Basic Response Properties in Layer 4 C 21

چکیده
A model of LGN input to layer 4C of macaque primary visual cortex has been used to test the hypothesis that feedforward convergence of P and M inputs onto layer 4C spiny stellate neurons is suucient to explain the observed gradual change in receptive eld size and contrast sensitivity with depth in the layer. Overlap of dendrites of postsynaptic neurons between M and P input zones proved suucient to explain change in the lower two-thirds of layer 4C, while more rapid change in upper 4C was matched by proposing two diierent M inputs with partial overlap in upper 4C.

Neuronal response properties of somatosensory cortex (layer IV) are modulated following experience dependent plasticity in c-fiber depleted rats
Previous studies have shown that the receptive field properties, spontaneous activity and spatio-temporal interactions of low-threshold mechanical somatosensory cells in the barrel cortex are influenced by C-fibers. In this study, we examined the effect of C-fiber depletion on response properties of barrel cortex neurons following experience dependent plasticity. Methods: In this study, exte...
متن کاملEffect of sensory deprivation and Locus Coeruleus (LC) electrical stimulation on the response properties of layer IV barrel cortex neurons in male rats
Introduction: Barrel cortex of rodents is responsible for sensory information processing from muzzle whiskers. Locus coeruleus (LC) as the main source of norepinephrine (NE) in the cortex, is effective on the sensory information processing. Methods: Rats were divided to 2 groups. One group underwent sensory deprivation (P4) and the other group served as control and did not undergo sensory d...
متن کاملImproving Gas Sensing Properties of Tin Oxide Nanowires Palladium-Coated Using a Low Cost Technique
Thin films of SnO2 nanowires were successfully prepared by using chemical vapor deposition (CVD) process on quartz substrates. Afterwards, a thin layer of palladium (Pd) as a catalyst was coated on top of nanowires. For the deposition of Pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors...
متن کاملModulatory Effects of Memantine on Neuronal Response Properties in Rat Barrel Cortex
Introduction: Memantine as N-Methyl-D-aspartic acid (NMDA) receptor antagonist is used in some neurological disorders. It has been reported that memantine has modulatory effects on the somatosensory information processing in healthy subjects. This study investigated the effect of memantine on electrophysiological properties of barrel cortex neurons in male rats. Methods: Single unit recording ...
متن کاملA Study of ZnO Buffer Layer Effect on Physical Properties of ITO Thin Films Deposited on Different Substrates
The improvement of the physical properties of Indium Tin Oxide (ITO) layers is quite advantageous in photovoltaic applications. In this study the ITO film is deposited by RF sputtering onto p-type crystalline silicon (c-Si) with (100) orientation, multicrystalline silicon (mc-Si), and glass substrates coated with ZnO and annealed in vacuum furnace at 400°C. Electrical, optical, structural a...
