I have some pretty cool news to share-I’m officially a published PRF (Pain Research Forum) author!
Below is the link to the news article I wrote on Crook’s 2021 study: “Behavioral and neurophysiological evidence suggests affective pain experience in octopus.”

This summer (2021), I am leading a Journal Club for Dr. Nathan Fried’s neuroscience of chronic pain lab. I gave an example presentation at the beginning of the summer, and chose to do the article that I had written a news article for PRF for. Below, I have included some of the slides from my journal club presentation of Crook’s 2021 study: “Behavioral and neurophysiological evidence suggests affective pain experience in octopus”.
Key Terms:
| Nociceptors: | sensory receptors for painful stimuli | |||
| Peripheral Nervous System: | includes all the nerves outside the central nervous system | |||
| Peripheral Sensitization | decreased threshold response of the sensory nerve fibers in the peripheral to external stimulus | |||
| Spontaneous Activity | automatic firing of neurons, or firing in the absence of observable stimuli 1 | |||
| Nociceptive Sensitization | a non-associative learning process in which repeated administration of a noxious stimulus results in the progressive amplification of a pain-related response |
