Abstract:
Prolonged incubation with 25 microM homocysteine acid led to initial suppression of the synaptic transmission, which in 6 out of 12 cases was followed by the restoration of the population spike to values 63% from the control. In the rest of experiments, a transient decrease of the population spike amplitude was observed during wash-out of homocysteine acid. Such a pattern suggests that synaptic transmission has special mechanisms for adaptation to increasing concentrations of the excitatory amino acids which are potentially damaging.

Excitatory and Inhibitory Effects of Neurotransmitters
Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
