Human ventral temporal cortex (VTC) is critical for visual recognition. It is thought that this ability is supported by large-scale patterns of activity across VTC that contain information about visual categories. However, it is unknown how category representations in VTC are organized at the submillimeter scale and across cortical depths. To fill this gap in knowledge, we measured BOLD responses in medial and lateral VTC to images spanning 10 categories from five domains (written characters, bodies, faces, places, and objects) at an ultra-high spatial resolution of 0.8 mm using 7 Tesla fMRI in both male and female participants. Representations in lateral VTC were organized most strongly at the general level of domains (e.g., places), whereas medial VTC was also organized at the level of specific categories (e.g., corridors and houses within the domain of places). In both lateral and medial VTC, domain-level and category-level structure decreased with cortical depth, and downsampling our data to standard resolution (2.4 mm) did not reverse differences in representations between lateral and medial VTC. The functional diversity of representations across VTC partitions may allow downstream regions to read out information in a flexible manner according to task demands. These results bridge an important gap between electrophysiological recordings in single neurons at the micron scale in nonhuman primates and standard-resolution fMRI in humans by elucidating distributed responses at the submillimeter scale with ultra-high-resolution fMRI in humans.

SIGNIFICANCE STATEMENT Visual recognition is a fundamental ability supported by human ventral temporal cortex (VTC). However, the nature of fine-scale, submillimeter distributed representations in VTC is unknown. Using ultra-high-resolution fMRI of human VTC, we found differential distributed visual representations across lateral and medial VTC. Domain representations (e.g., faces, bodies, places, characters) were most salient in lateral VTC, whereas category representations (e.g., corridors/houses within the domain of places) were equally salient in medial VTC. These results bridge an important gap between electrophysiological recordings in single neurons at a micron scale and fMRI measurements at a millimeter scale.

Secondhand smoke exposure poses a significant health risk to nonsmokers. With the proliferation of comprehensive smoke-free laws prohibiting smoking in worksites and public areas, private areas have become the primary source of secondhand smoke exposure for many individuals, particularly youth.

Secondhand smoke exposure in cars has steadily declined among middle and high school students. However, many remain exposed to secondhand smoke in this environment. Jurisdictions should expand existing comprehensive smoke-free policies to prohibit smoking in vehicles occupied by youth. (Read the full article)

The evidence base for obesity prevention is extremely limited. Although minority youth are at higher risk of obesity, and early childhood is a critical period for prevention, only 1 program has demonstrated sustained effects on obesity in young minority children.

Among youth at high risk for obesity based on income, minority status, and child behavior problems, early intervention that promotes effective parenting led to meaningful differences in obesity in preadolescence. Early family intervention is an innovative and promising approach. (Read the full article)

Subjects born preterm have higher blood pressure (BP) in childhood and adolescence. Little is known about at what age the deviation from normal BP starts, and data are especially scarce for the new generation of survivors after extremely preterm birth.

In a population-based study, we found that BP was higher in 2.5-year-old children born extremely preterm compared with controls. This finding might have implications for follow-up programs after preterm birth, with the goal of improving later cardiovascular health. (Read the full article)

Neonatal follow-up programs are designed in part to identify developmental delays among high-risk infants after NICU hospitalization and make referrals to state-funded early intervention. Early intervention has been shown to benefit children with developmental delays.

Many high-risk infants demonstrating developmental delays at neonatal follow-up programs are not referred to early intervention. Subspecialty clinics share responsibility with the medical home in referring children from birth through three years with developmental problems to early intervention services.

Children with a single kidney are often counseled to avoid contact/collision sports based on the concern of injury to the kidney; however, the incidence of kidney injury during sport is not well understood.

Based on this multiyear, prospective injury surveillance system of varsity-level high school athletes, sport-related kidney injury is rare. Reevaluation of American Academy of Pediatrics recommendations regarding sport participation by children with a single kidney is indicated. (Read the full article)

Many drugs are not approved for use in pediatric patients and there is limited evidence on their safety and efficacy in children. Furthermore, there is concern that the quality of pediatric trials is inferior compared with adult trials.

