Equilibrium of the body ~ Vestibular system (Part 1)  

Ooh. That's quite a question. Similarities?? I mean, many differences come to mind instantly. Like, organ of corti is for pressure transduction ; olfactory is for chemo-transduction. (Let me just think about differences. This i am just replying instantly.)

@@VivekSirsPhysiology exactly, i also get differences in my mins when i think of similarities

@@Stubborn214 Let me just think a little bit. May be, if there are some…….

@@VivekSirsPhysiology sir u may take the question as “similarities bw olfactory epithelium and organ of corti”

@@Stubborn214 but still…..organ of corti is a receptor organ; olfactory epithelium is …an epithelium. Anyway, let’s figure out this riddle.

Thanks

Welcome..! Hope it helped.

@@VivekSirsPhysiology alot as always🙌🏿

Information processing by the brain/higher centers does not necessarily require APs generated (newly) from some peripheral source and reaching cortex. Even when head is still, the APs do originate from hair cells and reach higher centers and cortex. This detects the orientation of head, when head is still. Change in this signal, in the form of hyperpolarization of hair cells, and decreased frequency of APs is processed by the cortex as the change in the orientation of head. Same principle also applies to rods in the retina. When light strikes retina, rods are hyperpolarized and AP frequency in optic nerve decreases, which is sensed as the light sensation.

That means here is another example apart from retina where information is carried through hyperpolarization. Or we can say decreased AP

@@physiologyconceptsbydrsabi9170 yes. Correct. We generally believe that the APs carry the information. That’s partly correct. However, increased or decreased AP frequencies, and the processing of this by higher centers is of critical importance.

Didn’t understand. Which PPT?

Yes. Coming up the next part of this video in some time.

Ok. Check out the group. Posted the PDF over there.
