Sir Isaac Netwotn’s three laws of motion. Three states of matter (solid, liquid, gas). We live on the third rock from the sun. Our metric system of measurement uses metre, litre, and gram. Morse code is a reliable system as the signal is made up of only three parts – a long ‘on’, the dash; a short ‘on’, the dot; and an ‘off’ signal. Do you know what SOS means in Morse code?

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

From Improve Your Learning and Memory.

Wednesday, April 22, 2009

  1. Exercise regularly and vigorously (assuming you don’t have heart trouble or other conditions that would prevent it)
  2. Lose weight
  3. Get out of the house and socialize

 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.

Blood Types – ABO

The Human ABO markers: The A, B, and O alleles

 *** March is American Red Cross Month ***

Human blood type is determined by co-dominant alleles. An allele is one of several different forms of genetic information that is present in our DNA at a specific location on a specific chromosome.

Blood Types

There are three different alleles for human blood type:

Blood types For simplicity,
we call these
IA A
IB B
i O
