Non thinking. As complex as thinking?
In 1959, a scientist named Edward Gray showed that the miniscule gaps between neurons where chemical messages are sent, called synapses, come in two main varieties, which researchers later dubbed "excitatory" and "inhibitory." Inhibitory synapses act as the brakes in the brain, preventing it from becoming overexcited. Researchers thought they were less sophisticated than their…

New neurons. Old neurons…
Buried deep underneath the folds of the cerebral cortex, neural stem cells in the hippocampus continue to generate new neurons, inciting a struggle between new and old as the new attempts to gain a foothold in memory-forming center of the brain. [tip: we do not know where and how memory is stored but anyway] Researchers…

A mind anticipating everything… A human mind… God’s mind.
Scientists have shown how the brain anticipates all of the new situations that it may encounter in a lifetime by creating a special kind of neural network that is 'pre-adapted' to face any eventuality. A study shows that a seemingly miraculous pre-adaptation comes from connections between neurons that form recurrent loops where inputs can rebound…
