abstract = {Real-time investigations of neurotransmitter release
provide a direct insight on the mechanisms involved in
synaptic communication. Carbon fiber microelectrodes are
state-of-the-art tools for electrochemical measurements of
single vesicle neurotransmitter release. Yet, they lack
high-throughput capabilities that are required for
collecting robust statistically significant data across
multiple samples. Here, we present a chip-based recording
system enabling parallel in vitro measurements of individual
neurotransmitter release events from cells, cultured
directly on planar multielectrode arrays. The applicability
of this cell-based platform to pharmacological screening is
demonstrated by resolving minute concentration-dependent
effects of the dopamine reuptake inhibitor nomifensine on
recorded single-vesicle release events from PC12 cells. The
experimental results, showing an increased half-time of the
recorded events, are complemented by an analytical model for
the verification of drug action.},
