Selective activation of mesoscale functional circuits via multichannel infrared stimulation of cortical columns in ultra-high-field 7T MRI.

To restore vision in the blind, advances in visual cortical prosthetics (VCPs) have offered high-channel-count electrical interfaces. Here, we design a 100-fiber optical bundle interface apposed to known feature-specific (color, shape, motion, and depth) functional columns that populate the visual cortex in humans, primates, and cats. Based on a non-viral optical stimulation method (INS, infrared neural stimulation; 1,875 nm), it can deliver dynamic patterns of stimulation, is non-penetrating and non-damaging to tissue, and is movable and removable.

Sociodemographic Factors Associated with Purchasing Frozen, Fresh, Canned, and Dried Produce in a Nationally Representative Sample of United States Households.

Background: Frozen fruits and vegetables (FV) are convenient, cost-effective, reduce food waste, and can be just as nutritious as their fresh counterparts. Despite these numerous advantages, it is unclear which consumer segments are more likely to purchase frozen FV, especially compared with fresh, canned, or dried FV, which could help inform targeted nutrition education interventions.

Objective: The objective of this study is to explore sociodemographic factors associated with increased or decreased odds of purchasing frozen, fresh, canned, and dried FV in a nationally representative sample.

Contraceptive use and pregnancy in cystic fibrosis: Survey findings from 10 cystic fibrosis centers.

Background: Reproductive life planning is key, now that people with cystic fibrosis (pwCF) may live into their 60s. This study explores contraceptive use, pregnancy trends, and whether concomitant cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy reduces contraceptive effectiveness.

Methods: Females with CF aged 18-45 years from 10 U.

Autism diagnoses in school-age children in southern Trøndelag 2016-2019.

Background: We have previously reported a significantly higher prevalence of autism spectrum disorders in southern Trøndelag among preschool children with mothers from a different national background than Norway. In this study, we wanted to investigate whether, in the same period and in the same geographic area, there was also an excess prevalence among school-age children. Additionally, we wanted to identify psychiatric and developmental comorbidities.

Multiple loci for foveolar vision in macaque monkey visual cortex.

In humans and nonhuman primates, the central 1° of vision is processed by the foveola, a retinal structure that comprises a high density of photoreceptors and is crucial for primate-specific high-acuity vision, color vision and gaze-directed visual attention. Here, we developed high-spatial-resolution ultrahigh-field 7T functional magnetic resonance imaging methods for functional mapping of the foveolar visual cortex in awake monkeys. In the ventral pathway (visual areas V1-V4 and the posterior inferior temporal cortex), viewing of a small foveolar spot elicits a ring of multiple (eight) foveolar representations per hemisphere.
