Golgi I
Encyclopedia
A Golgi I or Golgi type I neuron
is a neuron which has a long axon
that begins in the grey matter
of the central nervous system
and may extend from there. Golgi II
neurons, in contrast, are defined as having short axons or no axon at all. This distinction was introduced by the pioneering neuroanatomist Camillo Golgi
, on the basis of the appearance under a microscope of neurons stained with the Golgi stain that he had invented. Santiago Ramón y Cajal
postulated that higher developed animals had more Golgi type II cells
in comparison to Golgi type I neurons.
Neuron
A neuron is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. Chemical signaling occurs via synapses, specialized connections with other cells. Neurons connect to each other to form networks. Neurons are the core components of the nervous...

Axon
An axon is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body or soma....

Grey matter
Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil , glial cells and capillaries. Grey matter contains neural cell bodies, in contrast to white matter, which does not and mostly contains myelinated axon tracts...

Central nervous system
The central nervous system is the part of the nervous system that integrates the information that it receives from, and coordinates the activity of, all parts of the bodies of bilaterian animals—that is, all multicellular animals except sponges and radially symmetric animals such as jellyfish...

Golgi II
A Golgi II or Golgi type II neuron is a neuron having either no axon or else a short axon that does not send branches out of the gray matter of the central nervous system.-External links:* via the Neuroscience Information Framework...

Camillo Golgi
Camillo Golgi was an Italian physician, pathologist, scientist, and Nobel laureate.-Biography:Camillo Golgi was born in the village of Corteno, Lombardy, then part of the Austrian Empire. The village is now named Corteno Golgi in his honour. His father was a physician and district medical officer...

Santiago Ramón y Cajal ForMemRS was a Spanish pathologist, histologist, neuroscientist, and Nobel laureate. His pioneering investigations of the microscopic structure of the brain were original: he is considered by many to be the father of modern neuroscience...
