متن کاملFrom periodic travelling waves to travelling fronts in the spike-diffuse-spike model of dendritic waves.
In the vertebrate brain excitatory synaptic contacts typically occur on the tiny evaginations of neuron dendritic surface known as dendritic spines. There is clear evidence that spine heads are endowed with voltage-dependent excitable channels and that action potentials invade spines. Computational models are being increasingly used to gain insight into the functional significance of a spine wi...
متن کاملNMDA receptor-mediated Na+ signals in spines and dendrites.
Spines and dendrites of central neurons represent an important site of synaptic signaling and integration. Here we identify a new, synaptically mediated spine signal with unique properties. Using two-photon Na(+) imaging, we show that suprathreshold synaptic stimulation leads to transient increases in Na(+) concentration in postsynaptic spines and their adjacent dendrites. This local signal is ...
متن کاملMode Locking in a Spatially Extended Neuron Model: Active Soma and Compartmental Tree
Understanding the mode-locked response of excitable systems to periodic forcing has important applications in neuroscience. For example it is known that spatially extended place cells in the hippocampus are driven by the theta rhythm to generate a code conveying information about spatial location. Thus it is important to explore the role of neuronal dendrites in generating the response to perio...
متن کاملDendritic cable with active spines: A modelling study in the spike-diffuse-spike framework
The spike-diffuse-spike (SDS) model describes a passive dendritic tree with active dendritic spines. Spine-head dynamics is modelled with a simple integrate-and-fire process, whilst communication between spines is mediated by the cable equation. Here we develop a computational framework that allows the study of multiple spiking events in a network of such spines embedded in a simple one-dimensi...
