Haha...
I love it when my notes from class don't make any sense and the professor's slides has nothing but diagrams I can't understand without explanation. For example, straight from my outline:
G. circuitry
2. surround activation by light -> hyperpolarize surround PR ------|
|-- horizontal cell more hyperpolarize <- less glutamate release <-|
|--> less glycine is released by horizontal -> center cone is depolarize ~ dark ----|
hyperpolarization of ON bipolar/ <- more glutamate release from center PR <----|
depolarization of OFF bipolar
That might be trying to describe lateral inhibition, but I can't quite tell...
As you've noticed, I like using arrows to describe steps in a process.
WHY IS THE VISUAL SYSTEM SO LOGICALLY BACKWARD?! It releases more neurotransmitter in the absense of light than in the presence of light? Light stimuli inhibits the release of neurotransmitters?!
