  • synapses
  • In contrast to the enormous progress made in mapping out postsynaptic contributions of receptors, scaffolding structures and receptor trafficking to synaptic transmission and plasticity, the small size of nerve terminals has largely precluded direct analyses of presynaptic modulation of excitability and transmitter release in central synapses.

  • currents
  • This review will highlight experimental evidence that resolves several long-standing issues with respect to intricate interplays between the waveform of action potentials, Ca 2+ currents and transmitter release and further conceptualize their relationships in a physiological context with theoretical models of the spatial organization of voltage-gated Ca 2+ channels and synaptic vesicles at release sites.

  • action
  • Electric pulses or action potentials (APs or spikes) are initiated near the soma of presynaptic neurons and propagated along the axon to the nerve terminal where voltage-gated Ca 2+ channels (VGCCs) open and transiently raise intracellular Ca 2+ concentration. (biomedcentral.com)
  • stages
  • Finally, we report a preliminary investigation into the use of multifractal detrended fluctuation analysis as a pattern classification technique on human EEG signals from waking and different sleep stages, and demonstrate its potential utility for automatic classification of different states of consciousness.

  • effects
  • To distinguish between these forms of MI we employed an event related potential (ERP) study to measure interference effects induced by hand orientation manipulations in a hand laterality judgement task. (jove.com)
  • brain
  • a macroscopic model of brain dynamics could be built on existing measurement techniques, such as the local-field potential (LFP). (jneurosci.org)
  • To better understand cognitive processes, it is thus advantageous to utilize event-related potential (ERP) recording as a method of gathering information about the brain. (jove.com)
