Dendritic spine - Wikipedia
网页A dendritic spine (or spine) is a small membrane protrusion from a neuron's dendrite that typically receives input from a single axon at the synapse. Dendritic spines serve as a storage site for synaptic strength and help transmit electrical signals …

Dendritic spines: from structure to in vivo function - PMC
网页2012年7月13日 · Dendritic spines arise as small protrusions from the dendritic shaft of various types of neuron and receive inputs from excitatory axons. Ever since dendritic spines were first described in the nineteenth century, questions about their function have spawned many hypotheses.
网页Dendritic spines are tiny protrusions that receive excitatory synaptic input and compartmentalize postsynaptic responses. Heterogeneous in size and shape, and modifiable by...
Dendritic Spine Plasticity: Function and Mechanisms - PMC
网页2020年8月28日 · Dendritic spines are small protrusions studding neuronal dendrites, first described in 1888 by Ramón y Cajal using his famous Golgi stainings. Around 50 years later the advance of electron microscopy (EM) confirmed Cajal’s intuition that spines constitute the postsynaptic site of most excitatory synapses in …
Introduction: What Are Dendritic Spines? | SpringerLink
网页Dendritic spines are cellular specializations that greatly increase the connectivity of neurons and modulate the “weight” of most postsynaptic excitatory potentials. Spines are found in very diverse animal species providing neural networks with a high...
Dendritic Spine - an overview | ScienceDirect Topics
网页A dendritic spine refers to the major postsynaptic site of glutamatergic synapses in the brain that plays a crucial role in synaptogenesis, synaptic regulation, and cognition. It is a small protrusion on the dendrites of neurons that undergoes changes and deficits associated with various physiological and pathological conditions.
