Objective: To explore mothers' and early childhood (EC) educators' experiences of breastfeeding/breast milk provision and breastfeeding support in child care centers (CCCs) in the United States (U.S.).

It is pointed out that such a map does still not exist, but that systematic comparison of some recently produced 3D maps may well be conducive toward this important goal. Hence, the second part of this article is devoted to a detailed comparison of two of such maps, the multimodal MRI-based parcellation of Glasser et al.

Cortical areas have traditionally been defined by their distinctive layer cyto- and/or myelo- architecture using postmortem histology. Recent studies have delineated many areas by measuring overall cortical myelin content and its spatial gradients using the T1w/T2w ratio MRI in living primates, including humans. While T1w/T2w studies of areal transitions might benefit from using the layer profile of this myelin-related contrast, a significant confound is Gibbs' ringing artefact, which produces signal fluctuations resembling cortical layers.

Communication with brain-computer interfaces has been restricted by extensive training requirements and limited accuracy.
Methods: A 45-year-old man with amyotrophic lateral sclerosis (ALS) with tetraparesis and severe dysarthria underwent surgical implantation of four microelectrode arrays into his left ventral precentral gyrus 5 years after the onset of the illness; these arrays recorded neural activity from 256 intracortical electrodes.
