Question
Chapter 38.6, Problem 2CC
Summary Introduction
To explain:
What if our brain receives more action potentials when our eyes are exposed to light even though our photoreceptors release more neurotransmitter in the dark.
Introduction:
In humans, the vision starts when the photon of the light enters the eye and via pupil and strike the cone and rod cells. The energy of photon shifts the

As stimulus intensity is increased, recording from a single neuron USUALLY shows the amplitude of the action potential increases. the amplitude of the action potential decreases. the amplitude of the action potential may increase or decrease, depending on the stimulus. the rate of firing of the nerve fiber increases. 2. An inhibitory transmitter _______ the firing rate of a neuron and an excitatory transmitter ________ the firing rate. increases; decreases increases; increases decreases; decreases decreases; increasesarrow_forward
