Jonas Group

Cellular Neuroscience

Synapses enable communication between neurons in the brain. The Jonas group investigates how signals pass through these vital interfaces – a major undertaking in the field of neuroscience.

Understanding the function of the brain is a major challenge in the 21st century. The human brain comprises ~100 billion neurons, which communicate through ~10000 synapses per cell. Excitatory synapses use glutamate as a transmitter, whereas inhibitory synapses release Gamma-Aminobutyric acid (GABA). The group addresses two major questions. First, what are the biophysical signaling and plasticity mechanisms at glutamatergic and GABAergic synapses in the cortex? Second, how do specific synaptic properties generate higher network functions? In their work, the group combines nanophysiology, presynaptic patch-clamp and multi-cell recording, two-photon Ca2+ imaging, optogenetics, functional anatomy (“flash and freeze” electron microscopy), in vivo recording, and modeling. One focus is hippocampal mossy fiber synapses and output synapses of parvalbumin-expressing GABAergic interneurons
