Synapses have different functions: When it comes to the transmission of electrical impulses in neurons, one differentiates essentially two different types of synapses. Those which provide a transmission of an impulse, and those which are responsible for arrest. Excitatory postsynaptic potential (EPSP) The excitatory postsynaptic potential describes the electrically positive change in the membrane potential responsible for the triggering of the action potential.

What is solar thermal? Definition and Simple Explanation: Solar thermal means using solar energy to convert it to heat. This can be used for the treatment of hot water or for the heating of rooms. Depending on the location and the structural condition of the house, solar thermal energy can cover up to 65 percent of the demand for hot water per year.
