%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Audrey Effenberger % MCB 105: Systems Neuroscience % DA 8: Reichardt detectors % % Very simply, we will model visual perception of motion by taking inputs % from two visual neurons. One input is forced through a delay line. Both % the output from the primary neuron and the output from the delay line % are received by the same comparator neuron. % % The comparator measures whether the primary neuron's current input is the % same as an adjacent neuron's previous input. Essentially, it allows the % circuit to detect if the object detected by the neuron corresponding to % location A is the same object that was detected by the neuron % corresponding to location B. One can imagine that the detector can be % expanded to ``remember" the states of locations even farther in the past, % but this would be pretty inefficient in terms of needing many more wires. % % Essentially, movement is defined here as detection of something in a % different location being repeated exactly in the adjacent location one % timestep later. One drawback is that because the dinosaur's limbs move in

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
