    Study Notes

    Descartes' Dualism and Arguments Against Materialism

    • Materialism is the idea that mental life comes from physical brain.
    • Dualism, found in most religions and philosophies, is the idea that humans possess both material and spiritual parts.
    • Descartes was a proponent of dualism and argued that while animals are material, humans have a non-material nature.
    • Descartes made two arguments for non-material nature: humans can do things no machine could, and humans do not feel like bodies.
    • Descartes knew about robots in the 17th century and argued that human behavior is too complex to be explained by simple stimuli response.
    • Descartes' second argument is based on intuition and the method of doubt.
    • The method of doubt asks what can be questioned, and Descartes observed that many beliefs could be false.
    • Descartes argued that consciousness cannot be doubted, leading to his famous line "I think, therefore I am."
    • Descartes believed the soul is entirely distinct from the body and does not depend on a material thing.
    • Descartes' arguments against materialism continue to persuade many people today.
    • Descartes' ideas have been expanded upon by modern-day philosophers who argue that humans may be simulations or brains in a vat.
    • The concern about reality and existence is ancient but is best articulated in the movie The Matrix.

    The Brain: The Most Complex Machine in the Known Universe

    • The brain is the physical seed of thought and the source of our mental life and consciousness.
    • Despite its complexity and importance, the brain looks unappealing and meaty when taken out of the head.
    • Neurons are the smallest relevant parts of the brain and the focus of most research in neuroscience.
    • Neurons receive signals from other neurons through dendrites, which either excite or inhibit them.
    • The cell body sums up the pluses and minuses from dendrites, and when it reaches a threshold, neural firing occurs.
    • Neural firing takes place through the axon, which is much longer than the dendrites and is surrounded by a fatty tissue called the myelin sheath.
    • Neurons sum up and transmit information, and there are billions upon billions of neurons, each connecting to thousands of other neurons.
    • Neurons come in three flavors: sensory, motor, and interneurons.
    • Neuron firing is all or nothing, but neurons can code for intensity in different ways, such as the number of neurons that fire.
    • The brain is the most complicated machine in the universe because of its incredible internal structure and complexity, which cannot be replicated in any machine.
    • The brain consists of two halves, the left and right halves, which interact with each other.
    • The study of the biological basis of thought is called neuroscience because it all comes from the neurons.

    Neurotransmitters, Drugs, and Computational Neuroscience

    • Curare is a drug that blocks motor neurons, leading to paralysis and death in large doses.
    • Alcohol inhibits a part of the brain responsible for inhibition, making people more exuberant, but can also lead to passing out and death in large doses.
    • Amphetamines and cocaine increase the amount of norepinephrine, responsible for general arousal.
    • Prozac and L-Dopa increase the supply of dopamine or serotonin, relevant for Parkinson's and depression.
    • Drugs work by influencing neurotransmitters either by directly pumping in more or increasing the supply in different ways.
    • Neurons form clusters or networks that do interesting things like recognizing faces or walking upright.
    • Computational neuroscience aims to understand how neurons are wired up to do interesting things.
    • The brain is highly resistant to damage due to how information and capacitors are distributed across neurons.
    • The brain is wired up to work very fast despite the slowness of brain tissue and neurotransmitters.
    • Massively parallel systems and complicated neural networks are being developed to mimic the brain's wiring for more efficient computing.
    • The brain's wiring cannot be compared to a computer's due to its resilience and speed.
    • Higher-level explanations of how people learn language or recognize faces will be given instead of direct explanations in terms of neurons.
