  • stimuli
  • Although a continuously varying membrane potential contains more information than binary spike trains, we find situations where different stimuli can be better discriminated on the basis of spike responses than on the basis of graded responses. (uni-oldenburg.de)
  • temporal
  • Although a tight temporal coupling between pre- and postsynaptic spikes exists, the timing between these spikes is also affected by graded potential changes. (wiley.com)
  • To appreciate how spontaneous activity shapes cortical circuits, it is essential to understand how the spatial and temporal correlational structure of ongoing activity changes in the intact developing neocortex. (jneurosci.org)
  • Model outputs also satisfied criteria characteristic of electrical syncytia such as correlation between the spatial spread and temporal decay of electrotonic potentials as well as positively skewed amplitude frequency histogram for sub-threshold potentials, and lead to interesting conclusions.

  • dendrites
  • The relative magnitude of the transport number effect within the invaginations (or dendrites) and other transport number contributions to slow potential changes have also been assessed and order-of-magnitude values of these are estimated for some biological data. (springer.com)
  • spatial
  • The first method, patch-clamp electrophysiology, uses a single electrode to make contact with or puncture a cell to record changes in membrane potential, sacrificing throughput and spatial resolution to achieve a comprehensive description of a single cellular electrophysiological profile. (pnas.org)
  • protein
  • Activation of these and other signaling pathways in turn leads to changes in gene expression and protein synthesis of important regulatory mechanisms controlling tissue structure and function, e.g. (rupress.org)
  • responses
  • 1. The membrane responses of rabbit papillary muscles to rapid changes in [K](o) and [Cl](o) were measured with open-tipped micropipettes and with closed micropipettes made from K-selective glass.2. (biomedsearch.com)
  • signals
  • Binding of these substances to specific receptors embedded in the postsynaptic membrane can exert either electrical or biochemical signals by stimulation of ionotropic or metabotropic receptors, respectively. (fz-juelich.de)
  • effect
  • The effect of colonisation by arbuscular mycorrhizal (AM) fungi on the relationship between phosphorus (P) uptake and root membrane electric potential difference (p.d.) was investigated in leek (Allium porrum L.). Plants were grown, with or without the AM fungus Scutellospora calospora (Nicolson and Gerdemann) Walker and Sanders, in soil. (edu.au)
