Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back

What Is Neurotransmitter? Neurotransmitter is a chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve‚ muscle‚ organ or other tissue. (Webster new world medicine dictionary. http://www.medterms.com/script/main/art.asp?articlekey=9973) What are Hormones? Hormones are chemicals that carry messages from organs of your body to your cells. The glands that secrete hormones are part of the endocrine system (pituitary‚ thyroid‚ adrenals

Which Model to Use for Cortical Spiking Neurons? Eugene M. Izhikevich Abstract—We discuss the biological plausibility and computational efficiency of some of the most useful models of spiking and bursting neurons. We compare their applicability to large-scale simulations of cortical neural networks. Index Terms—Chaos‚ Hodgkin–Huxley‚ pulse-coupled neural network (PCNN)‚ quadratic integrate-and-fire (I&F)‚ spike-timing. A. Tonic Spiking Most neurons are excitable‚ that is‚ they are quiescent

Overview Of Neuron Structural and Functional Properties and Electric Circuit Parameter Models from a Cellular Perspective. Neurons serve the purpose of receiving signals coming from neighbouring neurons; they assimilate these signals‚ and generate nerve pulses. They then conduct and transmit these nerve pulses to other neurons which are capable of receiving them. Neurons are the structural constituents of the brain. Typically‚ neurons are five to six orders of magnitude slower than silicon logic
