CS 1501: AGI Lecture 2 | Cognitive Science of AGI

Updated: Sep 17, 2020

“Why doesn’t the brain make it self-evident that it is doing all these things? ‘Oh, by the way, it is me, Brainsy—in here in your head. I am what allows you to maintain balance and chew your food; I am the reason you fall asleep or fall in love.’ Nothing in the ancient environment of brain evolution would select for brains that could reveal themselves thus. Similarly, there is nothing in our current environment to select for kidneys or livers that announce their existence and modus operandi. They just work the way they evolved to work.” 

― Dr. Patricia S. Churchland, Touching a Nerve: The Self as Brain

Class Recap:

From last class:

  1. Neuroscience focuses on lower level features (neurons, synapses), while cognitive science focuses on the study of high-level mental processes.

  2. The brain is divided into three parts - the brainstem, the cerebellum, and the cerebrum. 

  3. The brainstem regulates life functions and the cerebellum controls movement. 

  4. The cerebrum is the newest feature and has four lobes: the frontal lobe, the parietal lobe, the temporal lobes, and the occipital lobe.

  5. Memory can be divided into (mainly) Long Term Memory (Episodic and Semantic) and Short Term Memory (working memory).

  6. The Limbic System is a crucial component of the brain that is responsible for emotions, fear, and behavioral responses.
