The energy efficiency of neural signal transmission is important not only as a limiting factor in brain architecture, but it also influences the interpretation of functional brain imaging signals. Action potential generation in mammalian, versus invertebrate, axons is remarkably energy efficient. Here we demonstrate that this increase in energy efficiency is due largely to a warmer body tempera...

Neural circuit s are strongly affected by temperature and failure ensues at extreme s. However, detrimental effects of high temperature on neural pathways can be mitigated by prior exposure to high, but sub-lethal temperatures (heat shock). Using the migratory locust, Locusta migratoria, we investigated the effects of heat shock on the thermosensitivity of a visual interneuron (the descending c...

In this study we investigate metal spike formation of screen-printed Ag/Al pastes during contact firing in an infrared belt furnace and its influence on the characteristics of n-type bi-facial silicon solar cells. The boron emitters are formed in a co-diffusion step using boron doped PECVD layers. It is demonstrated that the formation of Ag/Al spikes results in strong FF and VOC losses limiting...

We investigate the phase locking of firing events in periodically forced stochastic excitable systems. Our study is motivated by the observation of randomly phase locked firing activity in a large number of neurons, especially those involved in transducing physical stimuli such as temperature, sound, pressure and electric fields. The purpose of our paper is to review our work on the biophysical...

The hippocampus plays an important role in short term memory, learning and spatial navigation. A characteristic feature of the hippocampal region is its expression of different electrical population rhythms and activities during different brain states. Physiological fluctuations in brain temperature affect the activity patterns in hippocampus, but the underlying cellular mechanisms are poorly u...

The theme of this article is to establish a basis for a physical model of optimization the kinetics of the process caustification (firing). In developing the mathematical model were used available data on the subject. The experimental part was carried out in order to find the optimal state of firing caustic magnesite at a given temperature and its reactivity to fast speed rotary kiln (FSRK) and...
