Spindle - Swedish translation, definition, meaning, synonyms, pronunciation, The neocortex of many cetaceans is home to elongated spindle neurons that,

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.

tapping the knee tendon stretches the muscle and pulls on the muscle spindle receptor. This sensory information is conveyed to the CNS, to the motor neurons

Rare spindle-shaped neurons from deep inside the brain recorded for the first time Losing the mysterious cells may lead to Alzheimer’s, schizophrenia, or other neurological disorders 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 or Von Economo neurons (VENs) are bipolar neurons in the anterior cingulate, frontoinsular, and dorsoloteral prefrontal cortices of great apes (humans, gorillas, chimpanzees, bonobos, and orangutans), and while previously thought to be unique to the great apes, have more recently been found in cetaceans (humpback, fin, killer, and sperm whales) [8]. 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. The firing of gamma motor neurons in sync with alpha motor neurons pulls muscle spindles from polar ends of the fibers as this is where gamma motor neurons innervate the muscle. The spindle is innervated by type Ia sensory fiber that go on to synapse with alpha motor neurons, completing the gamma-loop. A spindle ending is located at the end of a neuron or an axon whose body is in the spinal ganglion .

These fibres are important in signalling the length and velocity of a muscle. The function of γ-motor neurons is to keep the fibre taut by causing contraction of its polar ends.

Patterned neuronal activity such as spindle bursts in the neonatal cortex is likely to promote the maturation of cortical synapses and neuronal circuits. Previous work on cats has shown that removal of subplate neurons, a transient neuronal population in the immature cortex, prevents the functional maturation of thalamocortical and intracortical connectivity.
