question related to neuron spiking

Hi,

When I read papers about neuron spiking or bursting, there are two terms 
I don't really understand:

afterhyperpolarization(AHP)
after-depolarization(ADP)

I understand Hodgkin-Huxley mechanism. And I know Potassium channel 
activation causes AHP and brings membrane potential back. But a paper 
has a description "spike trains with deep, monophasic AHPs...". Does the 
  shape of AHP tell something significant? Could you give me more info 
about this issue?

I have no idea what ADP is. Could you also help me?

Thank you very much.


Best Regards,
Xiaoshen Li
