Abstract

Recent physiological evidence shows that in response to stimuli and preceding motor activity, large fields of the upper layers of the cerebral cortex depolarize. It is argued that this finding is a general one and that these dynamic depolarization fields represent the computational elements of the cerebral cortex. Each depolarization field engages many more neurons than do columns and hyper-columns. These fields can be explained by cooperative neuronal computing in layers I-III of the cortex. In these layers, the computing modes might be general for all parts of the cerebral cortex and be sufficiently flexible to handle all sorts of cortical computations, including perception, memory storage, memory retrieval, thought and the production of behavior.

A portable microelectrode array recording system incorporating cultured neuronal networks for neurotoxin detection.

Cultured neuronal networks, which have the capacity to respond to a wide range of neuroactive compounds, have been suggested to be useful for both screening known analytes and unknown compounds for acute neuropharmacologic effects. Extracellular recording from cultured neuronal networks provides a means for extracting physiologically relevant activity, i.e. action potential firing, in a noninvasive manner conducive for long-term measurements. Previous work from our laboratory described prototype portable systems capable of high signal-to-noise extracellular recordings from cardiac myocytes. The present work describes a portable system tailored to monitoring neuronal extracellular potentials that readily incorporates standardized microelectrode arrays developed by and in use at the University of North Texas. This system utilizes low noise amplifier and filter boards, a two-stage thermal control system with integrated fluidics and a graphical user interface for data acquisition and control implemented on a personal computer. Wherever possible, off-the-shelf components have been utilized for system design and fabrication. During use with cultured neuronal networks, the system typically exhibits input referred noise levels of only 4-6 microVRMS, such that extracellular potentials exceeding 40 microV can be readily resolved. A flow rate of up to 1 ml/min was achieved while the cell recording chamber temperature was maintained within a range of 36-37 degrees C. To demonstrate the capability of this system to resolve small extracellular potentials, pharmacological experiments with cultured neuronal networks have been performed using ion channel blockers, tetrodotoxin and tityustoxin. The implications of the experiments for neurotoxin detection are discussed.

How is firing activity of substantia nigra cells regulated? Relevance of pattern-code in the basal ganglia.

The current model of the basal ganglia (BG) assumes that neurons use a firing rate renewal code for movement computing under normal and pathological conditions. Here, we report nonrenewal firing (neuronal firing is influenced by its own previous activity) in cells of the anesthetized rat's substantia nigra (SN). Both compensatory (short interspike intervals (ISIs) are followed by long ISIs and vice versa) and persistent (short and long ISIs cluster for long time periods) nonrenewal activity was found in 52.6% and 33.8% of SN cells, respectively. A compensatory pattern was found in 77.7% of DA cells, but in only 9.8% of GABA-cells. Conversely, a persistent pattern was observed in 74.6% of GABAergic cells and in only 9.9% of DA cells. These findings indicate two types of nonrenewal firing pattern codes specifically present in SN dopaminergic and GABAergic neurons. Disruption of these patterns may play a role in the pathophysiology of basal ganglia disorders such as Parkinson's disease and dyskinesias.

Induction of conduction block by Campylobacter jejuni lipopolysaccharides and focal neural insult.

A systemic exposure to gram negative LPS have caused transient conduction abnormalities in a certain strain of rats probably associated with the action of cytokines secreted by macrophages. Our previous studies demonstrated that anti-GM1 antibodies induced in rats by the cross-reactive Cj-LPS, caused no conduction abnormalities. We designed the present study to evaluate the effect of systemic exposure to Cj-LPS on nerve conduction after a focal minor neural trauma. Female Lewis rats were sensitized against KLH by repetitive subcutaneous injections. After 28 days rats were intraneurally injected with saline in the right sciatic nerve and concomitantly with intraperitoneal Cj-LPS. Sciatic nerve conduction studies were performed on days 0, 1, 2, 3, and 7 after injections. Nerve conduction blocks developed in all the rats (n=10) which received an intraneural injection of saline concomitantly with the systemic Cj-LPS exposure, before titers of anti-ganglioside antibodies were detected. We conclude that humoral factors (possibly cytokines), other than antibodies are secreted by lymphocytes and macrophages stimulated by gram negative LPS, and cause functional conduction abnormalities when the blood-nerve barrier is disrupted.
