Three major memory systems of the brain

brainThe origin of each of the major memory systems of the brain is the vast expanse of the cerebral cortex, in particular on the highest stages of the several distinct sensory and motor processing hierarchies — the cortical association areas. The cerebral cortex provides major inputs to each of three main pathways associated with distinct memory functions as shown in studies that employ double dissociation of their functions.

Three Ways to Slow Brain Aging

 Moderate physical exercise, dietary restriction, and enriched environment stimulation are all known to be good for the brain in general and memory in particular. However, few studies have directly compared these three factors all in the same study, as has been done in the lab of Alois Strasser in the University of Veterinary Medicine in Austria. Moreover, Strasser examined also a brain chemical that is likely to cause some of the brain improvement, the so-called brain-derived neurotrophic factor (BNDF), which sustains neuron life and promotes growth of neuronal processes and synapse formation.

Humans have three brains

human brainBy James Thornton

The brain is our favorite bodily organ. It is where we feel sex, love, and beauty. It is where we get guilty, depressed, and angry. It is the most complex object in the known Universe. So complex that science has only made the first tentative steps towards understanding it.

One thing is clear though: you have three brains. There are three brains nested within your skull: the lizard brain, the dog brain, and the human brain.
