...Katarina Pankova; Alexander Borst ABSTRACT The identification of neurotransmitter type used by a neuron is important for the functional dissection of neuronal circuits. In the model organism Drosophila melanogaster , several methods for discerning the neurotransmitter systems are available. Here...

This complex feeding mode switch is regulated by the neurotransmitter serotonin in a previously uncharacterised role, a process that appears conserved across several...

... infected rodents have high levels of dopamine and that the parasite encodes a tyrosine hydroxylase, the rate-limiting enzyme in the synthesis of this neurotransmitter. A mechanism is proposed that could explain the behaviour changes due to parasite regulation of dopamine. This could have important...

... and processes in the heart were examined using immunocytochemical techniques. All 15 neurons of the cardiac ganglion showed glutamate-like immunoreactivity. Glutamate may be a neurotransmitter of the cardiac ganglion neurons. JSTX also blocked cardiac acceleration by activation of CA1 and CA2 axons. CA1 and CA2...
