Interneurons and relay neurons
WebAccurate motor performance depends on the integration in spinal microcircuits of sensory feedback information. Hand grasp is a skilled motor behavior known to require cutaneous sensory feedback, but spinal microcircuits that process and relay this feedback to the motor system have not been defined. We sought to define classes of spinal interneurons … WebInterneurons (also known as relay neurons) are fully contained in the central nervous system (the spinal cord and the brain). The interneuron serves as the connection between the sensory neurons and the motor neurons. The …
Interneurons and relay neurons
Did you know?
Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect to brain regions, i.e. not direct 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). They play vital roles in reflexes, neuronal oscillations, and neurogenesis in the ad… WebOct 7, 2024 · Neurotransmitter heterogeneity of dorsal horn neurons. Fluorescent in situ hybridization labelling for VGLUT2 (magenta), GAD1 (green), and VGAT (white) shows excitatory interneurons (magenta) outnumber inhibitory interneurons (green and white, or white only) in laminae I–III.
