CSF from the subarachnoid space moves rapidly into brain along paravascular routes surrounding penetrating cerebral arteries, exchanging with interstitial fluid (ISF) and facilitating clearance of solutes, such as amyloid β, in a pathway that we have termed “glymphatic” system. Prior reports suggested bulk flow or ISF may be driven by arterial pulsation. However, pulsation could not directly assessed. In present study, use vivo two-photon microscopy mice to visualize vascular wall...
Campaigns increasingly implement advergames to engage consumers with a brand through interactive, entertaining media content. However, little research tests the effects of specific features on desired advertising outcomes. This article reports results an experiment designed examine how variation in thematic connection between game associated advergame and affects relationship attitude toward (equated ad) brand. The analysis reveals stronger positive when participants play games high brand's...
Microinfarcts are a common clinical feature of the aging brain, particularly in patients with cognitive decline or vascular Alzheimer's dementia. However, natural history these lesions remains largely unexplored. Here we describe mouse (C57BL/6J) model multiple diffuse microinfarcts induced by unilateral internal carotid artery injection cholesterol crystals (40–70 μm). were spread throughout deep cortex, subcortical tissue, and hippocampus comprised core positive for CD68 (a marker reactive...
Multiband acquisition, also called simultaneous multislice, has become a popular technique in resting-state functional connectivity studies. (MB) acceleration leads to higher temporal resolution but spatially heterogeneous noise amplification, suggesting the costs may be greater areas such as subcortex. We evaluate MB factors of 2, 3, 4, 6, 8, 9, and 12 with 2 mm isotropic voxels, additionally 3.3 single-band acquisitions, on 32-channel head coil. Noise amplification was deeper brain...
Two dhole ( Cuon alpinus ) packs were monitored in Mudumalai Sanctuary, southern India, during 1989‐93 to look at population dynamics, movement pattern, and foraging strategy their inter‐relationship with the maintenance of social groups. Pack size fluctuated substantially (4–18 4–25 two packs) owing dispersal demographic factors such as females not breeding a given year. Both killed much higher proportion chital Axis axis sambar Cervus unicolor fawns (<one year old) than availability...
Abstract The Asiatic wild dog or dhole was once very widely distributed across Asia but now has a fragmented range. In this first genetic study of little‐known species, we obtained information on diversity, phylogeography, and social structure using both mitochondrial control region sequencing microsatellite genotyping noninvasive faecal samples from populations, as well museum captive samples. A pattern largely consistent with isolation by distance the Asian mainland observed, no clear...
Abstract Growing demand for palm oil is driving its expansion into the African tropics, potentially leading to significant carbon emissions if tropical forest converted monoculture. In this first study of a Central concession (31,800 ha), we predict that conversion 11,500 ha logged plantation in Gabon will release 1.50 Tg C (95% CI = [1.29, 1.76]). These could be completely offset over 25 years through sequestration planned set‐asides given 2.6:1 ratio forest. Using an agricultural...
Abstract Two free‐ranging packs of dholes (Asiatic wild dog, Cuon alpinus ) were monitored for a period 6 yr (Sep. 1990‐Sep. 1996) in the Mudumalai sanctuary, southern India. Demographic data on age structure, litter‐size, sex ratio and specific dispersal collected. Behavioural social interactions reproductive behaviour among pack members obtained to determine frequencies dominant subordinate behaviours shown by male female measure each male's access females. Behaviours displayed at dens...
Background: At autopsy, 20%–40% of chronic multiple sclerosis (MS) lesions are labeled “slowly expanding” and feature myelin phagocytosis at the lesion edge. As pathological classification relies on a single, terminal time point, rate expansion cannot be directly measured. Objective: To study long-term volume changes in individual MS lesions. Methods: Volumes proton density magnetic resonance imaging (MRI) acquired between 1992 2015 were measured 22 individuals (one per person). After...
Purpose: To determine and characterize the radiomics features from structural MRI (MPRAGE) Diffusion Tensor Imaging (DTI) associated with presence of mild traumatic brain injuries on student athletes post-concussive syndrome (PCS). Material Methods: 122 (65 M, 57 F), median (IQR) age 18.8 (15-20) years, a mixed level play sports activities, known history concussion clinical PCS, 27 (15 12 20 (19, 21) free athlete subjects were imaged in MR machine. MPRAGE DTI-FA DTI-ADC images used to...
Brain tissue injury caused by mild traumatic brain (mTBI) disproportionately concentrates in the midbrain, cerebellum, mesial temporal lobe, and interface between cortex white matter at sulcal depths
To examine resting-state functional MRI (rs-fMRI) networks related to sleep in the context of HIV infection.rs-fMRI data were collected 40 HIV-infected (HIV+) individuals at baseline (treatment-naive), 12 week (post-treatment) and one year timepoints. A group 50 age-matched HIV-negative (HIV-) also imaged The Pittsburgh Sleep Quality Index (PSQI) questionnaire was administered all Using independent component analysis (ICA), maps generated from fMRI data; these, sleep-related selected....
Surgical intervention often fails to achieve seizure-free results in patients with intractable epilepsy. Identifying features of the epileptic brain that dispose certain unfavorable outcomes is critical for improving surgical candidacy assessments. Recent research by Martinet, Ahmad, Lepage, Cash, and Kramer (J Neurosci 35: 9477-9490, 2015) suggests pathways secondary seizure generalization distinguish favorable (i.e., free) vs. persistent) outcomes, lending insights into network mechanisms...
High angular resolution diffusion imaging (HARDI) is a type of magnetic resonance (dMRI) that measures signals on sphere in q-space. It has been widely used data acquisition for human brain structural connectome analysis. To more accurately estimate the connectome, dense samples q-space are often acquired, potentially resulting long scanning times and logistical challenges. This paper proposes statistical method to select directions optimally local function from sparse observations. The...
INTRODUCTION: Brain-machine interface neuroprosthetic arms for people with upper limb impairment are developing quickly, but could be improved through intelligent computer-vision-based assistance. Grasping and manipulating objects requires very accurate control of a prosthetic arm hand, is required these limbs to eventually used clinically. With the computer helping stabilize hand during grasping, user's would not need as accurate, they free concentrate on larger goals movements. METHODS: A...
