The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

RÉSUMÉ

Effects of Lentinus edodes (Berk.) Sing. extract on the spike activity of 28 pyramidal neurons from the CA1 region of the albino rat hippocampus were studied. In 12 (43%) neurons the extract application resulted in inhibition; in 4 (14%) neurons an insignificant increase in the spike discharge frequency was observed; and 12 (43%) cells showed no response. Latency and duration were as follows: for inhibitory responses (71 ± 14 s, 192 ± 26 s), for excitatory responses (63 ± 19 s, 116 ± 30 s). During washing, 11 neurons showed periodical group spike discharges that occurred on the average for 182 ± 35 s, but in one neuron they lasted for 34 minutes. It was suggested that in most cases the extract action caused a hyperpolarization of neuron membranes that during washing was replaced by a depolarization that was associated with the emergence of group discharges. An antagonist of GABA receptors, bicuculline, and an antagonist of 5-HT2/5-HT1C serotonin receptors, ritanserin, blocked an inhibitory effect of the extract partially or completely. This indicates that GABA or its agonist and substances that may activate serotonin receptors are involved in inhibition of neuron spike responses during the extract application.
