Chapter 41, Problem 9TYU

(a)

Summary Introduction

To determine: Whether the “Influx of ${\text{Na}}^{+}$ ions inside the membrane of post synaptic neuron” will cause excitatory postsynaptic potential (EPSP) or inhibitory postsynaptic potential (IPSP).

Introduction: Signal transduction in neurons depends upon the resting potential of the membrane of the neuron. Signals are sent by a wave of depolarization. This wave of polarization develops only when depolarization potential is more than the threshold potential. This potential is termed as action potential of the membrane.

(b)

Summary Introduction

To determine: Whether the “${\text{K}}^{+}$ diffusion towards outside of membrane of post synaptic neuron” will cause excitatory postsynaptic potential (EPSP) or inhibitory postsynaptic potential (IPSP).

Introduction: Signal transduction in neurons depends upon the resting potential of the membrane of the neuron. Signals are sent by a wave of depolarization. This wave of polarization develops only when depolarization potential is more than the threshold potential. This potential is termed as action potential of the membrane.
