Abolition of spindle oscillations in thalamic neurons disconnected from nucleus reticularis thalami. Steriade M, Deschênes M, Domich L, Mulle C. The effects of depriving thalamic relay and intralaminar nuclei from their reticularis thalami (RE) inputs were investigated in acute and chronic experiments on cat.

Spindle neurons, also called von Economo neurons (VENs), are a specific class of neurons that are characterized by a large spindle-shaped soma, gradually tapering into a single apical axon in one direction, with only a single dendrite facing opposite.

Whereas other types of cells tend to have many dendrites, the polar shaped morphology of spindle neurons is unique. Spindle neurons, also called von Economo neurons (VENs), are a specific class of neurons that are characterized by a large spindle-shaped soma (or body), gradually tapering into a single apical axon in one direction, with only a single dendrite facing opposite. Other neurons tend to have many dendrites, and the polar-shaped morphology of spindle neurons is unique.

These neurons also play a role muscle spindles to changes in length also play an important role in regulating the The discovery of spindle neurons in diverse whale species[3][4] has led to the suggestion that they are "a possible obligatory neuronal adaptation in very large brains, permitting fast information processing and transfer along highly specific projections and that evolved in relation to emerging social behaviors."[4]p. 254 Their presence in the brains of these species supports this theory Spindle neuron: A large neuron tapered at both ends that is only found in humans and great apes and so is thought to be a relatively recent evolutionary addition to the nervous system.

(The efferents that innervate extrafusal fibers are known as alpha motor neurons). The role of the gamma MN is to maintain muscle spindle tapping the knee tendon stretches the muscle and pulls on the muscle spindle receptor.

1). Spindle neurons are restricted to the subfields of the anterior cingulate cortex (Brodmann's area 24), exhibiting a greater density in anterior portions of this area than in posterior portions, and tapering off in the transition zone between anterior and posterior cingulate cortex. VENs are large, spindle-shaped neurons. They were first identified by the Ukrainian scientist Vladimir Betz more than a century ago. They were later named after the anatomist Constantin von Economo, who described their shape and distribution through the human cortex. The spindle-shaped brain cells you refer to are called von Economo neurons —named after the man who first described them (source: Smithsonian)..
