Are subordinates always stressed? a comparative analysis of rank differences in cortisol levels among primates
TLDR
The meta-analysis identified two variables that significantly predictedrelative cortisol levels: subordinates exhibited higher relative cortisol levels when they were subjected to higher rates of stressors and experienced decreased opportunities for social (including close kin) support. Expand
Cortisol in mother’s milk across lactation reflects maternal life history and predicts infant temperament
TLDR
In monkeys, high cortisol and changes in cortisol levels in mother’s milk are associated with more nervous and less confident infants and mothers may be “programming” behaviorally cautious offspring that prioritize growth through cortisol signaling. Expand
Chronic Intranasal Oxytocin Causes Long-Term Impairments in Partner Preference Formation in Male Prairie Voles
TLDR
Long-term developmental treatment with intranasal OT in the prairie vole resulted in a deficit in partner preference behavior (a reduction of contact with a familiar opposite-sex partner, used to index pair-bond formation) by male voles. Expand
Increased social fear and decreased fear of objects in monkeys with neonatal amygdala lesions
TLDR
Much of the age-appropriate repertoire of social behavior was present in amygdala-lesioned infants indicating that these lesions do not produce autistic-like behavior in monkeys, and amygdala lesions early in development have different effects on social behavior than lesions produced in adulthood. Expand
Comparing cortisol, stress, and sensory sensitivity in children with autism
TLDR
It is proposed that increased sensory sensitivity may enhance the autistic child's susceptibility to the influence of zeitgeibers reflected in variable cortisol secretion, and support a complex interplay between physiological and behavioral stress and sensory sensitivity in autism. Expand
Social Stress Enhances Sympathetic Innervation of Primate Lymph Nodes: Mechanisms and Implications for Viral Pathogenesis
TLDR
It is found that experimentally imposed social stress can enhance the density of catecholaminergic neural fibers within axillary lymph nodes from adult rhesus macaques, defining a novel pathway by which social factors can modulate immune response and viral pathogenesis. Expand
Salivary cortisol and prefrontal cortical thickness in middle-aged men: A twin study
TLDR
Phenotypic and genetic associations of cortisol levels with the thickness of prefrontal and anterior cingulate cortex regions, and with hippocampal volume in a sample of 388 middle-aged male twins who were 51-59 years old remained significant after adjusting for general cognitive ability, cardiovascular risk factors, and depression. Expand
Cortisol circadian rhythms and response to stress in children with autism
TLDR
The results suggest that children with autism process and respond idiosyncratically to novel and threatening events resulting in an exaggerated cortisol response. Expand
Variable cortisol circadian rhythms in children with autism and anticipatory stress.
TLDR
Children with autism showed dysregulation of the circadian rhythm evidenced by variability between groups, between children and within individual child comparisons. Expand
Cross-sectional and 35-year longitudinal assessment of salivary cortisol and cognitive functioning: The Vietnam Era Twin Study of Aging
TLDR
It is found that general cognitive ability at age 20 was a significant predictor of midlife cortisol levels, and possibly support the notion that glucocorticoid exposure is associated with cognitive functions that are mediated by frontal-striatal systems, and is not specific to hippocampal-dependent memory.
