Neuroplastic changes are defined as any enduring changes in the organisation of the central nervous system such as the strength of connections, representational patterns, or neuronal properties, either morphological or functional. At present we study how to induce and control plasticity in the human nervous system, and to derive new therapeutic strategies from this research.

Present research focuses on transcranial magnetic stimulation (TMS) (5) and transcranial direct current stimulation (TDCS) (3). TMS induces a short electric current in the human brain. It may be used to measure excitability changes (5) in the motor cortex or alterations in visual perception thresholds (4). It may also induce plastic changes of excitability when used repetitively (rTMS). At present a multicenter blinded rTMS protocol is applied in epilepsy patients. TDCS offers the prospect of inducing LTD and LTP like effects in the human brain when applied at least with a stimulation duration of 3 minutes(3). At present we investigate underlying mechanisms both in human and animal experiments. TDCS induced changes in motor cortex excitability may be detected by functional MR imaging (1). Other functional imaging studies trace the epileptic focus in epileptic patients in space and time(2). We extended our research field to dopaminergic, and, in future to GABA-ergic stem cells for the prospect of treating patients with Parkinson´s disease and epilepsy.
