The word "postsynaptic" in example sentences

This region is known as the postsynaptic density (PSD). ❋ Unknown (2010)

Accumulation of the neurotransmitters in the synaptic cleft occurs provoking an increase in the stimulation of postsynaptic receptors. 3 ❋ Unknown (2010)

The postsynaptic receptors become supersensitive to neurotransmitter effects and may be related to an increase in the number of alpha and beta receptors. 4 This may occur in compensation for chronic cocaine use when norepinephrine becomes depleted. 4 ❋ Unknown (2010)

Direct-acting pressors have their action extracellularly at postsynaptic receptors. 4 The evaluation of liver function at initial presentation andfour tosix weeks following recovery is recommended, although the incidence of hepatotoxicity following acute overdose is rare. 5 Caution should be exercised in the use of sedative/hypnotics for CNS excitation because of synergistic depressant effects during overdose. ❋ Unknown (2010)

After the impulse has again been initiated, the neurotransmitter-complex must be inactivated otherwise impulses (above and beyond the original impulse) will continue and can exhaust the postsynaptic event causing muscle paralysis, for example. ❋ Unknown (2008)

Generally, neurotoxins affecting neurotransmission act to increase or decrease the release of a neurotransmitter at the presynaptic membrane, block receptors at the postsynaptic membrane, or modify the inactivation process of the neurotransmitter. ❋ Unknown (2008)

This starts the process of impulse/action potential generation in the postsynaptic neuron or receptor cell. ❋ Unknown (2008)

Strychnine inhibits the neurotransmitter glycine at postsynaptic sites resulting in an increased level of neuronal excitability in the CNS. ❋ Unknown (2008)

Higher doses of the drug block the postsynaptic dopamine receptors resulting in an improvement in psychoses. ❋ Unknown (2008)

The neurotransmitter diffuses across the synaptic junction and binds to receptors on the postsynaptic membrane. ❋ Unknown (2008)

Following binding of the neurotransmitter with a receptor, the postsynaptic membrane depolarizes which results in the generation of an impulse on the next neuron or the effector cell, e.g., muscle cell or secretory cell. ❋ Unknown (2008)

Despite the fact that the larva have no nervous system, they nonetheless possess approximately 70% of the genes required to make the complex structure of neural synapses known as the “postsynaptic density” (PSD). ❋ Unknown (2007)

At chemical synapses, there is a cleft between pre - and postsynaptic cell. ❋ Atmanspacher, Harald (2006)

Given that neurons 'activity depends partly upon their total input, and total input depends partly on synaptic weights (e.g., presynaptic neurotransmitter release rate, number and efficacy of postsynaptic receptors, availability of enzymes in synaptic cleft), the capacity of biological networks to change their synaptic weights make them plastic vector-to-vector transformers. ❋ Bickle, John (2006)

At electrical synapses, the current generated by the action potential at the presynaptic neuron flows directly into the postsynaptic cell, which is physically connected to the presynaptic terminal by a so-called gap junction. ❋ Atmanspacher, Harald (2006)

The transmitter diffuses across the synaptic cleft and binds to receptors at the postsynaptic membrane, thus opening an ion channel ❋ Atmanspacher, Harald (2006)

Four stages are described in detail: the synthesis and storage of neurotransmitters, neurotransmitter release, the role of postsynaptic receptors and the inactivation of neurotransmitters. ❋ Unknown (2005)

Additionally, there is "No data is available regarding effects of the drug on postsynaptic receptors." ❋ Unknown (2005)
