Pain Flashcards
Nociception and pain
• Nociception is the sensing of stimuli that are potentially harmful to the body.
the neuronal basis of pain
Recordings from nociceptors and non-nociceptive thermoreceptors
____________________ respond to a wide range of stimuli while the___________________ respond to temps that are more noxious
Thermoreceptors, nociceptors
Pain circuit
• Nociceptors in the thumb/skin
synaptic plasticity in pain
• Occurs in pain circuits
Postsynaptic mechanisms of synaptic plasticity
• Changes important for LTP which is important in pain sensivity; increase/decrease
Presyantic mechanisms of synaptic plasticity
Presyanptic mechanisms of synaptic plasticity
activity dependent presyantic plasticity at nociceptive synapse
Structural changes occur
activity dependent postsynaptic plasticity at nociceptive synapse
• Post synaptic side
Microglia-neuron interactions in the spinal cord are crucial to pain hypersensitivity induced by peripheral-nerve injury
• In mice lookin at how injury can induce increase in pain sensitivity
Sex differences and pain
• Experiment done on males and females
why does pain sensitivity differ in males and females
• Injury induced leads to BDNF released …….has effects on NMDA receptors ….inhibiting KCC2 increasing pain
Social communications and pain
• Studies on mice
Human and animal models of nociception and pain
• Advantages and disadvantage when looking at diff models
Nociceptors in drosophila are analogous to nociceptors in _______________
Mammals
