Abstract

In experimentally damaged inner ears the structural alterations were correlated to electrocochleographic responses of the ear. Sectioning of the cochlear nerve with degeneration of the type I neurons but intact sensory cells results in normal cochlear microphonics but very weak and atypical nerve responses. By contrast, damage of the organ of Corti with retrograde degeneration abolished primarily the cochlear microphonics, whereas the compound VIII nerve action potential is barely affected when only the outer hair cells are gone and even a small number of surviving inner hair cells is still compatible with a relatively strong compound action potential of the cochlear nerve.

Chronic coadministration of olanzapine and fluoxetine activates locus coeruleus neurons in rats: implications for bipolar disorder.

RATIONALE: The depressive phase of bipolar disorder (bipolar depression) is a difficult-to-treat form of depression. The olanzapine/fluoxetine combination (Symbyax) is the only medication approved to treat this disorder. The precise neural mechanisms responsible for its efficacy are not clearly understood. OBJECTIVES: In order to further elucidate the neurobiological mechanisms responsible for the beneficial clinical effects of the olanzapine/fluoxetine combination, the current experiment was designed to investigate the effects of chronic coadministration of olanzapine and fluoxetine on electrophysiological activity in the locus coeruleus (LC). METHODS: Rats received olanzapine for 3 weeks via subcutaneous osmotic pumps while simultaneously receiving daily intraperitoneal injections of fluoxetine. These chronically treated rats were anesthetized, and single-unit recordings of LC neurons were made. RESULTS: Chronic administration of olanzapine alone significantly increased firing of LC neurons, while, as reported previously, chronic administration of fluoxetine alone significantly reduced firing of LC neurons. However, in the combination condition, olanzapine was able to block the fluoxetine-induced suppression of the LC, and a significant increase in LC activity was observed. CONCLUSIONS: The observed increase in firing of LC neurons could lead to enhanced levels of norepinephrine release in projection areas and amelioration of the clinical symptoms of bipolar depression.

Electrophysiological alterations in subthalamic neurons after unilateral dopamine depletion in the rat.

The present study examined the effects of unilateral 6-hydroxydopamine (6-OHDA) lesions of the substantia nigra pars compacta (SNc) on electrophysiological properties of subthalamic neurons (STN) in adult rats. Most neurons displayed regular spontaneous tonic firing patterns in both control and lesioned animals; however, the percentage of neurons with spontaneous burst firing at hyperpolarized membrane potentials was increased significantly in lesioned animals compared with controls (45% vs. 14% respectively). In the presence of bicuculline, a gamma-aminobutyric acid type A (GABAA) receptor antagonist, electrical stimulation of the internal capsule produced monosynaptic excitatory postsynaptic potentials (EPSPs) in almost all recorded neurons. DA (50 microM) increased the amplitude and/or duration of the EPSPs in neurons from both groups, whereas the DA D1 receptor agonist SKF 81297 (10 microM) produced a significant increase in amplitude and/or duration of EPSPs in neurons from the lesioned group only. This latter increase was blocked by pretreatment with the DA D1 antagonist SCH 23390 (10 microM). These data suggest that unilateral degeneration of DA neurons in the SNc changes firing properties and enhances electrophysiological responsiveness of STN neurons to activation of DA D1 receptors.

In vitro cortical neuronal networks as a new high-sensitive system for biosensing applications.

By taking advantages of the main features of the microelectrode array (MEA) technology (i.e. multisite recordings, stable and long-term coupling with the biological preparation), we analyzed the changes in activity patterns induced by applying specific substances to dissociated cortical neurons from rat-embryos (E18). Data were recorded simultaneously from 60 electrodes, and the electrophysiological behavior was investigated during the third week in vitro, both at the spike and burst level. The analysis of the electrophysiological activity modulation, by applying agonists of the ionotropic glutamate receptors at low (i.e. 0.2-1-5 microM) and high (i.e. 50-100 microM) concentrations, is presented. Preliminary results show that the dynamics of the in vitro cortical neurons is very sensitive to pharmacological manipulation of the glutamatergic transmission and the effects on the network behavior are strictly dependent from the drug concentration. In particular, the addition of a high-dose of agonist determined a global and irreversible depression of the network activity, while, in the low-concentration case, the electrophysiological behavior showed different results, depending on the type of receptor involved. From these observations, we are encouraged to think of a more engineered system, based on in vitro cortical neurons, as a novel sensitive system for drug (pre)-screening and neuropharmacological evaluations.
