Using serial tachograms to measure the evoked impulseactivity of isolated hippocampal neurons

Abstract: Використання серійних тахограм для дослідження викликаної імпульсної активності ізольованих нейронів гіпокампа При тривалому відведенні мембранного потенціалу від ізольованих нейронів гіпокампа, досліджувалися зміни їх генераційної активності у часі. Описано використання тахограм для оцінки електричної активності та запропоновано використання серійних тахограм, аналіз яких дає змогу підвищити достовірність результатів. Виділено три фази зміни імпульсної активності ізольованого нейрона в процесі експериментальн… Show more

“…At the same time, under the condition of Aβ1–42 withdrawal, we observed impairment in the vitality of neurons with a decrease in the threshold of inhibition of generation and a general decrease in the rhythmicity of the pulse. Arrhythmia of AP generation can be a marker of irreversible degradation of neurons’ impulse activity and is always observed before the loss of the neuronal ability to fire, according to our previous experiments ( Iavors’kyi and Luk”ianets’, 2013 ). The study suggests that the high concentrations of Aβ1-42 can partially reverse its effect on neurons.…”

“…The neuronal firing activity was studied based on the frequencies of firing rate, the ability to generate APs at low and high amplitudes of the testing current, and the rhythmicity of firing, as was described previously ( Yavorskii et al, 2006 ; Yavorsky and Lukyanetz, 2009 , 2015 ; Iavors’kyi and Luk”ianets’, 2013 ). APs firing of isolated hippocampal CA1 neurons were obtained in the “ramp” protocol, the records from the fast-spiking neuron shown on Figure 1A .…”
