A control algorithm for autonomous optimization of extracellular recordings [PDF]

, 2006
This paper develops a control algorithm that can autonomously position an electrode so as to find and then maintain an optimal extracellular recording position.

Morphogen Transport in Epithelia

, 2006
We present a general theoretical framework to discuss mechanisms of morphogen transport and gradient formation in a cell layer. Trafficking events on the cellular scale lead to transport on larger scales. We discuss in particular the case of transcytosis

Aquaporin-4 and brain edema. [PDF]

, 2007
Aquaporin-4 (AQP4) is a water-channel protein expressed strongly in the brain, predominantly in astrocyte foot processes at the borders between the brain parenchyma and major fluid compartments, including cerebrospinal fluid (CSF) and blood.

Cellular Pushing Forces during Mitosis Drive Mitotic Elongation in Collagen Gels

Advanced Science, 2021
Cell elongation along the division axis, or mitotic elongation, mediates proper segregation of chromosomes and other intracellular materials, and is required for completion of cell division.

A mathematical model for calculating the effect of toroidal geometry on the measured magnetic field [PDF]

, 2009
A mathematical model to calculate the measured magnetic field from a stimulated nerve has been presented in the past. Traditionally, electrodes have been used to measure these propagating action signals in nerves, but a less invasive technique is to use ...

ALS-like pathology diminishes swelling of spinal astrocytes in the SOD1 animal model

Frontiers in Cellular Neuroscience
Astrocytes are crucial for the functioning of the nervous system as they maintain the ion homeostasis via volume regulation. Pathological states, such as amyotrophic lateral sclerosis (ALS), affect astrocytes and might even cause a loss of such functions.

Extracellular Glutamate in the Nucleus Accumbens Is Nanomolar in Both Synaptic and Non-synaptic Compartments

Cell Reports, 2017
In the CNS, glutamate is both phasically and tonically released into the extracellular space and must be removed by excitatory amino acid transporters (EAATs) to prevent excitotoxic accumulation.

Brain extracellular space as a diffusion barrier [PDF]

Computing and Visualization in Science, 2011
The extracellular space (ECS) consists of the narrow channels between brain cells together with their geometrical configuration and contents. Despite being only 20-60 nm in width, the ECS typically occupies 20% of the brain volume. Numerous experiments over the last 50 years have established that molecules moving through the ECS obey the laws of ...

Excitable Media Seminar [PDF]

, 2012
The simulation data presented here, and the conceptual framework developed for their interpretation are, both, in need of substantial refinement and extension.
