Lecture Notes - The Human Brain (Professor Nancy Camwisher)

Introduction

  • Class begins promptly at 11:05.
  • Professor Nancy Camwisher introduces herself.
  • Overview of the day's agenda:
    • Brief story (about 10 minutes).
    • Discuss the reasons for studying the human brain.
    • Cover course mechanics and grading details.

Story Time

  • Professor shares a true story related to a friend named Bob.
  • The story involves Bob experiencing a medical emergency while staying at the professor's house.
  • Themes in the story:
    • Nature of the human mind and organization of the brain.
    • Recovery after brain damage.
    • Resilience, privilege, and expertise in Cambridge society.

Incident Details

  • Bob was preparing for a conference when he collapsed.
  • EMTs found no immediate issues and suggested to go to the ER.
  • Tests at Mount Auburn Hospital did not reveal any problems initially.
  • Professor had concerns about Bob's brain due to previous signs of navigational deficits.

Realization

  • Professor recalls worrying about Bob's brain due to previous indications of navigation issues.
  • Examples of Bob’s navigational difficulties shared:
    • Directions confusion.
    • Getting lost in familiar places.
  • The episode leads to the discovery of a brain tumor (meningioma) on a scan.

Themes Derived from the Story

  1. Structure of the Brain
    • Brain has specific regions that serve different functions.
  2. Brain Damage and Recovery
    • Specific mental abilities can be lost without affecting overall IQ.
  3. Research Implications
    • Understanding brain function can lead to better scientific inquiry about the mind.
  4. Methods of Study
    • Various methodologies exist to study brain functions, from behavioral observations to imaging techniques.

Why Study the Human Brain?

  1. Self-Understanding
    • The brain is central to identity and consciousness.
  2. Limits of Knowledge
    • Understanding the mind helps in evaluating the limits of human knowledge.
  3. Advancements in AI
    • Insights from brain studies can help improve AI technologies.
  4. Intellectual Quest
    • Understanding the brain is considered a monumental intellectual challenge.

How to Study the Human Brain

  • Different levels of organization in the brain can be studied:
    • Molecules, neurons, circuits, and brain regions.
  • The course will focus on how the brain gives rise to the mind through various mental functions.

Methods of Study

  • Cognitive Science:
    • Psychophysics, neuropsychology, fMRI, EEG, and MEG.
  • The course will cover various cognitive functions, including perception, language, navigation, and more.

Course Structure

  • The course will begin with basic neuroanatomy and then delve into various cognitive functions, their brain bases, and methodologies.
  • Focus will also be on understanding current research papers in the field.

Grading and Assignments

  • Midterm: 25%
  • Final: 25%
  • Weekly reading assignments and papers.
  • Quizzes to ensure comprehension of material.
  • Designing an experiment assignment towards the end of the course.

Conclusion

  • Encouragement to engage with the material and understand the complexities of studying the human brain.
  • Reminder to communicate any concerns or questions regarding the course.
