“…These results have sparked proposals that different mechanisms underlie processing during feature and conjunction-based searches. By many accounts, mechanisms for processing items that are defined by a single feature, and therefore "pop-out" among distractors, are believed to be innate or develop within the first months of life, whereas more difficult conjunction search depends upon more complex cognitive mechanisms related to the prefrontal cortex, such as executive functions that develop later in life (Gerhardstein & Rovee-Collier, 2002;Merrill & Lookadoo, 2004; see Pelegrina et al, 2020 for some relevant evidence regarding ERP's).…”

In foraging tasks multiple targets must be found within a single display. The targets can be of one or more types, typically surrounded by numerous distractors. Visual attention has traditionally been studied with single target search tasks but adding more targets to the search display results in several additional measures of interest, such as how attention is oriented to different features and locations over time. We measured foraging among five age groups:Children in grades 1, 4, 7, and 10, as well as adults, using both simple feature foraging tasks and more challenging conjunction foraging tasks, with two target types per task. We assessed participants' foraging organization, or systematicity when selecting all the targets within the foraging display, on four measures: Intertarget distance, number of intersections, best-r, and

“…[ 16 ] In some patients, there may be evidence of functional iron deficiency (low iron saturation and normal or high ferritin levels). [ 17 ] WM cells can produce hepcidin, which is a regulator of serum iron content, inducing a mixture of absolute and functional iron deficiency. [ 18 ] In these cases, intravenous iron supplementation can improve the anemia and delay WM directed treatment.…”

Rationale: It is very likely that we will miss Bing-Neel syndrome (BNS) when its initial sign is anemia. Patient concerns: A 59-year-old woman presented with episodic loss of consciousness, anemia, and extremity muscle strength scores (5-) and extremity tendon reflexes (++).Diagnoses: Magnetic Resonance Imaging (MRI) showed abnormal signal in the left hippocampus, left insula, and right occipital lobe. Quantitative serum immunoglobulins showed elevated immunoglobulinm (IgM) (60.6g/L). Bone marrow biopsy showed lymphoplasmacytic lymphoma (LPL) and tested positive for the MYD88 L265P mutation suggesting Waldenström macroglobulinemia (WM).Interventions: The patient underwent 3 plasma exchange treatments in the department of hematology followed by chemotherapy (cyclophosphamide for injection, bortezomib for injection).

“…In addition, to avoid possible long-lasting effects due to online processing of the sample numerosity, a new baseline correction was computed using the last 100 ms before stimulus offset (from 200 to 300 ms after sample stimulus onset). Such baseline correction has been commonly performed in match-to-sample paradigms ( Barriga-Paulino et al, 2014 , 2015 ; Pelegrina et al, 2020 ) in order to reduce the impact of stimulus encoding and highlight information maintenance during the delay period. A 50-ms long negative peak component was found after the stimulus offset at around 250 ms, followed by a 50-ms positive component.…”

Electrophysiological Signatures of Numerosity Encoding in a Delayed Match-to-Sample Task

The number of elements in a small set of items is appraised in a fast and exact manner, a phenomenon called subitizing. In contrast, humans provide imprecise responses when comparing larger numerosities, with decreasing precision as the number of elements increases. Estimation is thought to rely on a dedicated system for the approximate representation of numerosity. While previous behavioral and neuroimaging studies associate subitizing to a domain-general system related to object tracking and identification, the nature of small numerosity processing is still debated. We investigated the neural processing of numerosity across subitizing and estimation ranges by examining electrophysiological activity during the memory retention period in a delayed numerical match-to-sample task. We also assessed potential differences in the neural signature of numerical magnitude in a fully non-symbolic or cross-format comparison. In line with behavioral performance, we observed modulation of parietal-occipital neural activity as a function of numerosity that differed in two ranges, with distinctive neural signatures of small numerosities showing clear similarities with those observed in visuospatial working memory tasks. We also found differences in neural activity related to numerical information in anticipation of single vs. cross-format comparison, suggesting a top-down modulation of numerical processing. Finally, behavioral results revealed enhanced performance in the mixed-format conditions and a significant correlation between task performance and symbolic mathematical skills. Overall, we provide evidence for distinct mechanisms related to small and large numerosity and differences in numerical encoding based on task demands.
