Overexcitability is a rough translation of the Polish word 'nadpobudliwość', which is more accurately translated as 'superstimulatability' in English. “The prefix over attached to ‘excitability’ serves to indicate that the reactions of excitation are over and above average in intensity, duration and frequency."
The strength-duration time constant (chronaxie) and rheobase are parameters that describe the strength-duration curve—the curve that relates the intensity of a threshold stimulus to its duration. As the duration of a test stimulus increases, the strength of the current required to activate a single fiber action potential decreases.

Irritability is the excitatory ability that living organisms have to respond to changes in their environment. The term is used for both the physiological reaction to stimuli and for the pathological, abnormal or excessive sensitivity to stimuli.
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 ...
Dolf Zillmann began developing excitation-transfer theory in the late 1960s through the early 1970s and continued to refine it into the 21st century. [1] The theory itself is based largely on Clark Hull's notion of residual excitation (i.e., drive theory), Stanley Schachter's two factor theory of emotion, and the application of the three-factor theory of emotions.
The test is designed to describe the neonate's response to the environment after being born. [2] This approach was innovative for recognizing that a baby is a highly developed organism , even when just newly born.
Tourette syndrome or Tourette's syndrome (abbreviated as TS or Tourette's) is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic.
