How neural network training methods are modeled after the human brain

Much of what makes us human is the power of our brain and cognitive abilities. The human brain is a somewhat miraculous organ that gives humans the power to communicate, imagine, plan and write. However, the brain is a mystery; we don't know quite how it works. The brain has long perplexed scientists, researchers, philosophers and thinkers on the mechanisms of cognition and consciousness. When AI started to gain popularity decades ago, there was debate as to how to make a machine "learn," since developers still had little idea how humans learned.
