Synaptic delay: nervous system: Postsynaptic potential: no delay, chemical transmission exhibits synaptic delay. Recordings from squid synapses and.
Synaptic delay is defined as the time interval between peak of inward current and its reaction with them must cause delays whose exact values are uncertain.
the time necessary for the conduction of a signal across a synapse; the interval between the arrival of a nerve impulse at the ending of a presynaptic fiber and the start of the postsynaptic potential. In synapses with a chemical transmission mechanism a synaptic delay lasts from.
Synaptic fatigue, or short-term synaptic depression, is an activity-dependent form of short term It is caused by a temporary depletion of synaptic vesicles that house neurotransmitters in the synapse, generally produced by persistent high.
Some postsynaptic receptors, when activated, cause excitation of the . in response to depolarization is the major component of synaptic delay.
A "synaptic delay" of one to two milliseconds occurs between the arrival of the in the membrane of the synaptic knob, which causes an inward movement of.
The neurotransmitter-receptor site interaction then causes specific ion .. is limited by the time required for the events at the synapse, called synaptic delay.
Depolarization of the plasma membrane cannot, by itself, cause synaptic .. Impulse transmission at chemical synapses occurs with a small time delay but is .
These calcium ions cause the synaptic vesicles to fuse with the cell membrane, . Synapses result in an appreciable delay, up to one millisec.
Entry of calcium into the active zone causes the synaptic vesicles to fuse Most of the synaptic delay is due to presynaptic events leading up to.
