What are the two types of graded potentials?
What are the two types of graded potentials? Graded potentials can be of two sorts, either they are depolarizing or hyperpolarizing (Figure 1). Are EPSPs graded potentials? Graded potentials that make the membrane potential less negative or more positive, thus making the postsynaptic cell more likely to have an action potential, are called excitatory postsynaptic […]

How do we convert light into nerve impulses?
How do we convert light into nerve impulses? The light is mapped as an image along the surface of the retina by activating a series of light-sensitive cells known as rods and cones. These photoreceptor cells convert the light into electrical impulses which are transmitted to the brain via nerve fibers. How is light transmitted […]
