Peter Zorkoczy with a 3D model of the surface of a retinal receptor cell. He describes the characteristics of this type of model. Shot of a graphical model which represents the essentials of the n...erve networks of the cerebellum. Zorkoczy asks viewers to look for a number of basic points as these models of the biological system are examined. Zorkoczy introduces Kit Pedler. Kit Pedler with an electron micrograph of part of the retina. He describes the steps he took to build a physical model of a retinal receptor cell from a series of micrographs. Shot of his first, idealised model. Pedler points out the component parts of this receptor cell model. Pedler next explains how his more detailed and sophisticated model was arrived at. Shots of this model of the retinal receptor cell. Pedler with a physical model of several receptor cells, showing their connections with other cells and among themselves. Pedler explains how his model was arrived at. He shows and describes the apparatus which was used to build the model. Zorkoczy describes the role of the cerebellum as an introduction to the examination of a graphical model of it. Shot of transverse section of the human brain. The section of the cerebellum which is modelled is shown. The neural network seen there is simplified into a graphical model. Shot of the graphical model of a part of the cerebellar neural network. Zorkoczy points out the model's components and explains how it works. Film shots of the model in action. Film pictures of a little girl learning to drink from a cup are shown with the model. The model illustrates the learning process. Zorkoczy introduces the sequence on simulating intelligence in a digital computer. Film shots of children playing with blocks of different sizes, shapes and colours. Shots of an early attempt at artificial intelligence. A computer picks out simple objects which it scans with a T.V. camera. Harry Barrow explains how this is done, the computer prin out to aid. Film shots of the M.I.T. hand/eye model, a more sophisticated form of artificial intelligence. In this case the computer can recognize and manipulate cubes of different sizes. Commentary by Zorkoczy. Zorkoczy introduces the Winograd man/computer dialogue model. In this simulation of intelligence the computer responds to natural language and performs tasks of manipulating cubes and pyramids of different sizes and colours. Zorkoczy uses a diagram to explain what the computer will do. The diagram shows a number of cubes and pyramids which the computer will manipulate. Film sequence shows a demonstration of the Winograd computer model. A dialogue is carried on between the computer and the operator and the computer manipulates the objects above as instructed by the operator in natural language.
