Medical term:

suspenopsia


suppression

 [sŭ-presh´un]
the act of holding back or checking.
1. the stopping or inhibition of something, such as a secretion, excretion, normal discharge, or other function.
2. in psychiatry, conscious inhibition of an unacceptable impulse or idea as contrasted with repression, which is unconscious.
3. in genetics, a second mutation occurring at a site different from the first mutation site and able to mask or suppress the phenotypic expression of the first mutation; the organism appears to be reverted but is in fact doubly mutant.
4. inhibition of the erythrocytic stage of Plasmodium to prevent clinical attacks of malaria; used for prophylaxis.
5. cortical inhibition of perception of objects in all or part of the visual field of one eye during binocular vision.
bone marrow suppression reduction of the cell-forming functions of bone marrow, such as by a drug or because of replacement of the marrow by a disease process. Called also myelophthisis and myelosuppression.
labor suppression in the nursing interventions classification, a nursing intervention defined as controlling uterine contractions prior to 37 weeks of gestation to prevent preterm birth. See also labor.
lactation suppression in the nursing interventions classification, a nursing intervention defined as facilitating the cessation of lactation and minimizing breast engorgement after childbirth.
overdrive suppression the suppression of intrinsic cellular automaticity by a rapid outside stimulus. In cardiology this refers to the inhibitory effect of a faster pacemaker on a slower pacemaker. The faster rate causes an accumulation of intracellular sodium, stimulating the sodium-potassium pump, which hyperpolarizes the cell so that it takes longer to reach threshold potential. This phenomenon is present in healthy His-Purkinje cells but decreases with a decrease in membrane potential and loss of fast sodium channels.

sup·pres·sion

(sŭ-presh'ŭn),
1. Deliberately excluding from conscious thought.
See also: epistasis. Compare: repression.
2. Arrest of the secretion of a fluid, such as urine or bile.
See also: epistasis. Compare: retention (2).
3. Checking of an abnormal flow or discharge, as in suppression of a hemorrhage.
See also: epistasis.
4. The effect of a second mutation that overwrites a phenotypic change caused by a previous mutation at a different point on the chromosome.
See also: epistasis.
5. Inhibition of vision in one eye when dissimilar images fall on corresponding retinal points.
6. The attenuation or arrest of an immune response.

suppression

  1. failure to develop any organ or structure.
  2. (genetics) the mechanism whereby the effects of a primary MUTATION are suppressed or negated by a second mutation, the SUPPRESSOR MUTATION, that occurs at a different site from that of the primary mutation. Thus a function lost by a primary mutation can be totally or partially restored by a suppressor mutation. Suppression may be intergenic, where the suppressor mutation occurs in a different GENE from that of the primary mutation, or intragenic, where the suppressor mutation occurs at a different site in the same gene.

suppression 

The process by which the brain inhibits the retinal image (or part of it) of one eye, when both eyes are simultaneously stimulated. This occurs to avoid diplopia as in strabismus, in uncorrected anisometropia, in retinal rivalry, etc. Syn. suspenopsia (this term actually refers to voluntary suppression as occurs, for example, when using a monocular microscope with one eye); suspension (most often used when referring to partial suppression). See cheiroscope; physiological diplopia; Javal's grid; Mallett fixation disparity unit; Remy separator; retinal rivalry; Bagolini lens test; four prism dioptre base out test; FRIEND test; Turville infinity balance test; Worth's four dot test; vectogram.
