Neuroscience describes memory formation as the long-term strengthening of synaptic connections. This is when the electrical and chemical signals between nerve cells become stronger and the synaptic connection is maintained for longer.

We don’t have mechanisms to suppress aggression, so it’s important to understand and control it rationally.   Human beings have been called the creators of the universe because of their superior intellect and reason.
