Here is a tangible example of the brain as a sort of sensory computer geared for survival.
10:07 - 10:17
Other segments of this course show experiments involving a dot of light strafing across a visual field, and the pertinent neurons firing (that rapid clicky noise). Some fire when the dot/stimulus moves horizontally, some fire when it moves vertically, some fire when the previous two fire simultaneously, some fire when a line of light moves in certain directions but don't fire when dots do, etc.
And you can see how complex visual computations can be made in combination of these baser computations. In the case of the grasshopper, this particular visual stimulation is somehow linked to the motor function of hopping away, seeing as this visual stimulation approximates a nearing object.
