SEMANTICS BEHIND THE MIND. “The mind understands by exploiting semantics, or meaning, for the purposes of computation; constraints are built in so that although there are myriad possibilities, only a few make sense. Evolution discovered corresponding subroutines or shortcuts to speed up its processes and to construct creatures whose survival depends on making the right choice quickly.” https://lnkd.in/dBwDZAr View in LinkedIn

BAUM BACKGROUND. “Eric B. Baum has held positions at the University of California at Berkeley, Caltech, MIT, Princeton, and the NEC Research Institute. He is currently developing algorithms based on Machine Learning and Bayesian Reasoning to found a hedge fund.” https://lnkd.in/dBwDZAr View in LinkedIn

NATURE OF MIND. “Baum argues that the structure and nature of thought, meaning, sensation, and consciousness therefore arise naturally from the evolution of programs that exploit the compact structure of the world.” https://lnkd.in/dBwDZAr View in LinkedIn

NATURE OF THOUGHT. “The human brain is composed of about 100 billion nerve cells (neurons) interconnected by trillions of connections, called synapses. On average, each connection transmits about one signal per second. Some specialized connections send up to 1,000 signals per second. “Somehow… that’s producing thought." https://lnkd.in/dufBtMc View in LinkedIn

THE HUNGRY BRAIN. “In the average adult human, the brain represents about 2% of the total body weight yet it accounts for 20% of all the energy consumed, 10 times that predicted by its weight alone.” https://lnkd.in/dfdbGFX View in LinkedIn

CHEMICAL MEMORIES. “Memories are made by messenger RNA (mRNA) that encode β-actin protein. These proteins are responsible for shaping and structuring cells in the neurons. As events unfold, β-actin protein is responsible for reshaping the neurons and creating a path, retracing the synaptic steps.” https://lnkd.in/dsNd_xr View in LinkedIn

CHEMICAL MEMORIES. “The chemicals used by neurons to store memories are protein molecules. The most common are the "GluR" proteins which combine to form "AMPA" neuroreceptors. These are activated by the neurotransmitter glutamate.” https://lnkd.in/d2BtBzU View in LinkedIn
