How would you make a complex cell that was sensitive to horizontal lines in the same region of the retina? How would it differ from the simple cell? I only need help on the second question

Ok so I have a Psychology assignmet due tomorrow and I made the horrible mistake of procrasinating. The course is mind and Brain or neuroscience. Therefore it mostly elates to vision. In my opinion, it has nothing to do ith Psychology but I am required to do so oh well.The question I am asking refers to simple and complex cells in the eye. I know that complex cells are formed by the joining of simple cells. However, I am not sure what is being asked when it says how does it differ? I know that complex cells are less location specific so I guess this means it would fire more easily. But, I am sure the question requires more detail. well I guess I am hurting a lot of peoples brains right now plus my own

Sensation & perception has quite a lot to do with psychology. If you want to better understand someone's behavior, you have to understand how they physically perceive their environment (for example does the client have autism, dyslexia, colorblindness, ghost pains, etc.)
I'll take a stab at answering; although the question is a little confusing.
Simple cortical cells have excitatory and inhibitory areas arranged side by side which means that they respond best to bars or lines of a particular orientation. So, like you said, cells will respond more quickly to a correctly oriented bar or line that is stationary.
Complex cortical cells respond best to movement of a correctly oriented bar or line. So these cells will respond more quickly to a correctly oriented bar or line that is also moving in a particular direction.
The only difference I can conclude would be rate of fire in relation to orientation and/or movement of the stimulus.
If your answer to the first question had to do with selective adaptation, prolonged exposure to a stimulus actually reduces responses & sensitivity of neurons to that stimulus.
email if you have questions - hope this helps!

The sensitivity to line direction is in the brain, not in the relatively crude instrument of the eye. The brain interprets and fills in, when needed.

I'm still trying to figure out what ur question has to do with Psychology.

Please...You are going to HAVE to expound on your question... It is too broad and not well enough defined for a helpful response.
I understand only the general idea.
What is it that you are working on?

dude what? Don't get it what does this have to do with psychology. Even though I hate it this thing is in the wrong category.
