Medial vestibular nucleus in the guinea-pig
Summary In the preceding paper, medial vestibular nuclei neurones (MVNn) were shown to belong to two main classes, A MVNn and B MVNn, depending on their membrane properties in brainstem slices. In the following study we attempted to confirm this segregation by studying some of the ionic conductances...

In the following study we attempted to confirm this segregation by studying some of the ionic conductances that these cells are endowed with. Type A MVNn demonstrated small high threshold calcium spikes that could be potentiated by barium, a 4-AP resistant A-like conductance and a calcium-dependant afterhyperpolarization. Type B MVNn, in contrast, had large high threshold calcium spikes and prolonged calcium-dependant plateau potentials. In addition, they had a calcium-dependant afterhyperpolarization as well as a subthreshold persistent sodium conductance. A subpopulation of B MVNn had also low threshold calcium spikes that gave them bursting properties. These data confirm the segregation of MVN neurones into two main classes and will be discussed with respect to the firing characteristics of vestibular neurones in vivo. | ||

Medial vestibular nucleus in the guinea-pig |
| abstract |
Summary In the preceding paper, medial vestibular nuclei neurones (MVNn) were shown to belong to two main classes, A MVNn and B MVNn, depending on their membrane properties in brainstem slices. In the following study we attempted to confirm this segregation by studying some of the ionic conductances that these cells are endowed with. Type A MVNn demonstrated small high threshold calcium spikes that could be potentiated by barium, a 4-AP resistant A-like conductance and a calcium-dependant afterhyperpolarization. Type B MVNn, in contrast, had large high threshold calcium spikes and prolonged calcium-dependant plateau potentials. In addition, they had a calcium-dependant afterhyperpolarization as well as a subthreshold persistent sodium conductance. A subpopulation of B MVNn had also low threshold calcium spikes that gave them bursting properties. These data confirm the segregation of MVN neurones into two main classes and will be discussed with respect to the firing characteristics of vestibular neurones in vivo. |

In the following study we attempted to confirm this segregation by studying some of the ionic conductances that these cells are endowed with. Type A MVNn demonstrated small high threshold calcium spikes that could be potentiated by barium, a 4-AP resistant A-like conductance and a calcium-dependant afterhyperpolarization. Type B MVNn, in contrast, had large high threshold calcium spikes and prolonged calcium-dependant plateau potentials. In addition, they had a calcium-dependant afterhyperpolarization as well as a subthreshold persistent sodium conductance. A subpopulation of B MVNn had also low threshold calcium spikes that gave them bursting properties. These data confirm the segregation of MVN neurones into two main classes and will be discussed with respect to the firing characteristics of vestibular neurones in vivo.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Springer Online Journal Archives 1860-2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Serafin, M.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Waele, C.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Khateb, A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Vidal, P.
