Abstract

Seizures during development are a relatively common occurrence and are often associated with poor cognitive outcomes. Recent studies show that early life seizures alter the function of various brain structures and have long-term consequences on seizure susceptibility and behavioral regulation. While many neocortical functions could be disrupted by epileptic seizures, we have concentrated on studying the prefrontal cortex (PFC) as disturbance of PFC functions is involved in numerous co-morbid disorders associated with epilepsy. In the present work we report an alteration of short-term plasticity in the PFC in rats that have experienced early life seizures. The most robust alteration occurs in the layer II/III to layer V network of neurons. However short-term plasticity of layer V to layer V network was also affected, indicating that the PFC function is broadly influenced by early life seizures. These data strongly suggest that repetitive seizures early in development cause substantial alteration in PFC function, which may be an important component underlying cognitive deficits in individuals with a history of seizures during development.

  • FLE seizures can cause structural and functional damage of the prefrontal areas including altered short-term plasticity.

    “And eventually the FLE seizures can cause structural and functional damage of the prefrontal areas including altered short-term plasticity [389, 390].”

    From Development of prefrontal cortex (2022) · cites this paper as [390]

    The Discussion (page unavailable) reports that early-life generalized seizures altered short-term plasticity in the prefrontal cortex of rats. The Introduction (page unavailable) also reports prefrontal architectural changes from an earlier study. This paper does not establish that frontal lobe epilepsy (FLE) seizures cause structural damage, so the claim extends beyond its evidence. (LLM, conf=0.88)

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.
