Lab Research Areas

Communication is an essential part of our daily lives. Our ability to communicate shapes our interactions with our environment and with members of our social groups. Despite this, we know little about how multisensory natural signals integrate in the brain to inform moment-by-moment social decisions. How are sensory signals integrated over time during a social encounter? How is social communication influenced by environmental context, internal motivation, and previous experience?

The Deutsch Lab’s research is focused on identifying neural mechanisms for the processing and production of socially meaningful communication at the level of circuits, cells, and molecules.

Scholar Profile

At his lab in the Sagol Department of Neurobiology at the University of Haifa, David Deutsch is studying the neural basis of social communication, using Drosophila melanogaster (the fruit fly) as a model system. Leveraging his postdoctoral work, Dr. Deutsch will use brain imaging, behavioral quantification, neural tracing and computational modeling to identify neural mechanisms and principles for the processing and production of socially meaningful communication.

Dr. Deutsch conducted his doctoral research in the Neurobiology Department at the Weizmann Institute. In his PhD he used the rat whisker system as a model for studying the principles that underly what is known as active sensing. Humans move their eyes to explore their surroundings; rats use their whiskers to collect relevant information about the location and identity of objects in their vicinity. Using fine behavioral quantification, Dr. Deutsch revealed a new mode of active sensing that allows rats to extract relevant information about a novel object.

In his postdoc at the Princeton Neuroscience Institute, Dr. Deutsch studied the neural basis of acoustic communication. While extending his expertise in using computational tools for behavioral quantification, he also implemented brain imaging (using a two-photon microscope) and neural circuit analysis to reveal how brain circuits are linked to social behaviors. In one study, he revealed a group of cells that are tuned to a specific aspect of the fly courtship song. While these cells respond similarly in both sexes, activating them drives different behaviors in males and females. In a separate study, he found the neural basis of a motivational state in the fly brain. Activating a small group of sexually dimorphic cells in the female brain drives minutes-long persistent activity in the female brain, while also strongly modulating her mating behaviors.

Building on these studies, Dr. Deutsch’s lab will attempt to determine how internal factors (such as prior experience or motivational state) and incoming multisensory environmental cues (such as the courtship song) are integrated in the fly’s nervous system, allowing it to adapt its decisions and adjust to fluctuating goals and needs.
