Webb19 maj 2024 · Gate control theory suggests that the spinal cord contains a neurological 'gate' that either blocks pain signals or allows them to continue on to the brain. This theory is often used to explain both phantom and chronic pain issues . Unlike an actual gate, which opens and closes to allow all things to pass through, the gate in the spinal cord ...

WebbPain Processes. Figure 7-1 illustrates the major components of the brain systems involved in processing pain-related information. There are four major processes: transduction, transmission, modulation, and perception. Transduction refers to the processes by which tissue-damaging stimuli activate nerve endings. WebbNeurotransmission (Latin: transmissio "passage, crossing" from transmittere "send, let through") is the process by which signaling molecules called neurotransmitters are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and react with the receptors on the dendrites of another neuron (the postsynaptic neuron) a ...
