The Effects of Stimulator, Waveform, and Current Direction on Intracortical Inhibition and Facilitation: A TMS Comparison Study

Friedhelm Christoph Hummel, Takuya Morishita, Maximilian Jonas Wessel, Laurijn Rianne Draaisma

Background: Cortical function is dependent on the balance between excitatory and inhibitory influences. In the human motor cortex, surrogates of these interactions can be measured in vivo, non-invasively with double-pulse transcranial magnetic stimulation ...

A New Adjustable Glaucoma Drainage Device

Nikolaos Stergiopoulos, Sylvain Roy, Adan Villamarin, Stéphane Bigler

PURPOSE. This work is focused on the testing of a new experimental noninvasively adjustable glaucoma drainage device (AGDD) that allows for the control of its outflow resistance to modulate intraocular pressure (IOP) in a customized fashion. METHODS. Six A ...

Notch signaling in the pigmented epithelium of the anterior eye segment promotes ciliary body development at the expense of iris formation

Freddy Radtke, Friedrich Beermann, Craig Nowell, Bhushan Sarode

The ciliary body and iris are pigmented epithelial structures in the anterior eye segment that function to maintain correct intra-ocular pressure and regulate exposure of the internal eye structures to light, respectively. The cellular and molecular factor ...

A New Noninvasively Adjustable Glaucoma Drainage Device

Adan Villamarin

Glaucoma is an irreversible disease affecting the eye, leading to progressive loss of vision and eventually to total blindness. It is often related to high intraocular pressure (IOP), which results from increased outflow resistance to aqueous humor. The fi ...

Notch Signaling in Pigment Cells and Generation of Mouse Models for Ocular Diseases

Bhushan Sarode

Cellular signaling mediated by Notch receptors results in coordinated regulation of cell growth, survival and differentiation. In melanocytes, Notch signaling is essential for the maintenance of melanocytes and the melanocyte stem cell population. Whereas, ...

Eye Vessel Compliance as a Function of Intraocular and Arterial Pressure and Eye Compliance

Nikolaos Stergiopoulos, Sylvain Roy, Adan Villamarin

PURPOSE. The purpose of our study is to develop and validate a methodology to measure the compliance of the vascular network in the eye using biomechanical parameters, namely arterial pressure, intraocular pressure (IOP), and ocular compliance of the eyeba ...

3D simulation of the aqueous flow in the human eye

Nikolaos Stergiopoulos, Sylvain Roy, Adan Villamarin, Philippe Reymond, Orestis Vardoulis, Reda Hasballa

Glaucoma results in an increase in the resistance of the aqueous humor outflow, which in turn leads to an increase of the intraocular pressure (IOP). Several treatments are proposed to reduce and stabilize the IOP that include medications, filtering surger ...

Producing and Reading Annotations on Paper Documents: a geometrical framework for eye-tracking studies

Pierre Dillenbourg, Frédéric Kaplan, Andrea Mazzei

The printed textbook remains the primary medium for studying in educational systems. Learners use personal annotation strategies while reading. These practices play an important role in supporting working memory, enhancing recall and influencing attentiona ...

Simulation of the Outflow Pathway in the Human Eye

Nikolaos Stergiopoulos, Sylvain Roy, Philippe Reymond, Andreas Schmocker, Orestis Vardoulis

The eye structure and function highly depend on the stability of the intraocular pressure (IOP). Glaucoma is an ophthalmic disease that can potentially lead to irreversible blindness. Glaucoma results from optic nerve damages due to persistent elevated IOP ...

3D simulation of the aqueous flow in the eye

Reda Hasballa

Glaucoma is one of the leading causes of blindness in the world. It results in an increase of the aqueous humour (AH) outflow pathway which leads to an increase of the intraocular pressure (IOP). Many treatments exists to reduce and stabilize the IOP such ...
