Last month at the annual meeting of the American Association of Physical Anthropologists, researchers debated two solutions to the problem of energetic constraints on brain size and how humans may have evolved a way around them: the expensive tissue hypothesis, which holds that big brains in adults are fueled by the energy saved in humans9 relatively small gastrointestinal tracts (which we can afford because of our high-quality diet), and the maternal investment hypothesis, which proposes that… 
Expensive Brains: “Brainy” Rodents have Higher Metabolic Rate
TLDR
Evidence is provided that brain mass (independent of BM) and BMR are correlated, consistent with the hypothesis that large brains evolve when the payoff for increased brain mass is greater than the energetic cost they incur.
Brain energetics, mitochondria, and traumatic brain injury
TLDR
The connections between energetics and mitochondria – the organelle responsible for almost all the energy production in the cell – and how secondary pathologies in traumatic brain injury result from energetic dysfunction are examined.
Developmental structure in brain evolution
TLDR
Comparison of multiple regressions on allometric data for 131 mammalian species, however, suggests that for 9 of 11 brain structures taxonomic and body size factors are less important than covariance of these major structures with each other.
Emerging concepts of brain function.
TLDR
Some emerging concepts of brain function are discussed and the development of concepts that have been a part of my own research experience are commented on.
Gregariousness increases brain size in ungulates
TLDR
It is found that, after adjusting for body mass, gregariousness and gestation length explained most of the variation in brain mass across the ungulate species studied.
Effects of Prenatal Stress on Structural Brain Development and Aging in Humans
TLDR
The aim of this review is to summarize the existing literature on the consequences of maternal anxiety, stress, and malnutrition for structural brain aging and predisposition for age-associated brain diseases, focusing on studies with human samples.
Mismatch: Why Our World No Longer Fits Our Bodies
We have built a world that no longer fits our bodies. Our genes - selected through our evolution - and the many processes by which our development is tuned within the womb, limit our capacity to
Effects of a secure attachment relationship on right brain development, affect regulation, and infant mental health
Over the last ten years the basic knowledge of brain structure and function has vastly ex- panded, and its incorporation into the developmental sciences is now allowing for more complex and heuristic
Parent-Infant Communication and the Neurobiology of Emotional Development.
The interactive creation of an attachment bond of affective communication between the psychobiologically attuned primary caregiver and the infant is central to human emotional development. These
