    Notes: Summary Physiological and morphological properties of rabbit, Oryctolagus cuniculus, olfactory bulb interneurons were characterized by using a thin slice preparation in combination with patch-clamp measurements and Lucifer Yellow fills. Two types of interneurons, periglomerular (PG) and juxtaglomerular (JG) cells, were unequivocally distinguished in the glomerular layer. Their properties were compared to those of mitral cells. PG cells closely resembled previously described periglomerular cells in their morphology. During current clamp recording these neurons were characterized by their lack of action potentials upon depolarization. Consistent with these results no Na+ currents could be elicited in voltage clamp experiments. Two types of outward K+ currents were distinguished: one which inactivated and one which did not. From their morphology JG cells appear to be either short axon cells or external tufted cells. JG cells always responded with a single, TTX-blockable action potential in response to maintained current injection. Two types of membrane currents were identified in JG cells during voltage clamp: a fast, inactivating Na+ current that was fully activated at — 80 mV, and a sustained outward current that shared some properties with a delayed rectifier K+ current. The particular relationship between the voltage dependence of the Na+ and K+ currents appeared to preclude repetitive spike activity.

    Description: Author(s): Benjamin Stadtmüller, Norman Haag, Johannes Seidel, Gerben van Straaten, Markus Franke, Christian Kumpf, Mirko Cinchetti, and Martin Aeschlimann The understanding of the fundamental geometric and electronic properties of metal-organic hybrid interfaces is a key issue on the way to improving the performance of organic electronic and spintronic devices. Here, we studied the adsorption heights of copper-II-phthalocyanine (CuPc) and 3,4,9,10-per… [Phys. Rev. B 94, 235436] Published Tue Dec 27, 2016
