The effects of prenatal nicotine on radial-arm maze performance in rats

Sorenson, Charles A., Raskin, Lisa A., Suh, Yongsook·1991·Pharmacology Biochemistry and Behavior

Abstract

Studies have revealed lasting cognitive impairments, including deficits in attention and learning, in the offspring of women who smoke. Animal models have shown that prenatal nicotine can induce behavioral impairments, including deficits in learning and memory, and one study showed that only females were impaired on a maze task. The purpose of the present experiment was two-fold: 1) to attempt to replicate the reported sex difference in maze learning and 2) to assess the ability of nicotine-treated subjects to learn a maze that placed particularly heavy demands on their attentional capabilities. Pregnant mothers were given 6.0 mg/kg/day of nicotine in their drinking water. Offspring of both sexes were tested following weaning in an 8-arm-radial maze using a confinement procedure. Results showed that prenatal nicotine treatment produced significant impairments in performance in the radial-arm maze. These impairments were seen in animals of both sexes, a finding which challenges the view that only females prenatally treated with nicotine show deficits in maze learning.

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.
