1 2 3 4 What happens at each stage on this graph?

Which graph is Depolarization? Which one is Hyperpolarization? ? ?

Which highlighted area is Absolute refractory period? What is the other period called?

What is happening at each step? Step 1 What kind of channels are these? Step 2 What is this area called? Voltage gated channels What about these? Step 3 Step 4 Chemically gated channels Step 5 Step 6

1. Which graph represents Excitatory postsynaptic What is EPSP? potential(EPSP)? 2. Which one is inhibitory postsynaptic potential(IPSP)? ? What is IPSP? ?

Which picture is represented by each? What is the difference between Chemical gated ion channels Answer And voltage-gated ion channels? Chemical gated ion channels: Voltage-gated ion channels Open when the appropriate neurotransmitter binds to the receptor Open and close in response to changes in membrane voltage
