Dendrites

Some articles on dendrites, dendrite:

Neural Backpropagation - History
... both through the axon to signal the next neuron and backpropagates through the dendrites sending a retrograde signal to its presynaptic signaling neurons ... This current decays significantly with travel length along the dendrites, so effects are predicted to be more significant for neurons whose synapses are near the postsynaptic cell body, with magnitude depending mainly ... increases the concentration of Ca2+ in the dendrites, an event which coincides with certain models of synaptic plasticity ...
Local Field Potential - Geometrical Arrangement
... In some cells the dendrites face one direction and the soma another, such as the pyramidal cells ... When there is simultaneous activation of the dendrites a strong dipole is produced ... In cells where the dendrites are arranged more radially, the potential difference between individual dendrites and the soma tend to cancel with ...
Dendrite
... Dendrites (from Greek δένδρον déndron, "tree") are the branched projections of a neuron that act to conduct the electrochemical stimulation received from other neural ... Electrical stimulation is transmitted onto dendrites by upstream neurons via synapses which are located at various points throughout the dendritic arbor ... Dendrites play a critical role in integrating these synaptic inputs and in determining the extent to which action potentials are produced by the neuron ...
Apical Dendrite - Pathology - Epilepsy - Infantile Seizures and Associated Memory Impairment
... epilepsy, however, show a reduction in the branching complexity of basal dendrites as well as a decrease in the spine density on both the apical dendrites and the basal dendrites ... of dendritic arbors and a reduction in the branching complexity of the remaining dendrites were observed ... Because dendrites and their spines are sites of excitatory synaptic input onto neurons, the results suggest that the glutaminergic synaptic transmission ...
Dendritic Spine - Development
... During synaptogenesis, dendrites rapidly sprout and retract filopodia, small membrane organelle-lacking membranous protrusions ... However, after this first week, filopodia are replaced by spiny dendrites but also small, stubby spines that protrude from spiny dendrites ... recruit presynaptic contact to the dendrite, which encourages the production of spines to handle specialized postsynaptic contact with the ...
