Kv3 K+ currents contribute to spike-timing in dorsal cochlear nucleus principal cells
Exposure to loud sound increases burst-firing of dorsal cochlear nucleus (DCN) fusiform cells in the auditory brainstem, which has been suggested to be an electrophysiological correlate of tinnitus. The altered activity of DCN fusiform cells may be due to down-regulation of high voltage-activated (Kv3-like) K+ currents. Whole cell current-clamp recordings were obtained from DCN fusiform cells i...
متن کاملModel of auditory prediction in the dorsal cochlear nucleus via spike-timing dependent plasticity
This study investigates the learning dynamics of cartwheel cells in the dorsal cochlear nucleus (DCN). Cartwheel cells are excited by parallel fibers that carry information from various sources, such as auditory stimuli, proprioception and recurrent inputs from higherorder auditory processing. Thus, these cells are thought to be involved in multimodal sensory integration. Extracellular in vivo ...
متن کاملSynaptic inputs to granule cells of the dorsal cochlear nucleus.
The mammalian dorsal cochlear nucleus (DCN) integrates auditory nerve input with nonauditory signals via a cerebellar-like granule cell circuit. Although granule cells carry nonauditory information to the DCN, almost nothing is known about their physiology. Here we describe electrophysiological features of synaptic inputs to granule cells in the DCN by in vitro patch-clamp recordings from P12 t...
متن کاملAction potential timing precision in dorsal cochlear nucleus pyramidal cells.
Many studies of the dorsal cochlear nucleus (DCN) have focused on the representation of acoustic stimuli in terms of average firing rate. However, recent studies have emphasized the role of spike timing in information encoding. We sought to ascertain whether DCN pyramidal cells might employ similar strategies and to what extent intrinsic excitability regulates spike timing. Gaussian distributed...
متن کاملSomatosensory effects on neurons in dorsal cochlear nucleus.
1. Single units and evoked potentials were recorded in dorsal cochlear nucleus (DCN) in response to electrical stimulation of the somatosensory dorsal column and spinal trigeminal nuclei (together called MSN for medullary somatosensory nuclei) and for tactile somatosensory stimuli. Recordings were from paralyzed decerebrate cats. 2. DCN principal cells (type IV units) were strongly inhibited by...
