Dendritic Spikes in Sensory Perception
What is the function of dendritic spikes? One might argue that they provide conditions for neuronal plasticity or that they are essential for neural computation. However, despite a long history of dendritic research, the physiological relevance of dendritic spikes in brain function remains unknown. This could stem from the fact that most studies on dendrites have been performed in vitro. Fortun...
متن کاملDendritic Spikes Veto Inhibition
How inhibition regulates dendritic excitability is critical to an understanding of the way neurons integrate the many thousands of synaptic inputs they receive. In this issue of Neuron, Müller et al. (2012) show that inhibition blocks the generation of weak dendritic spikes, leaving strong dendritic spikes intact.
متن کاملAntidromic Spikes in Olfactory Sensory Neurons
Spikes were evoked in rat olfactory sensory neuron (OSN) populations by electrical stimulation of the olfactory bulb nerve layer in pentobarbital anesthetized rats. The latencies and recording positions for these compound spikes showed that they originated in olfactory epithelium. Dual simultaneous recordings indicated conduction velocities in the C-fiber range, around 0.5 m/sec. These spikes a...
متن کاملExtrasomatic spikes recorded from cat motoneurons. Possible dendritic spikes.
Extrasomatic (ES-) spikes were recorded in motoneurons in cats anesthetized with pentobarbital sodium and immobilized with d-tubocurarine. ES-spikes, 40-79 mV in amplitude, were distinguished from intrasomatic spikes by their differences in responses to a train of 8 pulses at 500 Hz given to the L 7 or S 1 ventral root. In 23 motoneurons 3-6 different spikes could be recorded from the same site...
متن کاملDendritic initiation and propagation of spikes and spike bursts in a multimodal sensory interneuron: the crustacean parasol cell.
Invasion of dendrites by spikes and spike bursts can play a critical role in regulating the output of central neurons by modifying their dynamic input-output relationships. Back-propagating bursts can modulate voltage-gated channels in the short term and can also modify long-term responses to synaptic input. Determining the morphological site of spike initiation and the mode of propagation thro...
