Neural activity within the ventromedial prefrontal cortex (vmPFC) is a critical determinant of stressor-induced anxiety. Pharmacological activation of the vmPFC during stress protects against stress-induced social anxiety suggesting that altering the excitatory/inhibitory (E/I) tone in the vmPFC may promote stress resilience. E/I balance is maintained, in part, by endogenous cannabinoid (eCB) signaling with the calcium dependent retrograde release of 2-arachidonoylglycerol (2-AG) suppressing …

Risk and time preferences have often been viewed as reflecting inherent traits such as impatience and self-control. Here, we offer an alternative perspective, arguing that they are flexible and environmentally informed. In Study 1, we investigated risk and time preferences among children in the United States, India, and Argentina, as well as forager-horticulturalist Shuar children in Amazonian Ecuador. We find striking cross-cultural differences in behavior: children in India, the United Stat…

Abstract We study the relation between CEO and employee campaign contributions and find that CEO-supported political candidates receive 3 times more money from employees than candidates not supported by the CEO. This relation holds around CEO departures, including plausibly exogenous departures due to retirement or death. Equity returns are significantly higher when CEO-supported candidates win elections than when employee-supported candidates win, suggesting that CEOs’ campaign contributions…

Tyrosine sulfation is an important post-translational modification found in higher eukaryotes. Here we report an engineered tyrosyl-tRNA synthetase/tRNA pair that co-translationally incorporates O-sulfotyrosine in response to UAG codons in Escherichia coli and mammalian cells. This platform enables recombinant expression of eukaryotic proteins homogeneously sulfated at chosen sites, which was demonstrated by expressing human heparin cofactor II in mammalian cells in different states of sulfat…

Early in human development, children react negatively to receiving less than others, and only later do they show a similar aversion to receiving more. We tested whether theory of mind (ToM) can account for this developmental shift we see in middle childhood. We conducted a face-to-face fairness task that involved a ToM manipulation, measured individual differences in ToM, and collected parent-ratings of children's empathy, a construct related to ToM. We find that greater ToM capacities lead t…

There are many hypotheses regarding specialization of the anterior versus posterior hippocampus including memory encoding versus retrieval and other cognitive processes versus spatial memory. In the present functional magnetic resonance imaging study, we distinguished between the hypothesis linking encoding to the anterior hippocampus and the hypothesis linking spatial memory to the posterior hippocampus by evaluating whether spatial memory encoding involved the anterior hippocampus or the po…

A network is scale-free if its connectivity density function is proportional to a power-law distribution. It has been suggested that scale-free networks may provide an explanation for the robustness observed in certain physical and biological phenomena, since the presence of a few highly connected hub nodes and a large number of small-degree nodes may provide alternate paths between any two nodes on average-such robustness has been suggested in studies of metabolic networks, gene interaction …

The tRNA is a critical component in all modern translation systems as well as an important intermediate in models of early protein coding systems. In the following works, proponents for each of the major hypotheses for tRNA origin and evolution engage in discussion of the merits for each model.

In order to interact appropriately with others, people need to recognize identities, facial expressions, and actions. What are the brain mechanisms underlying this recognition? This project proposes that face identity and expressions are processed by common brain regions, and that distinct regions are specialized to process static and dynamic information. This could be a particular case of a more general phenomenon: ?complementarity?, in which different tasks like recognizing identity and rec…
