Binocular diplopia: See: Diplopia, binocular....
Binocular vision: The ability to maintain visual focus on
an object with both eyes, creating a single visual image. Lack of
binocular vision is normal in infants. Adults without binocular
vision experience distortions in depth perception and visual
measurement of distance....
Binocularity: The ability to focus upon an object with both eyes and create a single stereoscopic image. Binocularity requires highly convergent orbits.
The evolutionary increases among primates in the degree of orbital convergence have been noted to correlate with the expansion of visual brain str...
Binswanger disease: A form of dementia with blood vessel abnormalities in the deep white-matter of the brain causing loss of memory, decreasing cognition, and mood changes. Patients usually show signs of abnormal blood pressure (too high or too low), stroke, blood abnormalities, disease of the large...

Bioelectric impedance analysis
Bioelectric impedance analysis: A seemingly simple method for determining the lean body mass. Abbreviated BIA. There are two methods of the BIA. One involves standing on a special scale with footpads. A harmless amount of electrical current is sent through the body, and then the percentage of body f...
Biofeedback: A method of treatment that uses
monitors to feed back to patients physiological information of which they are normally unaware. By watching the monitor, patients can
learn by trial and error to adjust their thinking and
other mental processes in order to control "involuntary" bodily ...
