Chemical anoxia activates ATP-sensitive and blocks Ca2+- dependent K+ channels in rat dorsal vagal neurons in situ (2002)

Kulik,A., Brockhaus,J., Pedarzani,P., Ballanyi,K.

The contribution of subclasses of K+ channels to the response of mammalian neurons to anoxia is not yet clear. We investigated the role of ATP-sensitive (K-ATP) and Ca2+- activated K+ currents (small...

KATP channel mediation of anoxia-induced outward current in rat dorsal vagal neurons in vitro.

Trapp, S, Ballanyi, K

1. Thin brainstem slices (150 microns thickness) were taken from mature rats, and membrane potentials (Em) and currents (Im) in the dorsal vagal neurons (DVN) were analysed with whole-cell patch...

Calcium-dependent responses in neurons of the isolated respiratory network of newborn rats.

Onimaru, H, Ballanyi, K, Richter, D W

1. Membrane potentials (Em) and currents (Im) were measured using whole-cell patch clamp techniques in inspiratory (Insp, types I-III), preinspiratory (Pre-I) and tonic expiratory (Exp) neurons of...

Interstitial PCO2 and pH, and their role as chemostimulants in the isolated respiratory network of neonatal rats.

Voipio, J, Ballanyi, K

1. CO2-H(+)-sensitive microelectrodes were used for simultaneous measurements of the partial pressure of CO2 (PCO2) and extracellular pH (pHo) in the ventral respiratory group (VRG) of the isolated...

cAMP-dependent reversal of opioid- and prostaglandin-mediated depression of the isolated respiratory network in newborn rats.

Ballanyi, K, Lalley, P M, Hoch, B, Richter, D W

1. Membrane potential (Vm) and resistance (Rm) of ventral respiratory group (VRG) neurons were measured in the isolated brainstem-spinal cord from newborn rats during bath application of the opioid...

Membrane potentials and microenvironment of rat dorsal vagal cells in vitro during energy depletion.

Ballanyi, K, Doutheil, J, Brockhaus, J

1. Brainstem slices were taken from mature rats. In the dorsal vagal nucleus (DVNX), membrane potentials (Em) of neurons (DVNs) and glia, as well as extracellular oxygen, K+ and pH (Po2, aKo, pHo),...

Acidosis of rat dorsal vagal neurons in situ during spontaneous and evoked activity.

Trapp, S, Lückermann, M, Brooks, P A, Ballanyi, K

1. Rat brainstem slices were taken for simultaneous measurements of intracellular pH (pHi) and membrane currents or potentials in dorsal vagal neurons, dialysed with the pH-sensitive dye BCECF. 2....

Microenvironment of respiratory neurons in the in vitro brainstem-spinal cord of neonatal rats.

Brockhaus, J, Ballanyi, K, Smith, J C, Richter, D W
