The Cortical Signature of Alzheimer's Disease: Regionally Specific Cortical Thinning Relates to Symptom Severity in Very Mild to Mild AD Dementia and is Detectable in Asymptomatic Amyloid-Positive Individuals
(Oxford University Press, 2009)Alzheimer's disease (AD) is associated with neurodegeneration in vulnerable limbic and heteromodal regions of the cerebral cortex, detectable in vivo using magnetic resonance imaging. It is not clear whether abnormalities ... -
Cortical signatures of noun and verb production
(National Academy of Sciences, 2006)Categories like "noun" and "verb" represent the basic units of grammar in all human languages, and the retrieval of categorical information associated with words is an essential step in the production of grammatical speech. ... -
Cortical systems for local and global integration in discourse comprehension
(Elsevier BV, 2013)To understand language, we integrate what we hear or read with prior context. This research investigates the neural systems underlying this integration process, in particular the integration of incoming linguistic information ... -
The Cortical Underpinnings of Context-based Memory Distortion
(MIT Press, 2008)Everyday contextual settings create associations that later afford generating predictions about what objects to expect in our environment. The cortical network that takes advantage of such contextual information is proposed ... -
Cortico-Limbic Response to Personally Challenging Emotional Stimuli After Complete Recovery from Depression
(Elsevier, 2009)People vulnerable to depression are at increased risk of relapse if they live in highly critical family environments. To explore this link, we used neuroimaging methods to examine cortico-limbic responding to personal ... -
Corticospinal Motor Neurons and Related Subcerebral Projection Neurons Undergo Early and Specific Neurodegeneration in \(hSOD1^{G93A}\) Transgenic ALS Mice
(Society for Neuroscience, 2011)Amyotrophic lateral sclerosis (ALS) is characterized by predominant vulnerability and central degeneration of both corticospinal/corticobulbar motor neurons (CSMN; “upper motor neurons”) in cerebral cortex, and spinal/bulbar ... -
Corticospinal Motor Neurons Are Susceptible to Increased ER Stress and Display Profound Degeneration in the Absence of UCHL1 Function
(Oxford University Press, 2015)Corticospinal motor neurons (CSMN) receive, integrate, and relay cerebral cortex's input toward spinal targets to initiate and modulate voluntary movement. CSMN degeneration is central for numerous motor neuron disorders ... -
Corticosterone inhibits GAS6 to govern hair follicle stem-cell quiescence
(Springer Science and Business Media LLC, 2021-03-31)Chronic, sustained exposure to stressors can profoundly impact tissue homeostasis, although the mechanisms by which these changes occur are largely unknown. Here, we report the adrenal gland-derived stress hormone ... -
Corticostriatal pathways contribute to the natural time course of positive mood
(Nature Publishing Group, 2015)The natural time course of mood includes both acute responses to stimuli and spontaneous fluctuations. To date, neuroimaging studies have focused on either acute affective responses or spontaneous neural fluctuations at ... -
Corticothalamic Projection Neuron Development beyond Subtype Specification: Fog2 and Intersectional Controls Regulate Intraclass Neuronal Diversity
(Elsevier BV, 2016)Corticothalamic projection neurons (CThPN) are a diverse set of neurons, critical for function of the neocortex. CThPN development and diversity need to be precisely regulated, but little is known about molecular controls ... -
Cosi fan tutti i compositori: The Cephalus-Procris Myth and the Birth of Romantic Opera in Hoffmann's Aurora

Cosmic flows in the nearby universe from Type Ia supernovae
(Oxford University Press, 2012)Peculiar velocities are one of the only probes of very large scale mass density fluctuations in the nearby Universe. We present new 'minimal variance' bulk flow measurements based upon the 'First Amendment' compilation of ... -
Cosmic Rays from Pulsars and Magnetars
(Wiley-Blackwell, 2010)We compare the expected abundance of cosmic ray electrons and positrons from pulsars and magnetars. We assume that the distribution of infant pulsars and magnetars follows that of high-mass stars in the Milky Way and that ... -
Cosmic reionization by stellar sources: Population II stars
(Oxford University Press, 2003)We study the reionization of the Universe by stellar sources using a numerical approach that combines fast 3D radiative transfer calculations with high-resolution hydrodynamical simulations. By supplementing a one-step ... -
Cosmic reionization by stellar sources: population III stars
(Oxford University Press, 2004)We combine fast radiative transfer calculations with high-resolution hydrodynamical simulations to study an epoch of early hydrogen reionization by primordial stellar sources at redshifts 15less than or similar tozless ... -
Cosmic String Constraints From WMAP and the South Pole Telescope Data
(American Physical Society (APS), 2011)The predictions of the inflationary LCDM paradigm match today's high-precision measurements of the cosmic microwave background anisotropy extremely well. The same data put tight limits on other sources of anisotropy. Cosmic ... -
Cosmic Variance in the Transparency of the Intergalactic Medium after Reionization
(American Astronomical Society, 2006)Following the completion of cosmic reionization, the mean free path of ionizing photons was set by a population of Lyman limit absorbers. As the mean free path steadily grew, the intensity of the ionizing background also ... -
Cosmic X-ray and gamma-ray background from dark matter annihilation
(American Physical Society, 2011)The extragalactic background light (EBL) observed at multiple wavelengths is a promising tool to probe the nature of dark matter. This radiation might contain a significant contribution from gamma-rays produced promptly ... -
Cosmogenic and Nucleogenic 3He in Apatite, Titanite, and Zircon
(Elsevier, 2006)Cosmogenic He-3 was measured in apatite, titanite, and zircon and cosmogenic Ne-21 in quartz at 13 depth intervals in a 2.7-m long drill core in a Miocene ignimbrite from the Altiplano of Bolivia. All three He-3 depth ...
