Attenuation of Synaptic Potentials in Dendritic Spines [PDF]
Summary: Dendritic spines receive the majority of excitatory inputs in many mammalian neurons, but their biophysical properties and exact role in dendritic integration are still unclear.

Electrical advantages of dendritic spines. [PDF]
Many neurons receive excitatory glutamatergic input almost exclusively onto dendritic spines. In the absence of spines, the amplitudes and kinetics of excitatory postsynaptic potentials (EPSPs) at the site of synaptic input are highly variable and depend

Structure and Function of Dendritic Spines
▪ Abstract Spines are neuronal protrusions, each of which receives input typically from one excitatory synapse. They contain neurotransmitter receptors, organelles, and signaling systems essential for synaptic function and plasticity. Numerous brain disorders are associated with abnormal dendritic spines.

A spike-timing-dependent plasticity rule for dendritic spines
The structural organization of excitatory inputs supporting spike-timing-dependent plasticity (STDP) in dendritic spines remains unknown. Using a spine STDP protocol, the authors uncover the STDP rules for single, clustered and distributed dendritic ...

Superresolving Dendritic Spines [PDF]
Spines are tiny protrusions that densely stud the dendrites of neurons in the brain. Individual spines are the primary recipients of synaptic inputs from single axons, which emanate from other neurons in the central nervous system. A dendritic tree on one neuron may have hundreds of thousands of spines, making connections to a corresponding number of ...

Signaling in dendritic spines and spine microdomains [PDF]
The specialized morphology of dendritic spines creates an isolated compartment that allows for localized biochemical signaling. Recent studies have revealed complexity in the function of the spine head as a signaling domain and indicate that (1) the spine is functionally subdivided into multiple independent microdomains and (2) not all biochemical ...

Electrical properties of dendritic spines. [PDF]
Dendritic spines are small protrusions that mediate most of the excitatory synaptic transmission in the brain. Initially, the anatomical structure of spines has suggested that they serve as isolated biochemical and electrical compartments. Indeed, following ample experimental evidence, it is now widely accepted that a significant physiological role of ...

Dendritic spines as chemical and electrical compartments : a two-photon imaging study in the hippocampus of the rat [PDF]
Most excitatory synapses are located on small dendritic protrusions called spines. So far, the function of dendritic spines is not fully understood. Imaging experiments have shown that spines can compartmentalize second messengers such as Ca2+.
