A glass tube was inserted into the axon and the movement of the air\u2010water interface formed on the end of the tube was observed with a Y\u2010shaped fibrescope. The intracellular pressure increased and decreased rapidly when an action potential was induced by electrical stimulation. The amplitude of the response was about 10 mPa (or 1 X 10(\u20103) mmH2O), which was very large in comparison with that observed in unperfused axons. It was sensitive to extracellular Ca2+. The pressure response appeared in an all\u2010or\u2010none manner and could be suppressed by tetrodotoxin. This excluded physicochemical processes on the stimulating electrode or current\u2010supplying electrode as sources of the response. Various other sources of artifacts were also excluded. An extensive removal of the axoplasm by intracellular perfusion with a protease\u2010containing solution and a KCl solution did not eliminate the pressure response. The intracellular pressure was membrane potential dependent, increasing upon depolarization and decreasing upon hyperpolarization of the membrane. Under voltage clamp, the relationship between the membrane potential and the pressure response was parabolic with a maximum at +109 mV (in reference to the resting level). The response did not depend on the membrane current. A much slower response due to electro\u2010osmotic water flow was also detected. The pressure response induced by hyperpolarization of the membrane was suppressed by extracellular application of a lidocaine\u2010containing solution, but not by a tetrodotoxin\u2010containing solution. These results suggest that the pressure responses arise either from a change in electrostriction across the axolemma or from a change in charge\u2010dependent tension along the axolemma.<\/jats:p>","DOI":"10.1113\/jphysiol.1985.sp015898","type":"journal-article","created":{"date-parts":[[2014,12,19]],"date-time":"2014-12-19T06:45:33Z","timestamp":1418971533000},"page":"229-248","source":"Crossref","is-referenced-by-count":48,"title":["Potential\u2010dependent variations of the intracellular pressure in the intracellularly perfused squid giant axon."],"prefix":"10.1113","volume":"369","author":[{"given":"S","family":"Terakawa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1985,12]]},"container-title":["The Journal of Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1113%2Fjphysiol.1985.sp015898","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/physoc.onlinelibrary.wiley.com\/doi\/pdf\/10.1113\/jphysiol.1985.sp015898","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T15:42:35Z","timestamp":1697816555000},"score":1,"resource":{"primary":{"URL":"https:\/\/physoc.onlinelibrary.wiley.com\/doi\/10.1113\/jphysiol.1985.sp015898"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1985,12]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1985,12]]}},"alternative-id":["10.1113\/jphysiol.1985.sp015898"],"URL":"https:\/\/doi.org\/10.1113\/jphysiol.1985.sp015898","archive":["Portico"],"relation":{},"ISSN":["0022-3751","1469-7793"],"issn-type":[{"value":"0022-3751","type":"print"},{"value":"1469-7793","type":"electronic"}],"subject":[],"published":{"date-parts":[[1985,12]]}}}