For conditions with a high disease burden in children, only a small proportion of clinical drug trials study pediatric patients. Most pediatric trials are not funded by industry, and the deficiency of evidence is largest in developing countries. (Read the full article)

Declining dietary omega 3 polyunsaturated fatty acids has been associated with rising allergy prevalence and fish oil is therefore of interest in allergy prevention. Supplementation during pregnancy, but not after the age of 6 months, has achieved some allergy reductions.

We assessed the effect of fish oil supplementation from birth to 6 months, which has not been investigated previously. Our results, together with previous findings, will likely help define a "window of opportunity" for allergy intervention using fish oil supplements. (Read the full article)

Rates of screen media use have risen in parallel with rates of obesity among young people. Identifying the specific characteristics of media use that are associated with obesity can help elucidate the explanatory processes and inform effective interventions.

This study examines the associations between BMI and characteristics of media use including the type of device, duration of use, and attention to the medium. The more that participants paid primary attention to television, the higher their BMI. (Read the full article)

Heated, humidified high-flow nasal cannula (HHHFNC) is a noninvasive mode of respiratory support that is commonly used in the majority of US NICUs. No large randomized trial has evaluated safety or efficacy of HHHFNC.

This large randomized controlled trial suggests that HHHFNC is as effective as nCPAP for noninvasive respiratory support and can be safely applied to a wide range of neonates. (Read the full article)

Distracted driving due to texting while driving (TWD) has emerged as an important teenage safety issue. Previous studies have shown that the self-reported prevalence of TWD among teenagers varies widely.

In 2011, 45% of US high school students aged ≥16 years reported TWD during the past 30 days. TWD was positively associated with other risky motor vehicle behaviors; this association strengthened as frequency of TWD increased. (Read the full article)

Elevated blood pressure (BP) has long-term influence on the atherosclerotic process. The relative predictive ability of the standard BP definition endorsed by the National High Blood Pressure Education Program and the recently proposed 2 simplified definitions has not been studied.

Simplified pediatric BP tables predict risk of high adult arterial stiffness as well as the complex table does. These simple screening tools could be used for identifying pediatric subjects at risk and for intervening to improve adult cardiovascular outcomes. (Read the full article)

Pneumonia is the leading cause of death in young children worldwide. Anemia, widely prevalent globally, is not routinely assessed when treating pneumonia. The effect of anemia and high altitude on outcome of pneumonia is not well described.

Anemia at high altitude increases the risk of poor outcome with severe pneumonia. Children with severe pneumonia at high altitude present with more severe hypoxemia and have a longer time to recovery than children at low altitude. (Read the full article)

Higher-hazard, no-benefit research involving children may be approved by local institutional review boards only when the protocol enrolls children with the medical condition under study. The ethics of this distinction have been debated, but parental opinions have not been explored.

We found that parental opinions support federal regulations. We discuss parental motivations for and against research participation and the extent to which enrolling a child in higher-hazard, no-benefit research reflects appropriate surrogate decision-making. (Read the full article)

Preterm infants can be successfully resuscitated with <100% oxygen (O₂); however, initiation with room air remains controversial. Current Neonatal Resuscitation Program (NRP) guidelines suggest using air or blended O₂ to titrate O₂ to meet target preductal saturation goals.

This is the first trial to compare a limited O₂ strategy to target NRP–recommended transitional goal saturations versus a high O₂ strategy in preterm infants. The limited O₂ strategy decreased integrated excess oxygen and oxidative stress and improved respiratory outcomes. (Read the full article)

Shoulder injuries are common among high school athletes. These injuries, both traumatic and overuse, contribute to significant time loss from athletic activity. Understanding sport-specific injury patterns is critical for development of targeted injury prevention programs.
