Extent of hypoattenuation on CT angiography source images in Basilar Artery occlusion: prognostic value in the Basilar Artery International Cooperation Study [PDF]

, 2011
<p><b>Background and Purpose:</b> The posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) quantifies the extent of early ischemic changes in the posterior circulation with a 10-point grading system.

Perineuronal Nets and GABAergic cells in the Inferior Colliculus of Guinea Pigs

Frontiers in Neuroanatomy, 2014
Perineuronal nets (PNs) are aggregates of extracellular matrix that have been associated with neuronal plasticity, critical periods, fast-spiking cells and protection from oxidative stress.

Sensory prediction errors in the human midbrain signal identity violations independent of perceptual distance

eLife, 2019
The firing of dopaminergic midbrain neurons is thought to reflect prediction errors (PE) that depend on the difference between the value of expected and received rewards.

Essential role for PDGF signaling in ophthalmic trigeminal placode induction [PDF]

, 2008
Much of the peripheral nervous system of the head is derived from ectodermal thickenings, called placodes, that delaminate or invaginate to form cranial ganglia and sense organs.

Mesencephalic basolateral domain specification is dependent on Sonic Hedgehog

Frontiers in Neuroanatomy, 2015
In the study of central nervous system morphogenesis, the identification of new molecular markers allows us to identify domains along the antero-posterior and dorso-ventral axes.

Leptin and Insulin Signaling in Dopaminergic Neurons: Relationship between Energy Balance and Reward System

Frontiers in Psychology, 2014
The central actions of leptin and insulin are essential for the regulation of energy and glucose homeostasis. In addition to the crucial effects on the hypothalamus, emerging evidence suggests that the leptin and insulin signaling can act on other brain ...

Snail2 directly represses cadherin6B during epithelial-to-mesenchymal transitions of the neural crest [PDF]

, 2007
The neural crest, a transient population of migratory cells, forms the craniofacial skeleton and peripheral nervous system, among other derivatives in vertebrate embryos. The transcriptional repressor Snail2 is thought to be crucial for the epithelial-to-

Cortical transformation of spatial processing for solving the cocktail party problem: a computational model(1,2,3). [PDF]

, 2016
In multisource, "cocktail party" sound environments, human and animal auditory systems can use spatial cues to effectively separate and follow one source of sound over competing sources.

Neurosensory development of the four brainstem-projecting sensory systems and their integration in the telencephalon

Frontiers in Neural Circuits, 2022
Somatosensory, taste, vestibular, and auditory information is first processed in the brainstem. From the brainstem, the respective information is relayed to specific regions within the cortex, where these inputs are further processed and integrated with ...
