Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Different vulnerability of fast and slow cortical oscillations to suppressive effect of spreading depolarization: state-dependent features potentially relevant to pathogenesis of migraine aura

The Journal of Headache and Pain
Background Spreading depolarization (SD), underlying mechanism of migraine aura and potential activator of pain pathways, is known to elicit transient local silencing cortical activity.

Direct Current Coupled Recordings of Cortical Spreading Depression Using Silicone Probes

Frontiers in Cellular Neuroscience, 2017
Electrophysiological assessment of infraslow (<0.1 Hz) brain activities such as cortical spreading depression (SD), which occurs in a number of pathologies including migraine, epilepsy, traumatic brain injury (TBI) and brain ischemia requires direct ...

The continuum of spreading depolarizations in acute cortical lesion development: Examining Leao's legacy. [PDF]

, 2016
A modern understanding of how cerebral cortical lesions develop after acute brain injury is based on Aristides Leao's historic discoveries of spreading depression and asphyxial/anoxic depolarization.

From silence to academic engagement: How refugee children with disabilities access learning through inclusive ‘artful’ schools in Canada

British Educational Research Journal, EarlyView.
Abstract Many newcomer children spend a ‘silent year’ in elementary school classrooms while they adjust to a new culture and language. This often delays inclusion in learning and forming friendships with peers. For refugee children with disabilities (RCDs) this phase may last for 3 years or more, impacting their mental health and sense of belonging ...

Neuronal and astroglial correlates underlying spatiotemporal Intrinsic Optical Signal in the rat hippocampal slice [PDF]

, 2013
Widely used for mapping afferent activated brain areas in vivo, the label-free intrinsic optical signal (IOS) is mainly ascribed to blood volume changes subsequent to glial glutamate uptake.

Neural electrodes for brain‐computer interface system: From rigid to soft

BMEMat, EarlyView.
Here, we review the development trends of neural electrodes in BCI. This paper highlights the critical role of electrodes in BCI systems, analyzes the limitations of rigid electrodes, and introduces various flexible electrodes. Furthermore, we discuss application scenarios and prospects of BCI electrode technology, aiming to provide valuable references

Arachidonic acid metabolites and cortical depression: From local to spatial model [PDF]

Известия Саратовского университета. Новая серия Серия: Физика
Background and Objectives: According to known experimental data, various metabolites of arachidonic acid have a vasoconstrictor or vasodilator effect, which in turn affects neuronal activity.

Front blocking and propagation in cylinders with varying cross section [PDF]

, 2015
In this paper we consider a bistable reaction-diffusion equation in unbounded domains and we investigate the existence of propagation phenomena, possibly partial, in some direction or, on the contrary, of blocking phenomena.
