Background neuronal activity in thenucleus supraopticus and its modifications under the influence of parathyroid hormone

Modulation of neuronal impulse activity of the anterior hypothalamus as a functional basis of the mechanisms underlying hypothalamic control

“…Traditionally, already the initial visual analysis of the records of activity generated by individual neurons belonging to structures of this complex allows one to identify (i) cells generating successions of single APs, (ii) neurons whose discharges are grouped in some manner (including those with burst discharges), and (iii) neurons generating an activity of the mixed type [4,5,16,17,21,[25][26][27][28]. Some authors, when recording the BIA generated by hypothalamic neurons, classified such types of impulsation as bursting/grouped, single spike-arrhythmic, and permanently arrhythmic [21].…”

“…Usually, distributions of ISI of the neuronal activity (their densities of probabilities) are described as characteristics of the functional state of the given neuron [16,26, and autocorrelograms of ISI, which reflect the level of regularity of the current neuronal IA, are calculated [25,27]. For hypothalamic neurons, such a phenomenon as selection of the BIA frequencies under conditions of chronic visceral influenceв has been described [29].…”
