Konstantinos Meletis group
We are investigating the circuit mechanisms that shape motivated behaviours and the circuit imbalance that underlies core phenotypes of mood disorders.

A key to this investigation is the development and use of advanced technologies to probe the organization and function of candidate circuits, focusing on the basal ganglia, hypothalamus, habenula, and the serotonin system. The investigation of neurons and circuit is based on genetic access to neuron types in combination with technologies to record or manipulate neuronal activity with high temporal and spatial precision during behavioral tasks.
The Meletis laboratory has developed and applied a number of methods to map circuit organization and function, ranging from advanced molecular methods to determine gene expression patterns in cells and tissue – to in vivo approaches to define the role of neurons in aversion and motivation. Functional circuit mapping as well as molecular definitions of cell types and brain regions are central to establish a comprehensive understanding of how neurons and circuits generate motivated behaviors.
