Abstract

The majority of adolescents report to have smoked a cigarette at least once. Adolescence is a critical period of brain development during which maturation of areas involved in cognitive functioning, such as the medial prefrontal cortex (mPFC), is still ongoing. Tobacco smoking during this age may compromise the normal course of prefrontal development and lead to cognitive impairments in later life. In addition, adolescent smokers suffer from attention deficits, which progress with the years of smoking. Recent studies in rodents reveal the molecular changes induced by adolescent nicotine exposure that alter the functioning of synapses in the PFC and underlie the lasting effects on cognitive function. In particular, the expression and function of metabotropic glutamate receptors (mGluRs) are changed and this has an impact on short- and long-term plasticity of glutamatergic synapses in the PFC and ultimately on the attention performance. Here, we review and discuss these recent findings.

  • Exposure to nicotine in adolescence is associated with brain-wide changes to the expression of discrete nAChR subunits, with some transient changes appearing during treatment or withdrawal, but with some persistent changes enduring until adulthood.

    “Exposure to nicotine in adolescence is associated with brain-wide changes to the expression of discrete nAChR subunits, with some transient changes appearing during treatment or withdrawal, but with some persistent changes enduring until adulthood.”

    From Adolescent nicotine exposure and persistent neurocircuitry changes: unveiling lifelong psychiatric risks (2025) · cites this paper as [114]

    The ‘Upregulation of nAChR and synaptic mGluR expression’ section reports short-term increases in α4- and β2-containing nAChRs in adolescent rodent mPFC and mentions acute and longer-lasting changes in receptor binding in regions such as cortex and striatum. It does not establish brain-wide, subunit-specific expression changes persisting into adulthood. The ‘Lasting synaptic adaptations in the PFC’ section instead says PFC nAChR levels returned to baseline five weeks after exposure; the persistent change described there is in mGluR2.

  • The peripubertal period marks a time of unique vulnerability to the long-term effects of drug exposure in a variety of animal models.

    “While pubertal hormones affect propensity for drug self-administration, the peripubertal period also marks a time of unique vulnerability to the long-term effects of drug exposure in a variety of animal models.”

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.
