The spike trains of inhibited pacemaker neurons seen through the magnifying glass of nonlinear analyses

Segundo, J.P. ; Sugihara, George ; Dixon, Paul ; Stiber, M. ; Bersier, Louis-Félix

In: Neuroscience, 1998, vol. 87, no. 4, p. 741-766

This communication describes the new information that may be obtained by applying nonlinear analytical techniques to neurobiological time-series. Specifically, we consider the sequence of interspike intervals Ti (the «timing») of trains recorded from synaptically inhibited crayfish pacemaker neurons. As reported earlier, different postsynaptic spike train forms (sets of...

Reactions and energy absorption of trees subject to rockfall: a detailed assessment using a new experimental method

Lundström, Tor ; Jonsson, Martin J. ; Volkwein, Axel ; Stoffel, Markus

In: Tree Physiology, 2009/29//doi:10.1093/treephys/tpn030

A new method for investigating the detailed reaction and the energy absorption of trees during a rock impact was developed and applied to 15 subalpine Norway spruce (Picea abies L. Karst) trees. A wedge-shaped trolley, guided by prestressed steel wires, was mounted on a forested slope to simulate a falling rock. The trolley accelerates down the wires and hits a tree at a preselected stem height...
