Overexcitability is a term introduced to current psychology by Kazimierz Dąbrowski as part of his theory of positive disintegration (TPD). Overexcitability is a rough translation of the Polish word 'nadpobudliwość', which is more accurately translated as 'superstimulatability' in English.
Entering into disintegration and subsequent higher processes of development occurs through developmental potential, including over-excitability and hypersensitivity. Unlike other theories of development such as Erikson's stages of psychosocial development , it is not assumed that even a majority of people progress through all levels.
Cell excitability is the change in membrane potential that is necessary for cellular responses in various tissues. The resting potential forms the basis of cell excitability and these processes are fundamental for the generation of graded and action potentials. Normal and pathological activities in the heart and brain can be modelled as ...
[1] In these theories working as the starting point, excitation-transfer theory is able to make assumptions regarding how the transition of one emotion to another cognitively occurs. [ 4 ] One of the assumptions states that excitation responses are, for the most part, ambiguous and are differentiated only by what emotions the brain assigns to ...
They often follow a membrane hyperpolarization, which can be the result of decreased excitability or increased inhibition. LTS result in the neuron reaching the threshold for an action potential . LTS is a large depolarization due to an increase in Ca 2+ conductance, so LTS is mediated by calcium (Ca 2+ ) conductance.
Hyperphantasia is the condition of having extremely vivid mental imagery. [1] It is the opposite condition to aphantasia, where mental visual imagery is not present. [2] [3] The experience of hyperphantasia is more common than aphantasia [4] [5] and has been described as being "as vivid as real seeing". [4]

Fig. 1 – Rheobase and chronaxie are points defined on the strength-duration curve for stimulus of an excitable tissue. Rheobase is a measure of membrane potential excitability . In neuroscience , rheobase is the minimal current amplitude of infinite duration that results in the depolarization threshold of the cell membranes being reached ...
