Role of the brain and accessory olfactory system in the block to pregnancy in mice

Lloyd-Thomas, A., Keverne, E.B.·1982·Neuroscience

Abstract

Selective lesions have been made to the receptors in the main and accessory olfactory systems. In the absence of the accessory receptors, female mice are not able to show a neuroendocrine response to male pheromones but are able to detect male odours which induce the response. In the absence of main olfactory receptors, such discrimination of male odours is not possible, but the neuroendocrine response resulting in a block to pregnancy is maintained. These experiments suggest that cognitive aspects of olfaction are not essential for pregnancy block to occur and that in mice the dual olfactory systems are functional as well as anatomically distinct. Moreover, strain recognition can occur at the level of the accessory olfactory system without the female being able to display a behavioural awareness of this 'recognition'.

  • The suggestion that vomeronasal input might be unconscious comes in part from observations of vomeronasal system connections in the rodent brain.

    “The suggestion that vomeronasal input might be unconscious (Lloyd-Thomas and Keverne, 1982) comes in part from observations of vomeronasal system connections in the rodent brain.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
