protocol_21
Protocol_21.m - follow up protocol 1 after protocol 19 double effector test screen. Based on protocol 19 Includes: - greyscale interval frame. - slower curtain stimuli - fast grating stimuli - slower grating stimuli. Created new: - greyscale background pattern for interval - 30 deg and 60 deg grating patterns that move by 2 pixels every frame instead of 1 in order to mimic double the speed.
Used 30 deg (16 pixels) curtains. Ended up using 32 pixel curtains in the p27 protocol to match the number of pixels of one white - black bar for the 60 deg gratings.
Results and analysis can be found in the Numbers file “2502_follow_up_protocols”.
