The activity of spiking neurons is frequently described by renewal point process models. However, the assumption of independent intervals must be questioned for many different types of neurons. We review experimental studies that reported the feature of a negative serial correlation of neighboring intervals, commonly observed in neurons in the sensory periphery as well as in central neurons, notably in the mammalian cortex. In our experiments we observed the same short-lived negative serial dependence of intervals in the spontaneous activity of mushroom body extrinsic neurons in the honeybee. To model serial interval correlations of arbitrary lags, we suggest a family of autoregressive point processes. Its marginal interval distribution is described by the generalized gamma model, which includes as special cases the log-normal and gamma distributions, which have been widely used to characterize regular spiking neurons. In numeric simulations we investigated how serial correlation affects the variance of the neural spike count. We show that the experimentally confi rmed negative correlation reduces single-neuron variability, as quantifi ed by the Fano factor, by up to 50%, which favors the transmission of a rate code. We argue that the feature of a negative serial correlation is likely to be common to the class of spike-frequencyadapting neurons and that it might have been largely overlooked in extracellular single-unit recordings due to spike sorting errors.

The analysis was conducted on the wood of two 100−year−old oak species that grew in the riparian forest conditions. The aim of the study was to determine the effect of tree species on conventional wood densi− ty, compressive strength along the grain with a moisture content of 12% and above 30% and desorption strengthening. It was found that wood of both oak species differed in density, compressive strength along the grain and desorption strengthening. These differences should be taken into account in the processing and use of timber harvested in the prescribed cuts.

The study is an attempt to determine share of sapwood and heartwood in stems of European larch trees from II and III class of age, grown in conditions of fresh coniferous mixed forest site (BMśw), fresh forest mixed site (LMśw), fresh forest site (Lśw). The highest hare of heartwood was observed in stems of European larch in conditions of fresh forest site Lśw, and the smallest in conditions of fresh coniferous mixed forest site (BMśw). Differences were also observed within the investigated classes of age, and higher share of heartwood observed in III class of age. The smallest share of heartwood characterized codominant trees and the highest dominant trees (from main tree stand in Kraft classification).
