Randomly came across your video. You should definitely start teaching. Good one!

This makes more sense than two hours of my professor trying to explain the same topic 😅

really good. it helped me a lot, thanks!!

why does the early current first increase and then decrease with increasing depolarization while the late current only increases?

Arpan very nicely explained. I enjoyed. I am just wondering why we inject negative current to measure input resistance in a muscle or neuron. I am thinking about this for a while. Thank you

Sir please make some more videos about the Nmr spectroscopy

Very interesting topic. What effects on physiology would high and low resistance neurons have? For example, what effects will it have? Effects on reaction times perhaps? On energy metabolism? And how? Are there ways to change the input resistance by perhaps changing the channels for ion flows? And how? Please give more details. Also please explain a bit more on how the neuron capacitor part discharges through the load resistor while maintaining continuity of current flow. What provides the potential difference across it to charge the capacitor in the parallel RC set up, what comprises the capacitance and resistance, can we compute and change their values, and what physiological effects will this have?

Sir, could you please explain why HCN channels on dendritic spikes of pyramidal cells (in prefrontal cortex) reduce membrane resistance? To my knowledge, HCN channels mediate inward Na, K current - that should depolarise the neuron and that should facilitate nerve conduction, right?
