Plot receptive fields of simulated retinal and cortical cells. Physiologists Friend is intended for classroom demonstration of cell response properties. You can hear the cell responses as though you were doing a recording from a live animal. You can choose between photoreceptor, horizontal cell, on and off bipolar cells, on and off ganglion cells, and several types of cortical cells.
You can use bar, edge, or grating stimuli. You will hear how the cell responds as you use your mouse to move the stimulus. The stimulus orientation, contrast, size, spatial frequency can be easily manipulated through the keyboard.
