One consequence of the decreasing action potential duration is that the fidelity of the signal can be preserved in response to high frequency stimulation. Immature neurons are more prone to synaptic depression than potentiation after high frequency stimulation. [14]
Temporal summation occurs when a high frequency of action potentials in the presynaptic neuron elicits postsynaptic potentials that summate with each other. [7] The duration of a postsynaptic potential is longer than the interval between incoming action potentials.
Short-term effects: High frequency stimulation of a neuron for a short period of time increases the excitability of the neuron by lowering the amount of voltage required to fire an action potential. [3] High frequency stimulation leads to an increase in the intracellular concentration of sodium and calcium ions due to the repeated opening of ...
Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one.
Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. [5] A fused tetanic contraction is the strongest single-unit twitch in contraction. [6] When tetanized, the contracting tension in the muscle remains constant in a steady state. This is the maximal possible ...
In neurobiology, a tetanic stimulation consists of a high-frequency sequence of individual stimulations of a neuron. [citation needed] It is associated with potentiation. High-frequency stimulation causes an increase in release called post-tetanic potentiation (Kandel 2003). [citation needed] This presynaptic event is caused by calcium influx.
The signal is a short electrical pulse called action potential or 'spike'. Fig 2. Time course of neuronal action potential ("spike"). Note that the amplitude and the exact shape of the action potential can vary according to the exact experimental technique used for acquiring the signal.
The sweep technique is a hybrid frequency domain/time domain technique. [16] A plot of, for example, response amplitude versus the check size of a stimulus checkerboard pattern plot can be obtained in 10 seconds, far faster than when time-domain averaging is used to record an evoked potential for each of several check sizes.
