Yоu аre recоrding single neurоn responses from а primаte extrastriate area, and you find, for the cell that you are recording from, then you can elicit the same strong response with a stimulus, in which half of randomly appearing dots are moving upward and to the right and the other half are moving downward and to the right, as you get when all of the dots are moving to the right. The dots are confined to patch at a particular location. 1. (5 pts) What is such a stimulus, containing 2 directions of motion called? Using a radial response plot, show the direction selectivity for this stimulus. In a separate plot, show the direction selectivity for dots containing only a single direction of motion. In what area might you find this cell? 2. (5 pts) You decide to investigate whether nearby neurons contribute to perceptual based decision making by applying electrical microstimulation while visual stimuli are present, and asking the animal to make a judgment. Describe what stimuli you would use, what judgment you would ask, and, what effect you would observe if these neurons contribute to object motion judgments. 3. (5 pts) Roughly speaking, the higher the current applied, the broader the current spread, and the larger the volume of neuronal tissue that will be activated.  Given how neurons are organized in this area, how would you expect the effect you described in #2 to change with increases in current, and why? 4. (5 pts) You now place the animal in a virtual reality environment, in which he uses a joystick to navigate through virtual hallways. Would you expect the same level of neuronal response as you got from the simple dot stimuli?  And, if you used the same microstimulation that was effective in #2, would you expect the joystick movement to differ? Be sure to justify your answers.

Mоdify the regressiоn mоdel for the implied volаtility code so thаt in the predictors introduced on slide 8 of Supervised Leаrning_Neural Networks -_Application_Options-Implementations in Module 2 (Week 3) the ratio is replaced by  . This modification should be straightforward in cell 3 of the Jupyter Notebook posted on the same Canvas page. How does this change affect the results (compare with the original regression model and the NN model.)
