One is that sensory input is appropriately routed to different CPG neurons as a function of motor pattern phase. The other is that the input reaches the same neurons at all phases, but that, as a consequence of the way in which the network transforms the input, network response varies appropriately as a function of motor pattern phase."

Central pattern generators are groups of neurons in the spinal cord that are responsible for generating stereotyped movement. It has been shown that in cats, rhythmic activation patterns are still observed following removal of sensory afferents and removal of the brain., [1] indicating that there is neural pattern generation in the spinal cord independent of descending signals from the brain ...
With their flask-shaped cell bodies, many branching dendrites, and a single long axon, these cells are essential for controlling motor activity. Purkinje cells mainly release GABA (gamma-aminobutyric acid) neurotransmitter, which inhibits some neurons to reduce nerve impulse transmission. Purkinje cells efficiently control and coordinate the ...
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways , and parts of the brain involved in sensory perception and interoception .
For example, in fruit flies, specific multidendritic sensory neurons play a role in nociception. [22] In mollusks, nociceptive responses are mediated by pedal sensory neurons. [ 23 ] [ 24 ] Crustaceans, on the other hand, utilize a variety of sensory cell types, including chordotonal organs and mechanoreceptors, to detect potentially damaging ...
Spinal neurons are specialized nerve cells located within the spinal cord. [1] They are a crucial component of the central nervous system.These neurons play vital roles in transmitting and processing information between the brain and the rest of the body.
A spinal interneuron, found in the spinal cord, relays signals between (afferent) sensory neurons, and (efferent) motor neurons. Different classes of spinal interneurons are involved in the process of sensory-motor integration. [1] Most interneurons are found in the grey column, a region of grey matter in the spinal cord.
Interneurons (also called internuncial neurons, association neurons, connector neurons, or intermediate neurons) are neurons that are not specifically motor neurons or sensory neurons. Interneurons are the central nodes of neural circuits , enabling communication between sensory or motor neurons and the central nervous system (CNS). [ 2 ]
