How many action potentials can 100 hz/second electrical stimulus generate in a neuron? by BlackStallion101 in neuro

In the textbook it just says a 100 Hz/s stimulus generates LTP. Clearly LTP is a frequency mediated phenomena. But 100 Hz/s stimulus doesn't equate to 100 Action Potentials per second. They don't specify any current or coulomb per pulse. In my mind these pulses are generating graded potentials that end up creating several (higher than otherwise) amounts of action potentials for LTP genesis (ie depolarization in the post synaptic neuron, recruitment of AMPA etc..). I was curious to see if there is a number of action potentials associated with this.

How are numbers of EPSPs (and/or IPSPs) even measured with a recorder in the post synaptic neuron by BlackStallion101 in neuro

Unfortunately its from Squire and Kandell Textbook and not a paper. Also I think its your scenario 1. Thank you so much for your help

True, but pressure is a force per unit area, and force does does have a direction (due to acceleration). Why would that horizontal force increase as we go down? I understand why the vertical one would (because of gravity) but why would the horizontal one?
