We describe convergent evidence from transcriptomics, morphology and physiology for a specialized GABAergic neuron subtype in human cortex. Using unbiased single nucleus RNA sequencing, we identify ten GABAergic interneuron subtypes with combinatorial gene signatures in human cortical layer 1 and characterize a novel group of human interneurons with anatomical features never described in rodents having large, “rosehip”-like axonal boutons and compact arborization. These rosehip cells show an immunohistochemical profile (GAD1/CCK-positive, CNR1/SST/CALB2/PVALB-negative) matching a single transcriptomically-defined cell type whose specific molecular marker signature is not seen in mouse cortex. Rosehip cells in layer 1 make homotypic gap junctions, predominantly target apical dendritic shafts of layer 3 pyramidal neurons and inhibit backpropagating pyramidal action potentials in microdomains of the dendritic tuft. These cells are therefore positioned for potent local control of distal dendritic computation in cortical pyramidal neurons.

We present two studies that together test a fundamental yet rarely examined assumption underlying the contemporary appeal of authenticity—namely, that consumers assign higher value ratings to organizations regarded as authentic. Study 1 conducts content analysis of unsolicited online restaurant reviews entered voluntarily by consumers in three major U.S. metropolitan areas from October 2004 to October 2011; the data contain information from 1,271,796 reviews written by 252,359 unique reviewers of 18,869 restaurants. The findings show that consumers assign higher ratings to restaurants regarded as authentic, even after controlling for restaurant quality in several ways. In addition, we find that consumers perceive independent, family-owned, and specialist (single-category) restaurants as more authentic than they do chain, non-family-owned, and generalist (multiple-category) restaurants. Study 2 reinforces these findings using an experimental design in which participants were presented with photos and minimal descriptions of fictitious restaurants and then asked to evaluate the likely authenticity, quality, and overall value of the restaurants in a predetermined sequence. Central to both studies is an authenticity scale that was developed through the use of an online survey that ascertains the specific language used by individuals in referencing authenticity in the restaurant domain. Taken together, these studies demonstrate that authenticity generates higher consumer value ratings of organizations; the studies also identify certain types of organizations that are more likely to receive authenticity attributions by consumers.

AbstractWe propose a synthesis of two lines of sociological research on boundary spanning in cultural production and consumption. One, research on cultural omnivorousness, analyzes choice by heterogeneous audiences facing an array of crisp cultural offerings. The other, research on categories in markets, analyzes reactions by homogeneous audiences to objects that vary in the degree to which they conform to categorical codes. We develop a model of heterogeneous audiences evaluating objects that vary in typicality. This allows consideration of orientations on two dimensions of cultural preference: variety and typicality. We propose a novel analytical framework to map consumption behavior in these two dimensions. We argue that one audience type, those who value variety and typicality, are especially resistant to objects that span boundaries. We test this argument in an analysis of two large-scale datasets of reviews of films and restaurants.
