The extent of observed conduction delays in dysmyelinated rat fibers was dependent on frequency of stimulation, with high frequency stimulation resulting in larger and more variable delays than low frequency.
“Furthermore, the extent of the observed conduction delays were found to be dependent on the frequency of stimulation, with high frequency stimulation resulting in larger and more variable conduction delays than low frequency stimulation.”

“In some, but not all, individuals with psychotic symptoms, RL deficits can be linked to aberrant VS RPE signals at the neural level (Maia & Frank, 2017; Murray et al., 2008) and, potentially, to increased presynaptic dopamine function at the neurochemical level (Boehme et al., 2015).”

“CSN is linked with the mesostriatal dopaminergic system (Murray et al. 2008; Palaniyappan & Liddle, 2012; Raij et al. 2015) and, thus, the mesostriatal hyperdopaminergic state observed in psychosis (Howes et al. 2012) may be linked to CSN functioning.”

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.
