Excitatory EPSP takes place if the reversal potential is more positive than threshold.Group of answer choicesTrueFalse

Excitatory postsynaptic potentials (EPSPs) move the membrane potential threshold. Inhibitory postsynaptic potentials (IPSPs) move the membrane potential threshold.

An excitatory postsynaptic potential (EPSP) occurs when neurotransmitters bind to their receptors and open chemically-gated ______ channels.Multiple choice question.sodiumpotassiumcalciummagnesium

If both IPSP's and EPSP's stimulate the same postsynaptic cell, which of the following is true?   Multiple choice question.The postsynaptic cell will likely never fire because of the conflicting input.The response of the postsynaptic cell depends on which type of graded potential has a larger effect.Only one of the stimulus types determines the effect in the postsynaptic cell

Which statement about EPSPs in the central nervous system is true?Group of answer choicesThey are much larger than end plate potentials.the istance between inputs does not affect the ability of EPSPs to summatethe time between inputs does not affect the ability of EPSPs to summateTheir effect in the central nervous system can be nullified by IPSPs.They can be hyperpolarizing.

An ______ postsynaptic potential involves the opening of sodium channels, depolarizing the membrane, and bringing it closer to a threshold level.Multiple choice question.excitatoryinhibitory
