| Question | Answer |
| Homosynaptic facilitation | increase in response in one post-synapse due to stimulation of one pre-synpase |
| Heterosynaptic facilitation | enhanced response in a post-synapse due to interaction between a few pre-synapses |
| Windup/ homosynaptic potentiation | a progressively increasing output during the course of a train of identical stimuli (technically called homosynaptic potentiation) |
| Pain matrix | a network of cortical areas through which pain is generated from nociception |
| Myofascial trigger point | also known as trigger sites or muscle knots, are described as hyperirritable spots in skeletal muscle |
| Event-related magnetic field (ERP) | Magnetic field recorded from EEG in response to a stimulus |
| The salience of a given stimulus | is defined as its ability to stand out relative to neighboring stimuli |
| peripersonal space | a representation of the body and environment within grasp |
| Hyperalgesia | An increased response to a stimulus which is normally painful. |
| Define pain | An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. |
| Noxious stimulus | damaging to normal tissues |
| Nociceptor | A receptor that detects and transduces a potentially injurious stimulus and/or a primary sensory neuron that is preferentially sensitive to a noxious stimulus. |
| Allodynia | Pain due to a stimulus which does not normally provoke pain. |
| Neuropathic Pain | Pain initiated or caused by a primary lesion or dysfunction in the nervous system. |
| Peripheral Neuropathic Pain | Pain initiated or caused by a primary lesion or dysfunction in the peripheral nervous system. |
| central sensitization | refers to an increased sensitivity to pain in the central nervous system |
| perirhipheral sensitization | a state of heightened sensitivity in which the threshold of activation of transducer receptors such as TRPV1 is reduced, and the excitability of the peripheral terminal membrane increases. |
