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

Hyperpolarization of a postsynaptic neuron in response to a neurotransmitter is called an Blank______ postsynaptic potential.Multiple choice question.excitatoryinhibitory

Inhibitory postsynaptic potentials involve Blank______ of the plasma membrane.Multiple choice question.depolarizationhyperpolarization

Inhibitory postsynaptic potentials are due to the opening of Blank______ channels.Multiple select question.sodiumchloridecalciumpotassium

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

Graded membrane potentials:Help determine whether a neuron will reach thresholdRely heavily on voltage gated ion channelsAre excitatory when they make membrane potential more negativeAre excitatory when they hyperpolarise the cell
