Research

The brain is the most complex organ in the human body. Rough estimates suggest that the central nervous system of higher mammals is comprised of 1011 neurons. These neurons communicate with each other by 1015 contact sites termed synapses. At present, our knowledge about synaptic function is largely based on the highly detailed analysis of a small number of “model synapses”, such as the neuromuscular junction and the calyx of Held. However, the function of cortical synapses is just beginning to emerge.
The group of Prof. Peter Jonas focuses on the hippocampus, which plays a key role in spatial information processing and episodic memory. The hippocampus is comprised of three subfields, the dentate gyrus, the CA3 (cornu ammonis 3) region, and the CA1 (cornu ammonis 1) region. Two general types of neurons are present in all regions: principal neurons, which use glutamate as transmitter and have an excitatory effect on their postsynaptic target cells, and interneurons, which release g-aminobutyric acid (GABA) and have inhibitory postsynaptic effects. Both types of cells exist in various subtypes, such as granule cells, pyramidal neurons, and various types of GABAergic interneurons. Understanding the rules of signal processing in such complex networks requires information about both connectivity (the “connectom”) and function of identified synapses.
The central goal of his research team is to determine the rules of communication at identified synapses in hippocampal microcircuits at a quantitative level. This may ultimately allow him to understand how higher brain functions are implemented in brain circuits and how these functions are perturbed in neurological and psychiatric diseases.
