 A Single Neuron Can Recognize Patterns

Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables. It has been previously proposed that non-linear properties of dendrites enable neurons to recognize multiple patterns. In this paper we extend this idea by showing that a neuron with several thousand synapses arranged along active dendrites can learn to accurately and robustly recognize hundreds of unique p...

 Juxtaposition is the Spice of Life

Let me suggest a new axiom: juxtaposition is the spice of life. Humanity’s biggest talent, unique to us, is juxtaposing, finding and operating novel relationships between things or ideas... Recent ideas on neural activity suggest that the brain operates in a very associative way, with small neuron clusters containing core concepts, rather in the way a battery holds a trickle charge. These core concepts would be irreducibly small fragments of sounds or sights, or any phenomena that you exper...

The brain can be wired more ways then there are atoms in the Universe, and new combinations create new ideas and innovations.
