioral responses
based on changes in the environmental context, internal state, or experience. Studies in …

Although recent studies indicate the impact of microbes on the central nervous systems and
behavior, it remains unclear how the relationship between the functionality of the nervous …

When deciding what to eat, animals evaluate sensory information about food quality
alongside multiple ongoing internal states,,,,,,,,–. How internal states interact to alter …

Feeding decisions are fundamental to survival, and decision making is often disrupted in
disease. Here, we show that neural activity in a small population of neurons projecting to the …

Using odors to find food and mates is one of the most ancient and highly conserved
behaviors. Arthropods from flies to moths to crabs use broadly similar strategies to navigate …

Highlights•Drosophila larva enables combining comprehensive synapse resolution
connectivity maps with cellular-resolution activity maps and behavior maps.•This approach …

Motivations bias our responses to stimuli, producing behavioural outcomes that match our
needs and goals. Here we describe a mechanism behind this phenomenon: adjusting the …
