| frequency of occurrence | The number of times a given event occurs at specified sample points during a defined period. (07 Apr 1998) |
| frequency spectrum | The range of frequencies in a signal, used to describe the resolving power of an imaging system in radiology. (05 Mar 2000) |
| frequency, urinary | Urinating too often, at too frequent intervals, not due to an unusually large volume of urine, but rather to a decrease in the capacity of the bladder to hold urine. (12 Dec 1998) |
| fundamental frequency | The principal component of a sound wave, which has the greatest wavelength, tone produced by the vibration of the vocal folds before the air reaches any cavities. (05 Mar 2000) |
| low frequency transduction | Specialised transduction in which only a small portion of the prophage particles, because of their defectiveness, are able to develop sufficiently to serve as effective transducing agents. (05 Mar 2000) |
| after-nystagmus | Nystagmus occurring after the abrupt cessation of rotation in the opposite direction of the rotatory nystagmus. (05 Mar 2000) |
| amaurotic nystagmus | The pendular or, rarely, jerky nystagmus seen in severely reduced vision. Synonym: amaurotic nystagmus. (05 Mar 2000) |
| Bruns' nystagmus | A fine, jerking (vestibular) nystagmus on horizontal gaze in one direction, together with a slower, larger amplitude (gaze, paretic) nystagmus on looking in the opposite direction; due to lateral brainstem compression, usually by a cerebellar-pontine angle mass such as an acoustic neuroma. (05 Mar 2000) |
| caloric nystagmus | Jerky nystagmus induced by labyrinthine stimulation with warm or cold water injected into the ear canal. (27 Sep 1997) |
| galvanic nystagmus | Nystagmus involving galvanic stimulation of the labyrinth. (05 Mar 2000) |

| gaze paretic nystagmus | A nystagmus occurring in partial gaze paralysis when an attempt is made to look in the direction of the gaze paresis. (05 Mar 2000) |
| vertical nystagmus | An up-and-down oscillation of the eyes. (05 Mar 2000) |
