Call for Papers: Extracellular Potentials and Electric Field Interactions

by Reinoud Maex

JOURNAL OF INTEGRATIVE NEUROSCIENCE http://www.worldscinet.com/jin Call for Papers! Special Issue on Extracellular Potentials and Electric Field Interactions In experimental neuroscience, most electric signals are picked up from the electrolytic (or colloidal) solution that constitutes extracellular (interneuronal) space, yet the origin of these potentials is incompletely understood. Even more, theoreticians have recently argued about the physical principles underlying these phenomena. The present special issue invites experimental and theoretical work that can shed light on electric phenomena in extracellular space, with an emphasis on extracellular potentials and endogenous electric field interactions. The contributions solicited are original research papers and comprehensive reviews on methodological aspects. Submission deadline: 30 September 2016 Contact: Dr. Reinoud Maex reinoud.maex(a)ens.fr Questions that may be addressed are (but are not limited to): 1. The nature of extracellular potentials - What is nature of the electric currents, and what is the velocity (distribution) of the ions involved? Since membrane currents underlie the extracellular currents, what are the relative contributions of synaptic versus voltage-gated channels, excitatory versus inhibitory synapses, capacitive currents? How important are Lorenz forces between currents (due to the generated magnetic fields) and is there a contribution of polarization currents? - Is extracellular space purely resistive, or is a capacitive component involved, and what factors (such as ionic concentration, Debye shielding, etc.) contribute to its resistivity? 2. Modeling of extracellular potentials and electric field interactions - What level of detail is needed to model extracellular electrical phenomena, and which formalism can be employed? How valid is the cable equation, or need slow concentration changes of the major ionic components involved be modeled explicitly? How can LFP calculations be incorporated in simulation software? - Can volume transmission be simulated adequately as volume conductors? Are ephaptic coupling effects adequately simulated in one dimension? 3. Neuronal inference from measured extracellular potentials - What is the importance of the electrode characteristics for the proper interpretation of the measured signals? - What are the underlying assumptions, and limitations, of current-source-density analysis? How valid is the dipole approximation? Why are recent experiments being interpreted in terms of monopoles, and can single-compartmental model neurons generate local field potentials at all? - What can be learned from the power density distribution of signal frequencies? 4. Neurostimulation - What is the effect on neurons of an externally applied current or potential, and what mechanism (or rationale) underlies deep brain stimulation? 5. Physiological roles of extracellular potentials and endogenous electrical fields - Do extracellular potentials contribute to neuron-neuron and neuron-glia communication? Can there be a role for extracellular potentials in the homeostasis, clearance, and volume regulation of extracellular space, and in the control of blood flow and of the blood-brain-barrier. - What is the integrative role of endogenous electrical fields in brain function?

Postdoc position

by Dawn Taylor

We currently have openings for postdocs and/or engineers for our NIH-funded study in Parkinson's disease and Deep Brain Stimulation (PIs Dr. Dawn Taylor & Dr. Cameron McIntyre). The goal of this project is to understand how Parkinson's disease alters cortical network processing and how Deep Brain Stimulation (DBS) helps to re-normalize motor function. The project involves chronically recording cortical network activity with high-density electrode arrays in our macaque animal models. Extensive neuromotor data will be collected in the normal and Parkinsonian state as well as on and off different types of DBS. This experimental data will be complimented with computational modeling to try to understand the underlying mechanisms as well as identify ways to improve DBS. We are looking for multiple post docs/engineers that can focus on either the animal work, the computational modeling, or both depending on their skills and interests. If interested, please send a CV to Dr. Dawn Taylor at dxt42(a)case.edu. -- Dawn M.

PhD position in Neurotechnology @ Imperial College

by Chadderton, Paul T

Open PhD position in Neurotechnology at Imperial College London in the Chadderton and Clopath labs. The candidate will be doing in vivo electrophysiology in mouse cerebellum and computational modelling of learning-related changes in this circuit. Candidate must be EU national. Project: Biologically inspired computation for real-time motor control Supervisors: Paul Chadderton (http://neuralcircuitsinbehaviour.squarespace.com/) Claudia Clopath (http://www.bg.ic.ac.uk/research/c.clopath/) An important area of robotics research is focused on developing machines that can learn and adapt to changing environments as efficiently as animals. Biological principles underlying the acquisition of motor skills are likely to inspire these new technologies. The aim of our project is to characterise computational principles of motor learning in real time using novel neurophysiological data from a uniquely tractable and well-controlled system, the whisker circuitry of the cerebellar cortex. Neural recordings will reveal how the brain adapts during learning, and will then be used to develop and apply a biologically constrained computational model in an actively sensing robot.
