Cognitive Neuroscience (Ed. 5) - Chapters 1-4: Core
Concepts for Exams
Chapter 1: Introduction to Cognitive Neuroscience / Historical
Perspectives
● Core Idea: Cognitive Neuroscience is the interdisciplinary field that studies how the
brain enables mental functions (cognition). It's the meeting of psychology (mind) and
neuroscience (brain).
● Mind-Brain Problem:
○ Dualism: Mind and brain are separate entities (e.g., Descartes). Concept:
How can something non-physical interact with something physical?
○ Materialism: Mind is a product of the brain and its physical processes.
Concept: The brain is the mind, or the mind emerges from brain activity. (This
is the prevailing view in cognitive neuroscience).
● Historical Roots & Key Shifts:
○ Early Views: Ancient Egyptians (heart over brain), Greeks (brain as seat of
intellect, or not).
○ Localization vs. Holism:
■ Phrenology (Gall & Spurzheim): Early, flawed attempt at strong
localization (bumps on skull = personality traits). Concept: Idea that
, specific brain areas have specific functions, but methodologically
unsound.
■ Flourens (lesion studies): Challenged strict localization, brain acts
as a whole. Concept: Brain has equipotentiality, or distributed
functions.
■ Broca & Wernicke: Critical evidence for localization of language.
Damage to specific areas leads to specific language deficits
(aphasias). Concept: Specific cognitive functions can be linked to
specific brain regions.
○ Neuron Doctrine (Cajal): Revolutionized understanding of neural structure.
The nervous system is made of individual cells (neurons), not a continuous
net (Golgi's "nerve net theory"). Concept: Neurons are the fundamental
building blocks of the nervous system and transmit signals.
○ Cognitive Revolution (mid-20th century): Shift from pure behaviorism back
to studying internal mental processes. Influenced by computers (information
processing metaphor). Concept: The mind can be understood as processing
information, and this processing is implemented in the brain.
● Modern Cognitive Neuroscience: Uses interdisciplinary approaches (psychology,
computer science, linguistics, biology, medicine) and diverse methods.
Modularity vs. Distributed Processing:
● Localization implies modularity (specialized brain areas for specific functions).
