| brown-sequard syndrome | <syndrome> A syndrome due to damage of one half of the spinal cord, resulting in ipsilateral paralysis below the level of the lesion and loss of discriminatory and joint sensation, and contralateral loss of pain and temperature sensation. Brown-sequard was a french physiologist, 1817-1894. The syndrome is also called brown-sequard disease and brown-sequard paralysis but this latter should not be confused with a flaccid paralysis seen in disorders of the urinary tract called by the same name. (12 Dec 1998) |
| Brown-Sequard's paralysis | <neurology, syndrome> A type of spinal cord lesion that is characterised by hemiparaplegia and hyperesthesia, but with loss of motor function on the same side as the lesion and hemianaesthesia on the opposite side. (27 Sep 1997) |

| Brownian motion | <chemistry, physics> Random motion of small objects as a result of intermolecular collisions. First described by the 19th Century microscopist, Brown. (18 Nov 1997) |
| brownian movement | Erratic, nondirectional, zigzag movement observed by ultramicroscope in certain colloidal solutions and by microscope in suspensions of light particulate matter that results from the jostling or bumping of the larger particles by the molecules in the suspending medium which are regarded as being in continuous motion.
