Cognitive Neuroscience
This guide helps you get your bearings in Cognitive Neuroscience before you start exploring the interactive timeline, framework graph, and concept maps.
Before You Dive In
- Cognitive neuroscience bridges psychology and neuroscience — it asks "what brain mechanisms support cognition?", not just "what are the brain parts?".
- The field was transformed by neuroimaging (fMRI, PET) in the 1990s, but lesion studies and electrophysiology remain essential.
- Start with the localization vs. network debate — early neuroscience mapped functions to regions, modern neuroscience emphasizes distributed circuits.
- Knowing basic neuroanatomy (cortical lobes, hippocampus, prefrontal cortex) is a prerequisite for understanding everything else in the field.
Key Terms to Know
fMRIFunctional magnetic resonance imaging; measures blood flow as a proxy for neural activity.
Neural plasticityThe brain's ability to reorganize its structure and function in response to experience.
Default mode networkBrain regions active during rest and self-referential thought, not task-focused cognition.
Prefrontal cortexBrain region crucial for executive functions like planning, decision-making, and impulse control.
Double dissociationEvidence that two functions rely on different brain mechanisms (lesion in A impairs X not Y, and vice versa).
Common Confusions
"We only use 10% of our brain" — a persistent myth; all brain regions are functionally active.
Assuming fMRI images show exactly what the brain is "doing" — they show blood flow correlates, not direct neural activity.
Thinking cognitive neuroscience has "replaced" cognitive psychology — functional-level theories remain necessary even with neural data.

2011How to Use the Interactive View
1
Explore the timeline
Open the interactive view and scan the framework timeline. Which frameworks came first? Which ones overlap? Where are the big transitions?
2
Read the articles
Click into individual frameworks to read what each one claims, where it came from, and how it relates to its neighbors.
3
Check the concept map
See how the key ideas within a framework connect. This is useful for figuring out what to learn first and what depends on what.
4
Test yourself
Take the quiz for any framework you've read about. It's a quick way to find out whether you actually understood the core ideas or just skimmed them.
