    Study Notes

    Course Information

    • Course Title: PSYCH 3513 Introduction to Cognitive Neuroscience
    • Instructor: Dr. Brian M. Siefke, Ph.D.

    About the Instructor

    • Earned a Ph.D. in Cognitive Psychology from Ohio State University (OSU) in August 2017
    • Dissertation focused on episodic memory formation and how context changes distinctiveness
    • Earned an M.A. in Cognitive Psychology from OSU in 2013
    • Earned a B.S. in Psychology and General Science from Bowling Green State University in 2010
    • Received honors (cum laude)

    Cognitive Neuroscience

    • Defined as the intersection of cognition (awareness, perception, reasoning) and neuroscience (the study of the nervous system), creating a comprehensive understanding of the brain.
    • Explores how the brain enables mental processes (e.g., perception, thought, and consciousness).
    • Examines the organization and interactions of different brain regions.

    Effects of Multitasking and Peer Distraction

    • Research suggests that multitasking negatively impacts comprehension of lecture content.
    • Students who multitask while exposed to lecture material perform significantly worse on comprehension tests than students who do not multitask.
    • Similar results have been observed regarding peer distractions of multitasking
    • Peer distraction/multitasking negatively impacted comprehension of lectures.

    Marr's Levels of Analysis

    • A framework for analyzing complex systems, particularly the brain and computer programs.
    • Computational Level: focuses on the overall goals and purpose of a behavior or process.
    • Algorithmic Level: describes the steps, or the recipe. in algorithms for a process, providing details and mechanisms.
    • Implementation Level: concerns the physical components, substrate or underlying structure that makes it work.

    Evolutionary Perspective

    • Discusses the evolutionary origins and advantages of behaviors
    • Investigates aspects of behavior that might enhance survival or reproduction

    Timeline of the Brain Development

    • Earth formed 4.5 billion years ago
    • Biological life appeared 3.8 billion years ago
    • Primate brains emerged 34-23 million years ago (Ogliocene Epoch)
    • Larger brains evolved in great apes 23-7 million years ago
    • Human lineage diverged from primate ancestors 5-7 million years ago
    • Human brains developed 100,000 years ago
    • Theories of causation and human motivation developed
    • Modern scientific methods for brain study became prevalent in the 19th century

    Historical Perspectives

    • Ancient thinkers such as Aristotle (heart as the seat of the mind), Descartes proposing mind-body dualism.
    • Spinoza's dual aspect theory that mind and body are related through aspects
    • The influence of phrenology, with its focus on skull bumps as indicators of personality traits.
    • Localization of function, including the work of Broca and Wernicke.
    • Anti-Localizationism, like that of Pierre Flourens, and how it counteracted localizationist views
    • Clinical observations on brain lesions revealing selective impairments (e.g., Phineas Gage, HM)

    Modern Neuropsychology

    • Experiments, observations, and research by prominent thinkers (Hughlings Jackson, Claude Bernard) explored the interconnectedness of brain regions.
    • Led to a less extreme approach about localization, concentrating more on interconnectedness and interactions among brain regions.

    Neuron Doctrine and Cytoarchitectonics

    • Early 20th-century neuroanatomists (e.g., Golgi, Cajal) played crucial roles.
    • The concept of neuronal doctrine gained traction, highlighting the independent and distinct nature of nerve cells.
    • Cytoarchitectonics, focusing on neural cell-based morphology, also played a pivotal role.
    • Subsequent work helped clarify cell assemblies and learning rules (Hebbian learning) in neural networks

    Cognitive Revolution

    • The rise of computer science and artificial intelligence inspired new perspectives.
    • The idea of the brain functioning akin to a complex computer system emerged.
    • Noam Chomsky's work on language challenged behaviorist assumptions.
    • George Miller's insights on information processing capacity.

    Blood Flow in the Brain

    • Early observations (Angelo Mosso) linked brain function with pulsations or blood flow.
    • Later, advancements in radiology, allowing researchers to visualize the brain's activity, improved our understanding of blood flow in the brain
    • Development of CT, PET, and fMRI as techniques that could measure blood flow.
    • fMRI's significance was dependent on the coupling of neuronal activation with cerebral blood flow increase.

    Neuroimaging and Neurophrenology

    • Neuroimaging's role in modern-day studies of brain function.
    • Functional data is obtained from structural or topographical brain maps.

    The Enterprise of Cognitive Neuroscience

    • Focuses on how learning about the brain elucidates the mind's function, behavior, and potential to predict behavior.
    • Broader than localizing brain functions but encompasses other important aspects of the brain-mind relationship
    • Beyond "localization," other important aspects including cognitive mechanisms and how they operate within the brain

    Summary

    • Cognitive neuroscientists confront a complex brain system with numerous neurons and connections.
    • Emphasizes understanding neural mechanisms, not just their location
    • Both local and distributed roles that the brain plays in functions are considered relevant
