Example sentences for: tetanic
How can you use “tetanic” in a sentence? Here are some example sentences to help you improve your vocabulary:
The γ frequency oscillations (30-100 Hz) are characteristic of responses to sensory input measured by cortical EEG [ 9 ] . In the hippocampal slice preparation, γ oscillations can be evoked by brief, high frequency tetanic stimuli to region CA1 [ 10 11 12 13 ] . The extracellular field potential response during these oscillations takes the form of a train of population spikes in stratum pyramidal at γ and β (15-30 Hz) frequencies [ 14 ] . Intracellular recordings during γ oscillations induced by tetanic stimulation reveal a slow membrane depolarization in conjunction with GABA A receptor-mediated inhibitory postsynaptic potentials [ 11 15 ] . This synaptic inhibition-based γ activity entrains action potential generation in pyramidal neurons, leading to the population spikes at γ band frequencies.
Therefore, we investigated whether high-intensity tetanic stimulation could induce γ oscillations followed by SD.
These factors are likely to be more evident after the tetanic contraction (75 pulses per s) than after staircase (10 pulses per s).
Results from this and our previous study showed that the SD always followed hyperthermic bursts [ 8 ] , but tetanic stimulation induced only γ oscillations in the absence of SD (Fig.
In our previous report, the extracellular K +indeed elevated dramatically during hyperthermia-induced epileptiform-like population spikes and SDs [ 8 ] . Field effects further contribute to post-tetanic γ oscillations [ 25 26 ] . High Frequency tetanic stimuli leads to cellular swelling [ 27 28 ] , increasing extracellular resistance.
