RIKEN Center for Brain Science Laboratory for Glia-Neuron Circuit Dynamics
Team Leader: Jun Nagai (Ph.D.)
The lab’s mission is to discover fundamental mechanisms how the brain functions and malfunctions at molecular, cellular, circuit and behavioral levels by including “the other half” of the CNS; glial cells. Studies about astrocytes, a type of glia that tile the entire brain and structurally and functionally interact with neurons, synapses and other glia, have lagged behind partially due to the lack of tools. By developing and utilizing opto-/pharmaco-genetic, imaging, molecular biology and electrophysiology tools, the team aims to unveil astrocyte contributions to adaptive and maladaptive animal behaviors for delivering insights on future therapeutics.
