During the firing process, gun barrel bears thermal and chemical erosion of high-temperature gunpowder gas wear rotation band. The forced cone tended to most severely worn part barrel, which directly affects life barrel. Combined with test steel materials, this research studied forcing a medium caliber naval With commercial finite element software ABAQUS as platform, we took advanced adaptive m...
Whole-cell voltage recordings were made in vivo from excitatory neurons (n = 23) in layer 4 of the barrel cortex in urethane-anaesthetised rats. Their receptive fields (RFs) for a brief whisker deflection were mapped, the position of the cell soma relative to barrel borders was determined for 15 cells and dendritic and axonal arbors were reconstructed for all cells. Three classes of neurons wer...
Introduction: Barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. Vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. On the other hand, Norepinephrine (NE) and locus coeruleus, which is the main source of NE, influenced response properties of cortical bar...
