Document Summary
Perception: the process by which we recognize what is presented by the information provided by our senses. We don"t feel the process of perception. We are just presented with the final product. Problem solving: when we see something we don"t know and we gather evidence to decide what it is. Circuits of neurons analyze particular aspects of visual information. Knowledge in earliest stages of visual analysis has come from: Investigations of the activity of individual neurons in the thalamus and the primary visual cortex. Inserting small electrodes into various regions of visual systems of cats and monkeys. ^ action potentials created by individual neurons were studied. Animal placed in front of a screen. Position of stimulus moved around to detect the location that created the largest effect on the electrical activity of the neuron. Stimuli of various shapes was presented to detect which one created the greatest neuron response. Geography of the visual field is retained in: primary visual cortex.
