Brains, genes and environment of suicide attempters
Identification of symptoms or biological abnormalities that predispose to suicide or identifies specific vulnerabilities, may one day improve allocation of resources or help tailor treatment to the patient. Paper I: We compared the predictive value of symptom-oriented questions against direct …

Development of language in the minds and brains of children
… to measure language-evoked activation in the brains of awake toddlers, an under-studied age group in fMRI research that represents a critical period of time in language development. Using this task in adults, we found no difference in canonical language regions’ responses to speech in dialogue …

Caste-Specific Expression Of Coding And Noncoding Genes In Ant Brains
… how caste-specific gene expression in ant brains affects phenotype and develop a method to study R-loops, a potential mechanism of lncRNAs. The first section describes how we improved the contiguity of the Harpegnathos genome using PacBio long-read sequencing technology, enabling the …

Preparation, characterisation and transcriptome analysis of RNA frm human vCJD brains.
… A method for the isolation of RNA from vCJD brains which minimized infectivity and reduced Proteinase K resistant prion protein levels to undetectable by biochemical assay was developed. RNA preparations were made from sample of the frontal parasagital cortex, sub-frontal cortex and …

Subconcussive blows in high school football : putting young brains at risk
… shocking and wholly unexpected. Players' brains were significantly changing even in the absence of concussions, due to an accumulation of smaller impacts called subconcussive blows. Years of subsequent research have only confirmed their initial results-season after season, they found that …

Wandering minds, restless brains and mindful thinking : a network-based perspective
People vary significantly across multiple cognitive domains, and that variation may be related to individual differences in the intrinsic functional architecture of the human brain. Such individual differences can be characterized via resting-state measurement of temporal synchrony between brain …

From brains to bears. understanding brain size evolution: causes, costs and benefits
Developmental and energetic costs result in brains being expensive organs to grow and maintain, yet large brains have evolved in many mammalian species. The adaptive value of increased brain size has come under scrutiny over the past few decades and despite considerable research effort, much …

Abnormal Anatomy of the Auditory Cortex in Schizophrenic Brains with Auditory Hallucinations
… considering volumetric variance in pathologic brains with AH, there is a paucity of data considering the influence of morphology and surface area of primary auditory structures. Purpose: The purpose of this set of studies was to evaluate and compare the following variables in schizophrenic and …

Imagining the Voltage of Neurons Distributed Across Entire Brains of Larval Zebrafish
… of imaging voltage of neurons distributed across brains. However, due to the high imaging speed and signal-to-noise ratio requirements of GEVIs, microscopy hardware to date has only been able to image the voltage of neurons within subregions of the brain, even for small animals like the larval …

Aging Lowers Pex5 Levels In Cortical Neurons In Male and Female Mouse Brains
… expressed, and 3) in the cortices of aged mouse brains.</p> <p>First, we found that the rate of peroxisomes being moved to acidic lysosomes increased in a neuronal HD model compared to control neurons, indicating that mHtt expression amplified the peroxisomal degradation process. We also found …

Perinatal Nicotine Exposure and Programming of HIE Sensitive Phenotype in Neonatal Rat Brains
Large epidemiological and animal studies have revealed a clear association of adverse intrauterine environment with the increased risk of metabolic, cardiovascular and neurological diseases. Maternal smoking is the single most widespread perinatal insult in the world and has been associated with …

Minding the empathy gap : how insights into brains and behaviors are placating polarization
The One America Movement is a nonprofit, bridge-building organization founded after the 2016 presidential election. The organization is committed to combating toxic polarization all over the country. On January 27, 2019, One America organized a meeting in South Jordan, Utah in which Latter-day …

Stab Wounds to Rat Brains : Demyelination, Remyelination and the Cellular Response, Particularly of Oligodendrocytes
<p>The present body of knowledge concerning the results of central nervous system injury is incomplete and controversial. The role of oligodendrocytes, the cells involved in phagocytosis, the stages of demyelination, and the evidence for remyelination are of interest. Following stab wounds to rat …

Burning flames and seething brains: Passion, imagination, and madness in Karamzin, Pushkin, and Gogol
My thesis begins with an overview of sensibility (chuvstvitel'nost') and passion (strast') in Russian Sentimentalism, with a focus on the prose fiction of Nikolai Karamzin. After describing the correlation between passion and madness (a commonplace of eighteenth- and early-nineteenth-century …

The isolation, partial purification and preliminary characterization of a growth factor from chick embryo brains
… is a mitogen isolated from embryonic chick brains thought to have a potential role as a trophic factor involved in nerve dependent amphibian limb regeneration. In addition, CBGF stimulates 3H-thymidine incorporation in chick embryo brain astrocytes in vitro. In this study, cultured chick …

Decoding brains by paying attention: An attention-based fMRI task state decoding deep network architecture
One of the core goals in the field of cognitive neuroscience is to decode task state fMRI data. Task decoding is the process of taking neuroimaging data and determining the task that was performed when that data was collected. A large volume of work used for task decoding is done in pursuit of …

An investigation into variations in the venous drainage pattern in brains of adolescents and adults
It is well established that the brain changes dramatically in appearance during gestation and even after birth. Due to the multi-channelled origins and the number of developmental options, the adult venous system is characterised by a higher incidence of anatomical variations than the arterial …

Big Brains and Small Teeth: a primate comparative approach to dental and mandibular reduction in hominins
Within the genus Homo, we observe a decrease in mandibular robusticity and in the size of anterior and postcanine dentition, a trend that is usually referred to as reduction or gracilisation. Factors linked to diet, food processing and encephalization have been suggested to be the main drivers of …
