From Turing's Machine to Neuromorphic Processors

The Von Neumann architecture, which has dominated computing for eight decades, is today reaching its physical limits when faced with the energy and cognitive efficiency of the human brain. While classical processors strictly separate the processing unit from memory — creating the well-known "Von Neumann bottleneck" — neuromorphic architectures merge these two entities. Historically, we have moved from the first software perceptrons running on massive CPUs to chips such as Intel's Loihi 3 or BrainChip's Akida, which physically replicate synaptic structure.

Santiago Ramón y Cajal, bent over his microscope at the end of the 19th century, described neurons as the "mysterious butterflies of the soul," unaware that a century and a half later we would attempt to map every beat of their wings in bits. What began as a purely anatomical quest to understand the secrets of consciousness has today transformed into a frontier discipline where the prefix "Neuro-" no longer refers solely to a medical field, but to the pillar of a new computational and communicative revolution.
