In this course

Hebb is foundational to computational neuroscience and theories of learning through his proposal that synaptic strength changes encode memory—the idea that repeated activation of neurons strengthens their connections. His work is invoked here to ground the cortical assembly theory being discussed, where semipermanent memory structures arise from varying synaptic weights rather than from any single dominant neural pathway. This makes Hebb essential for understanding how artificial neural networks later borrowed biological learning principles to formalize machine learning itself.

Speculations Concerning the First Ultraintelligent Machine

If we abandon interpretations of meaning in terms of linguistic transformations, such as dictionary definitions, or, in the case of statements, the two interpretations mentioned before; and if also we do not regard the behavioral interpreta…form of this theory will be adopted here. The meaning and point of the theory can be explained in terms of its applications to the linguistic activities of the brain, although the theory is usually discussed in a more general context. There…It will be assumed in this paper that there are also subassemblies that can be active without dominating the whole cortex, and also that when an assembly becomes fatigued and breaks up it leaves several of its own subassemblies active for v…

From such ideas emerged the intellectual movement called cybernetics, which attempted to combine many concepts from biology, psychology, engineering, and mathematics. The cybernetics era produced a flood of architectural schemes for making …The mystique surrounding such machines is based in part on the idea that when such a machine learns the information stored is not localized in any particular spot but is, instead, “distributed throughout” the structure of the machine’s netw…
