The kinesin family proteins are often studied as prototypical molecular motors; a deeper understanding of them can illuminate regulation of intracellular transport. It is typically assumed that they function identically. Here we find that this assumption of homogeneous function appears incorrect: variation among motors' velocities in vivo and in vitro is larger than the stochastic variation expected for an ensemble of 'identical" motors. When moving on microtubules, slow and fast motors are persistently slow, and fast, respectively...

The basal ganglia are a collection of nuclei below the cortical surface that are involved in both motor and non-motor functions, including higher order cognition, social interactions, speech, and repetitive behaviors. Motor development milestones that are delayed in autism such as gross motor, fine motor and walking can aid in early diagnosis of autism. Neuropathology and neuroimaging findings in autism cases revealed volumetric changes and altered cell density in select basal ganglia nuclei. Interestingly, in autism, both the basal ganglia and the cerebellum are impacted both in their motor and non-motor domains and recently, found to be connected via the pons through a short disynaptic pathway...

This study examined the effects of a 12-week Comprehensive School Physical Activity Program (CSPAP) on gross motor skill development in children from low-income families. Participants were 1,460 school-aged children (mean age = 8.4 ± 1.8 years; 730 girls, 730 boys) recruited from three schools receiving U.S. governmental financial assistance. Students were recruited from grades K-6. CSPAP was implemented over one semester during the 2014-2015 school year. Select gross motor skill items were assessed during each student's physical education class at baseline and at a 12-week follow-up using the Test for Gross Motor Development-2nd Edition (TGMD-2)...

Vincristine (VNC) is commonly used to treat pediatric cancers, including the most prevalent childhood malignancy, acute lymphoblastic leukemia. Although clinical evidence suggests that VNC causes peripheral neuropathy in children, the degree to which pediatric chemotherapeutic regimens influence pain sensitivity throughout life remains unclear, in part because of the lack of an established animal model of chemotherapy-induced neuropathic pain during early life. Therefore, this study investigated the effects of VNC exposure between postnatal days (P) 11 and 21 on mechanical and thermal pain sensitivity in the developing rat...

Parenting stress has been linked to child development issues in early preterm infants, but less is known about its effects on development in infants born late preterm. We examined relationships between parenting stress of 108 mothers and 108 fathers and development of late preterm infants born at 34 0/7 to 36 6/7 weeks gestation. At 4 months corrected age, mothers and fathers completed the Parenting Stress Index (PSI-3); mothers were primary caregivers in almost all families and completed the Ages and Stages Questionnaire (ASQ-2) on child development...

Seafood intake in pregnancy has been positively associated with childhood cognitive outcomes which could potentially relate to the high vitamin D content of oily fish. However, whether higher maternal vitamin D status (serum 25-hydroxyvitamin D (25(OH)D)) in pregnancy is associated with a reduced risk of offspring suboptimal neurodevelopmental outcomes is unclear. A total of 7065 mother-child pairs were studied from the Avon Longitudinal Study of Parents and Children cohort who had data for both serum total 25(OH)D concentration in pregnancy and at least one measure of offspring neurodevelopment (pre-school development at 6-42 months; 'Strengths and Difficulties Questionnaire' scores at 7 years; intelligence quotient (IQ) at 8 years; reading ability at 9 years)...

BACKGROUND: Premature birth is often associated with neurodevelopmental difficulties throughout childhood. In the first three years of life, the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III) constitute one of the most used tools for assessing child development. Since Bayley-III original norms are based on United States (US) population, it remains uncertain whether their use in other countries (e.g., European) is appropriate. AIMS: This research aimed to examine neurodevelopment of preterm infants and full-term infants, using Bayley-III US norms in comparison to Italian (IT) norms...

Children with autism spectrum disorder (ASD) show significant linguistic and motor impairments compared to children with typical development (TD). Findings from studies of siblings of children with ASD show similarities to conclusions from studies of children with ASD. The current meta-analysis reviewed studies reporting linguistic and/or motor skills in siblings of children with ASD compared to siblings of children with TD. Thirty-four studies published between 1994 and 2016 met all inclusion criteria. We compared three different age groups (12 months or younger, 13 to 24 months, and 25 to 36 months)...

The special sensory, motor, and cognitive capabilities of mammals mainly depend upon the neocortex, which is the six-layered cover of the mammalian forebrain. The origin of the neocortex is still controversial and the current view is that larger brains with neocortex first evolved in late Triassic Mammaliaformes. Here, we report the earliest evidence of a structure analogous to the mammalian neocortex in a forerunner of mammals, the fossorial anomodont Kawingasaurus fossilis from the late Permian of Tanzania...
