The present experiments were conducted to determine the electrophysiological and
pharmacological properties of substantia nigra neurons in the mouse. These cells were …

We have discovered a neuronal system that releases neurotransmitter via exocytosis from
the cell body. In the large dopamine cell of the pond snail Planorbis corneus, depolarization …

A relation between neuromelanin synthesis and vulnerability of dopaminergic neurons is
suggested by the fact that heavily pigmented cells are preferentially lost in aging and …

Differential depletion of neurotransmitter by amphetamine in two classes of vesicles, termed
large vesicles and small vesicles, has been studied with amperometry. Carbon fiber …

The heterogeneous nature of vesicles has been studied by evaluating exocytotic events
released from the cell body of a dopamine-containing neuron of Planorbis corneus …

An electrochemical model to calculate the relative size and neurotransmitter concentration of
individual nerve cell vesicles is presented to examine potentially different types of vesicles in …

The methods used for measurements of fluorescence intensity in histochemical preparation
will be described. Under certain conditions, the FIF intensity of biological objects shows a …

We have discovered a neuronal system that fires bursting exocytotic events. In the giant
dopamine neuron of the fresh water snail Planorbis corneus, bursting exocytotic events are …

The response of central dopamine (DA) systems to physical stress (10 s footshock, 0.5 mA,
to naive rats) or psychological stress (10 s stay in experimental chamber 1 day after …

Peptide actions were investigated in an in vitro preparation of the cns of the snail Planorbis
corneus, especially with respect to possible effects on the transmission between a …
