Interactions all the way down a Friedrich & Assadollahi
Problem of Information Calow, 1976: • The human body contains about 5x1028 bits of information in its molecular arrangement, but the human genome only contains about 105 bits of information. => Where does the information come from?
Problem of Information • How domain- and representation-specific is innate knowledge? • How direct is the link between gene and behaviour?
Interactions • Molecular and and cellular interactions at the lowest level • Brain systems on the intermediate level • The whole individual and the environment on the highest level
Brain systems interaction Chick imprinting: Imprinting is the process by which newly hatched birds become attached to the first conspicious object they see. • Predisposition to attend toward head and neck region of objects that possess configurations of features found in hens. • Learning system in the forehead (Intermediate and Medial Hyperstriatum Ventrale, IMHV) for imprinting.
Brain systems interaction Three possible forms of interation: • None • Attention system activates learning • Attention system acts as a filter
Connectionist Model o inhibition, > excitiation => hysteresis.
Connectionist Model Uses hysteresis for movement independent representation5
