In neurons that are involved in chemical synaptic transmission, neurotransmitters are synthesized either in the neuronal cell body, or within the presynaptic terminal, depending on the type of neurotransmitter being synthesized and the location of enzymes involved in its synthesis.
The experiment is practised in schools around the world and is often used at open evenings to show the more engaging and entertaining aspects of science in secondary education settings. [2] [3] The experiment shows the amount of energy there is in a piece of candy. Jelly babies [4] or gummy bears [5] are often used for theatrics.
These experiments have furthermore opened new avenues for preventative drug efficacy. Measurement of chronaxie and rheobase in sural sensory fibers has revealed mild reductions in excitability in diabetics, as evidenced by significant reductions in conduction velocity and chronaxie of sensory fibers with corresponding increases in rheobase.

Cell excitability is a property that is induced during early embriogenesis. [27] Excitability of a cell has also been defined as the ease with which a response may be triggered. [28] The resting and threshold potentials forms the basis of cell excitability and these processes are fundamental for the generation of graded and action potentials.
From the point of view of control theory, the voltage clamp experiment can be described in terms of the application of a high-gain output feedback control law [13] to the neuronal membrane. [14] Mathematically, the membrane voltage can be modeled by a conductance-based model with an input given by the applied current I a p p ( t ...
Atoms can be excited by heat, electricity, or light. The hydrogen atom provides a simple example of this concept.. The ground state of the hydrogen atom has the atom's single electron in the lowest possible orbital (that is, the spherically symmetric "1s" wave function, which, so far, has been demonstrated to have the lowest possible quantum numbers).
The musical group The Glitch Mob used cymatics to produce the music video "Becoming Harmonious (ft. Metal Mother)". [ 13 ] Influenced by yantra diagrams and cymatics, artist and fashion designer Mandali Mendrilla created a sculpture dress called "Kamadhenu" (Wish Tree Dress III) the pattern of which is based on a Yantra diagram depicting ...
