The following recent paper may be of interest to those in this list
interested in new methods to study in-vitro network operations.
A new planar multielectrode array for extracellular recording:
application to hippocampal acute slice
Journal of Neuroscience Methods, 93, 61-67.
Abstract
The present paper describes a new planar multielectrode array (the MED
probe) and its electronics (the MED system) which perform
electrophysiological studies on acute hippocampal slices.
The MED probe has 64 planar microelectrodes, is covered with a
non-toxic, uniform insulation layer, and is further coated with
polyethylenimine and serum.
The MED probe is shown to be appropriate for both stimulation and
recording. In particular, multi-channel recordings of field EPSPs
obtained by stimulating with a pair of planar microelectrodes were
established for rat hippocampal acute slices. The recordings were stable
for six hours. Finally a spatial distribution of long-term potentiation
was studied using the MED system
