Whole cell and single channel Ca2+ currents were compared for hippocampal neurons of normal and ethanol-tolerant long-sleep and short-sleep mice. The properties of these currents were equivalent for normal LS and SS mice. In contrast, the peak amplitude of the whole cell Ca2+ current increased significantly for neurons isolated from LS but not SS mice(More)
The whole cell recording technique was used to explore the depressant effect of the tricyclic antidepressant imipramine (IP) on calcium currents of neurons in cultures of murine dorsal root ganglia. The maximal whole cell current (ICa) mediated by the L-type calcium channel declined to 54% of control within 3 min of superfusing neurons with a solution(More)
Synaptic vesicles aggregate at the presynaptic terminal during synapse formation via mechanisms that are poorly understood. Here we have investigated the role of the putative calcium sensor synaptotagmin I in vesicle aggregation during the formation of soma-soma synapses between identified partner cells using a simple in vitro synapse model in the mollusc(More)
1. Voltage-activated currents through calcium channels in primary cultures of murine dorsal root ganglion cells (DRG) were studied with the whole-cell and cell-attached patch recording techniques. 2. The chemical phosphatase 2,3-butanedione monoxime (BDM) reversibly reduced the amplitude of L-type calcium current (ICa) in a dose-dependent manner; at a(More)
The high cost of large animal protocols has limited the study of distraction osteogenesis (DO) in the craniofacial region. This study was designed to characterise a rat model for DO with regard to distraction rate and consolidation period. Unilateral mandibular distraction was performed on 129 male Sprague-Dawley rats using an osteotomy from the sigmoid(More)
Whole-cell and single-channel recording techniques were used to investigate the acute, in vitro effects of ethanol on the function of voltage-activated Ca2+ channels in cultured neurons derived from dorsal root ganglia (DRG) of embryonic mice. Although 5.4 mM ethanol produced a sustained increase of the amplitude of the whole-cell Ca2+ current (ICa), 43.2(More)
