Efforts to understand the functional architecture of brain have consistently identified multiple overlapping large-scale neural networks that are observable across states. Despite ubiquity these networks, it remains unclear how regions within interact orchestrate behavior. Here, we collected magnetic resonance imaging data from 188 human subjects who engaged in three cognitive tasks and a resting-state scan. Using large sample allowed us use split-sample validations test for replication...
The core feature of an economic exchange is a decision to trade one good for another, based on comparison relative value. Economists have long recognized, however, that the value individual ascribes during making (i.e., their willingness good) does not always map onto reward they actually experience. Here, we show experienced and are represented in distinct regions ventromedial prefrontal cortex (VMPFC) passive consumption rewards. Participants viewed two categories rewards—images faces...

• Thirty-six mucosal specimens were obtained with a biopsy instrument from the upper nasal septum of 12 human autopsy cases before en bloc removal entire olfactory area. Examination these 36 transmission electron microscopy demonstrated epithelium in only 17. A significant negative correlation (<i>r</i>=−.728) was noted between age subject and probability obtaining epithelium, supporting idea that mucosa is gradually replaced by respiratory aging. Using specimens, distribution reconstructed...
During the course of daily activity, our level engagement with world varies on a moment-to-moment basis. Although these fluctuations in vigilance have critical consequences for thoughts and actions, almost nothing is known about neuronal substrates governing such dynamic variations task engagement. We investigated hypothesis that posterior cingulate cortex (CGp), region linked to default-mode processing by hemodynamic metabolic measures, controls variations. recorded activity single neurons...
In this paper, we summarise the outcome of a set experiments aimed at classifying cattle behaviour based on sensor data. Each animal carried sensors generating time series accelerometer data placed collar neck back head, halter positioned side head behind mouth, or ear using tag. The purpose study was to determine how from different placement can classify range typical behaviours. Data were collected and behaviours (grazing, standing ruminating) observed over common frame. Statistical...
The study of stroke patients with modern lesion-symptom analysis techniques has yielded valuable insights into the representation spatial attention in human brain. Here we introduce an approach—multivariate pattern analysis—that no longer assumes independent contributions brain regions but rather quantifies joint contribution multiple determining behavior. In a large sample patients, found patterns damage more predictive neglect than best-performing single voxel. addition, modeling...
According to many studies, the ventromedial prefrontal cortex (VMPFC) encodes subjective value of disparate rewards on a common scale. Yet, host other reward factors-likely represented outside VMPFC-must be integrated construct such signals for valuation. Using functional magnetic resonance imaging (fMRI), we tested whether interactions between posterior VMPFC and functionally connected brain regions predict value. During fMRI scanning, participants rated attractiveness unfamiliar faces. We...
In order to support efficient processing, data must be formatted according standards that are prevalent in the field and widely supported among actively developed analysis tools.The Brain Imaging Data Structure (BIDS) (Gorgolewski et al., 2016) is an open standard designed for computational accessibility, operator legibility, a wide easily extendable scope of modalities -and consequently used by numerous processing tools as preferred input format many fields neuroscience.HeuDiConv (Heuristic...
The G-protein subunit alpha-gustducin, which is similar to rod transducin, has been implicated in the transduction of both sweet- and bitter-tasting substances. In rodents, there are differences sensitivity sweet bitter stimuli different populations taste buds. Rat fungiform buds more responsive salts than stimuli, whereas those on palate respond predominantly contrast, hamster sensitive sweet-tasting stimuli. Taste vallate foliate papillae species compounds. These should be reflected...
1. Mammalian taste receptors are distributed within separate subpopulations, innervated by branches of cranial nerves VII, IX, and X. Most gustatory electrophysiology has focused on input from the fungiform papillae anterior portion tongue, carried chorda tympani branch VIIth nerve. However, only a small percentage buds located in (approximately 18% hamster). There have been no studies hamster's IXth nerve, which innervates greater than 50% its buds, most other nerve function employed...
