Neuromatrix
Neuromatrix
The Neuromatrix (pronounced: /ˈnʊəroʊˈmeɪtrɪks/), also known as the Neurological Matrix, is a theoretical framework proposed by Melzack in 1989 to explain the multidimensional nature of pain perception. The concept is rooted in the field of Neuroscience and Pain Management.
Etymology
The term 'Neuromatrix' is derived from the Greek words 'neuron' meaning nerve and 'matrix' meaning womb or origin. It signifies the network of neurons in the brain that generates the perception of pain.
Definition
The Neuromatrix is defined as a network of neurons in the brain that integrates multiple sources of information to generate the perception of pain. It includes areas involved in sensory, emotional, and cognitive processing. The Neuromatrix theory suggests that pain is not solely a response to peripheral nociceptive input but is also influenced by cognitive and emotional factors.
