Excitatory postsynaptic potential

Model descriptions SWAN model The SWAN model [12,18] is based on the spectral action balance equation rather than the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. [13]: ∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity. The first term in the…

CHAPTER 2 2.1 ELECTROCARDIOGRAM The ECG Signal is a graphical representation of the electromechanical activity of system. The various propagation action potentials within the heart produce a current flow, which generates an electrical field that can be detected, in significantly attenuated form, at the body surface, via a differential voltage measurement system. The resulting measurement, when taken with electrodes in standardized locations, is known as the electrocardiogram. The ECG signal is…

II. 2. Hydraulic Jump 2.2.1. purpose 1. to create/generate hydraulic jump 2. To clarify questions about the fluid flow. 3. To determine the slatrility and characteristics of hydraulic jump, performed in the laboratory using impulse momentum and energy equations are specific. 4. to compare between the depth of flow measurements and the results of the theory. 2.2.2. Basic Theory A hydraulic jump occurs when the flow of the flow at a high speed exposure at a low-speed flow that occurs at the…

As I was making my Ecomap I came to realize that my priorities are not completely met and that I might need to change my routine in order to feel satisfied with the goals I want to accomplish in life. As I look at my elements I see that I am focusing my energy mainly in school, which is acceptable since this will help me fulfill my goals of having a successful career one day. School is a positive energy and it brings me satisfaction when I finish a term with a good grade, but at the same time it…

It was anticipated that the smaller blades will produce the most power because the shorter it is, the lighter the mass of the blade will be, therefore it will be easier for the wind to manipulate its movement. Wind Turbines are constructed to be proportionally large because it’s expected to capacitate above the Earth’s surface, where the wind is predicted to be more powerful. Since the blades in the experiment were all at the same level, and the air was pretty much controlled, the large rotors…

The features of action potentials are: threshold, all or none, is regenerative, saltatory conduction and refractory period. The threshold is generated when the membrane of the cell is depolarize around -50mv to evoke the action to occur. Action potential is all or none because is either no action potential or a full amplitude of action potential. We say that action potential is regenerative since a new action potential is generated at each location along the cell membrane. The saltatory…

1. The resting membrane potential is the potential difference across the cell membrane of excitable cells such as nerve and muscle cells. The 3 major factors that establish a resting membrane potential are as follows: (1) Non-diffusible anions: The resting membrane potential is influenced by the presence of large non-diffusible anions (proteins, nucleic acids and organic phosphates) inside a cell. The presence of large non-diffusible anions inside a cell attracts a large number of cations and…

actually stimulate them and consequently because of this these are known as antagonists, this therefore has the effect that it reduces stimulation of dopamine particularly in D2 receptors; doing this reduces the amount of dopamine transmitted to the postsynaptic neuron decreasing and by doing this it therefore stops the brain receiving this excess of dopamine delaying the effects which is thought to cause schizophrenia when there is an excess eliminating the symptoms (Wiley & Sons,…

Energy can be potential or kinetic. Radiant energy is a form of Kinetic energy. Movement of atoms, molecules, objects, waves, substances referring to a Kinetic energy. There are many different forms of kinetic energies like sound, motion, thermal energy, electrical energy. Nevertheless, there would be no life on Earth without radiant energy. What is radiant energy? The energy of electromagnetic waves and gravitational radiation is radiant energy. Radiant energy is the result of a change in…

Aim Simple Pendulum Experiment The aim of the experiment was to determine the effects of two factors (the length of a pendulum and the hanging mass of a pendulum) on the period of oscillation of the simple pendulum and to determine the value of g, the acceleration due to gravity. Apparatus Retort stand String Meter ruler Table Standard hex nuts (as suspended mass) Stopwatch Labelled Diagram Illustrating setup Method Experiment A: The simple pendulum was assembled using a retort stand,…
