The neurotoxic potential of polychlorinated biphenyls (PCBs) depends on the structure of the congener as well as on the age of the exposure. We exposed rats prenatally to a coplanar congener (PCB-77) or to a non-coplanar congener (PCB-47) and measure

The effects of the non-planar polychlorinated biphenyl (PCB) congener 2,2',4,4'-tetrachlorobiphenyl (2,4-TCB) and of the coplanar PCB congener 3,3',4,4'-tetrachlorobiphenyl (3,4-TCB) were investigated on the catecholamine content and release from bov

To investigate the effects of environmental pollutants on neuronal functions in residents of different areas in Germany, a mobile laboratory was developed. The equipment permits the assessment of neurophysiologic as well as neurobehavioral parameters

The object of this study was to compare the postnatal development of mossy fiber potentiation (MFP) and paired-pulse facilitation in the CA3 region of control and lead-exposed rats. The postnatal development of MFP was not influenced by the chronic p

We investigated the effect of thallium ions on extracellular field potentials in the CA1 region of guinea pig hippocampal slices in a matched-pair experimental setup. Somatic and dendritic responses evoked by paired-pulse stimulation of the Schaffer

The effects of inorganic mercury (Hg2+) on calcium channel currents and the potassium-evoked catecholamine release of bovine chromaffin cells in culture were examined. The effects of cadmium (Cd2+), known to block calcium channels and reduce catechol

The medial neurosecretory cells (MNSCs) of the pars intercerebralis in the brain of insects release various hormonal factors that control essential physiological and developmental functions such as moulting, reproduction and metabolism (Wigglesworth,

Using the whole cell patch-clamp technique, calcium (Ca) channel currents from cultured medial neurosecretory cells (MNSCs) of Locusta migratoria (Rössler and Bickmeyer, 1993) were investigated. The calcium channel blocker omega AGA toxin IVA (AGA I

The inhibition by lead of motor terminal calcium plateau signals has been studied using extracellular, perineuronal electrodes applied to the M. triangularis sterni preparation of the mouse. The long-lasting calcium pateau signal induced by 3,4-DAP (

Chronic lead exposure during brain development is known to affect functions of the central nervous system. We exposed rats chronically to low levels of lead at different developmental stages in order to determine the most sensitive periods of the exp
