Learning-induced intrinsic and synaptic plasticity in the rodent medial prefrontal cortex
Open accessAbstract
In rodents, the anterior cingulate (ACC), prelimbic (PL), and infralimbic cortex (IL) comprise the medial prefrontal cortex (mPFC). Through extensive connections with cortical and subcortical structures, the mPFC plays a key modulatory role in the neuronal circuits underlying associative fear and reward learning. In this article, we have compiled the evidence that associative learning induces plasticity in both the intrinsic and synaptic excitability of mPFC neurons to modulate conditioned fear and cocaine seeking behavior. The literature highlights the accumulating evidence that plasticity in the intrinsic excitability of mPFC neurons represents a major cellular mechanism that interacts with synaptic changes to alter the impact of the mPFC on fear and reward circuits.

The mPFC has reward-regulated mechanisms of spatial learning.
“The mPFC has an integrative role in object, place and time information [114, 115] as well as reward-regulated mechanisms of spatial learning [116, 117].”
From The extracellular matrix and perineuronal nets in memory (2022) · cites this paper as [116]
The Abstract (page unavailable) describes mPFC plasticity in reward learning, and the Cocaine section discusses cocaine-conditioned place preference. Neither passage establishes that reward regulates mechanisms of spatial learning; the review addresses reward learning and drug seeking instead. (LLM, conf=0.78)

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.
