Computation and the single neuron
Article Abstract:
Man's perceptions, actions and memories are dictated by his brain's neurons and their networks. A study of information processing and storage, or computation and memory, at the single-cell level was undertaken. It showed that the brain, when computing, serves much like a hybrid computer. Nerve cells convert incoming digital pulses into spatially distributed variables, postsynaptic membrane potential and calcium redistribution. On the other hand, memory resides in dendrites, cell body, presynaptic terminal, in the density and exact voltage-dependency of ionic conductances and in the configuration of certain proteins in the postsynaptic terminals.

Imagery neurons in the human brain
Article Abstract:
Research is presented describing the recording of single neurons in the medial temporal lobe of the human brain while the subjects were imagining images they had previously viewed, in order to investigate the neuronal substrates of visual recall. There was a large majority of identical selectivity between the neurons that fired selectively during vision and those that fired selectively during imagery.

Quantum mechanics in the brain
Article Abstract:
The quantum mechanics in the brain is explained by Schrodinger's celebrated thought experiment where a sealed box contains the quantum superposition of both a dead and a live cat. It predicts that as soon as the photons from the quantum system encounter a classical object, such as the retina of the observer, quantum superposition is lost and the cat is either dead or alive.
