Recent Advances in Network Electrophysiology Using Multi-Electrode Arrays

Program
6:30 Larry P. Gonzalez, University of Oklahoma Health Sciences Center
Multi-electrode Arrays Allow Determination of Regional Hippocampal Differences in Chronic Ethanol Effects.
Prof Gonzalez will discuss their use of the MED64 probe with an acute hippocampal slice preparation to
investigate the effects of chronic ethanol treatment and withdrawal. Studies to be presented examine evoked responses in hippocampal areas CA1 and CA3 in the presence and absence of carbachol and demonstrate a significant reduction in carbachol-induced paired-pulse facilitation during ethanol withdrawal that is limited to area CA1.

6:55 Suguru Kawato, University of Tokyo
Rapid modulation of hippocampal neuronal plasticity by brain estrogen and endocrine disrupters: an electrophysiological analysis.
Prof Kawato will discuss his recent discovery of the acute effect of neurosteroids on learning and memory. The acute actions of estradiol, BPA and DES were analyzed by measuring the long-term potentiation (LTP) induced upon titanic stimulation of the CA1 pyramidal neurons in rat hippocampal slices. Estradiol and DES enhanced LTP and these effects were suppressed by ERa inhibitor ICI 182,780. BPA, on the other hand, did not affect LTP. These findings suggest that EDs do have significant disrupting actions on learning and memory, and that their enhancing/suppressive effects are depending on individual EDs.

7:20 John Rossi III, Naval Health Research Center, Ohio
Use of a Planar Microelectrode Array System for Evaluation of Changes in Potentials Evoked in Acute Brain Slices from Bluegill Sunfish (Lepomis Macrochirus), Induced by Neurobehavioral Toxicants in Drinking Water.
Dr. Rossi will discuss their development of more flexible detection instrument that can respond over a wide range of toxicant types and concentrations. The system is currently based on acute slices taken from the optic tectum of the bluegill sunfish. The fish slice was chosen because of its relative insensitivity to temperature changes when compared to slices taken from rodent brain. Additionally, the optic tectum slice provides an astonishingly rich subset of receptors to neurotransmitters and neuromodulators.

7:45 Michael Krause, Tensor Biosciences, California
Accelerating Electrophysiology Using Higher-Throughput Multielectrode Arrays.
Dr. Krause will introduce Tensor's Brain-on-a-chip assay technology. Long-term effects of compounds can be studied using brain tissue cultured directly on the MED probe. This assay takes advantage of functional synaptic physiology in these cultured slices and the fact that the same pathway can be recorded over many days. He will also introduce a recently developed multiple Multielectrode Array system. It uses a time-sharing algorithm to simultaneously acquire and process data from 4 or more slice preparations. Applications of this approach in LTP experiments will be discussed.

8:10 Nathan R. Wilson, Picower Center for Learning and Memory, MIT
Exploring Synaptic Interactions and Network Plasticity with Multi-Electrode Devices.
Dr. Wilson will discuss implications and applications of MEA's unique potential for inducing learning across networks of cells via programmable spatiotemporal stimulation. The input-output relationship of neuronal networks is established through the coordinated refinement of synaptic connections. Observing synaptic refinement electrophysiologically requires tools for monitoring currents at the synaptic level while also triggering controlled communication from identifiable neighboring cells. Multi-electrode arrays are ideally suited for this purpose in that they allow for the stimulation of multiple sites in repeatable patterns with high temporal precision.

8:35 Ole Paulsen, University Laboratory of Physiology, Oxford
Network Oscillations Studied Using Planar Multielectrode Arrays.
Dr. Paulsen will discuss their recent results using the MED64 system to record and analyse drug-induced network oscillations in acute hippocampal slices. The powerful combination of the MED64 array with voltage-sensitive dye recording and patch-clamp recordings will be highlighted.
