We study two firing properties to characterize the activities of a neuron: frequency-current (f-I) curves and phase response curves (PRCs), with variation in the intrinsic temperature scaling parameter (μ) controlling the opening and closing of ionic channels. We show a peak of the firing frequency for small μ in a class I neuron with the I value immediately after the saddle-node bifurcation, w...

Circadian pacemakers drive many daily molecular, physiological and behavioural rhythms. We investigated whether the main olfactory bulb is a functional circadian pacemaker in rats. Long-term, multielectrode recordings revealed that individual, cultured bulb neurons expressed near 24-h oscillations in firing rate. Real-time recordings of Period1 gene activity showed that a population of cells wi...

introduction: although formalin-induced activity in primary afferent fibers and spinal dorsal ‎horn is well described, the midbrain neural basis underlying each phase of behavior in ‎formalin test has not been clarified. the present study was designed to investigate the nucleus ‎cuneiformis (cnf)‎‏ ‏neuronal responses during two phases after subcutaneous injection of ‎formalin into the hind paw...

Temperature control is an important parameter in the fields of engineering and medical Laboratory. Culturing micro bacteria enzymes for purpose diagnoses or process development manufacturing industries require their optimum temperature to be monitored control. In this research work Fuzzy logic controller was designed incubator Temperature, by computing appropriate firing angle. MATLAB Simulink ...

An integrated solar combined cycle (ISCC) is analyzed at "off-design" operating conditions. Using the principles of thermodynamics heat and mass transfer a computer code is developed in FORTRAN programming language to simulate the system’s hourly performance under steady state conditions. Three scenarios are considered for the study. In the first one, only the combined cycle (CC) is studied. In...
