Abstract

BACKGROUND: Nicotine exposure affects the hippocampus through activation of hippocampal nicotinic acetylcholine receptors (nAChRs), which are present throughout excitatory and inhibitory hippocampal circuitry. The role of cholinergic functioning in the hippocampus varies across developmental stages so that nicotine exposure differentially affects this region depending upon timing of exposure, producing developmentally distinct changes in structure, function, and behavior. METHODS: We synthesize findings across literature in this area to comprehensively review current understanding of the unique effects of nicotine exposure on the hippocampus throughout the lifespan with a focus on hippocampal morphology, cholinergic functioning, and hippocampusdependent learning and memory. CONCLUSIONS: Chronic and acute nicotine exposure differentially affect hippocampus structure, functioning, and related learning and memory in the perinatal period, adolescence, and aging. Age-related differences in sensitivity to nicotine exposure should be considered in the research of nicotine addiction and the development of nicotine addiction treatments.

  • The hippocampus, a crucial region for memory and learning, is heavily impacted by the neurotoxic effects of nicotine, resulting in persistent molecular changes and impairments.

    “The hippocampus, a crucial region for memory and learning, is heavily impacted by the neurotoxic effects of nicotine, resulting in persistent molecular changes and impairments [73].”

    From Nicotine on the developing brain. (2023) · cites this paper as [73]

    The ‘Hippocampal morphology’ and ‘Hippocampal plasticity and associated learning and memory’ sections (pages unavailable) describe lasting changes to learning-and-memory mechanisms and persistent impairments after prenatal or adolescent nicotine exposure. The claim omits that age-of-exposure qualification: the paper says adult-exposure deficits can be transient and discusses possible cognitive benefits in some aging populations. (LLM, conf=0.87)

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.
