“…Working memory performance was evaluated using the Y maze task, and logistic regression was employed with volume measurement as a continuous independent variable and percent alteration expressed as a proportion score, bound between the values of 0 and 1, as the dependent variable ( Long, 1997 ). To account for multiple comparisons, raw p -values from each analysis ( n = 6, 3, respectively) were adjusted using the Bonferroni-Holm method ( Holm, 1979 ), a correction commonly used in MRI analysis ( Kerr et al, 2022 ; Straub et al, 2023 ). We opted for this relatively conservative correction method to ensure greater specificity of our findings.…”

“…There has been much research interest in neuroanatomic and functional underpinnings of PNES in the brain. Kerr et al [30] reported that, compared to seizure-naive controls (patients with depression, anxiety, and OCD), patients with PNES had a bilaterally thinner superior temporal cortex, thicker left lateral occipital cortex, and greater left cerebellar white-matter volume. Using similar imaging methods, Zelinski et al [31] investigated the relationship of gray matter variations with clinical features.…”

“…In research settings, it is customary to recruit "healthy", "cognitively normal", or "unaffected" participants explicitly for this purpose. For clinically-acquired MRIs, a control group might be composed of demographically-matched patients who underwent brain MRIs to rule out serious neuropathology and were found to have unremarkable MRIs (Kerr et al 2022). A critical and unresolved question is whether the difference in ascertainment process between research-controls and clinical-controls biases inferences about patient groups of interest.…”
