	Neuropsychology is the branch of psychology that deals with how the brain and the rest of the nervous system influence a person's cognition and behaviors. Neuropsychologists often focus on how injuries or illnesses of the brain affect cognitive functions and behaviors. It is the scientific bridge between '''Neuroscience''' (the study of the hardware) and '''Psychology''' (the study of the software). By performing detailed assessments of memory, language, and executive function, neuropsychologists can pinpoint brain damage, differentiate between different types of dementia, and design rehabilitation plans to help the brain recover.

Neuropsychology is the branch of psychology that deals with how the brain and the rest of the nervous system influence a person's cognition and behaviors. Neuropsychologists often focus on how injuries or illnesses of the brain affect cognitive functions and behaviors. It is the scientific bridge between **Neuroscience** (the study of the hardware) and **Psychology** (the study of the software). By performing detailed assessments of memory, language, and executive function, neuropsychologists can pinpoint brain damage, differentiate between different types of dementia, and design rehabilitation plans to help the brain recover.

== Remembering ==
* '''Neuropsychology''' — The study of the relationship between brain function and behavior.
* '''Aphasia''' — An impairment of language, usually caused by left hemisphere damage either to Broca's area (impairing speaking) or to Wernicke's area (impairing understanding).
* '''Amnesia''' — A partial or total loss of memory.
* '''Agnosia''' — The inability to interpret sensory information even though the senses are intact (e.g., "face blindness").
* '''Apraxia''' — Difficulty with skilled movement even though the muscles are strong.
* '''Executive Function''' — High-level mental processes (planning, focus, self-control) managed by the prefrontal cortex.
* '''Plasticity''' — The brain's ability to reorganize itself by forming new neural connections.
* '''Lesion''' — Tissue destruction; can be naturally occurring (stroke) or experimental.
* '''Hemispheric Specialization''' — The idea that certain functions (like language or spatial awareness) are more dominant in one side of the brain.
* '''Phineas Gage''' — A famous case study in neuropsychology where a metal rod through the frontal lobe changed a man's personality.
* '''Dementia''' — A chronic or persistent disorder of the mental processes caused by brain disease or injury.
* '''Traumatic Brain Injury (TBI)''' — Brain dysfunction caused by an outside force, usually a violent blow to the head.
* '''fMRI (Functional Magnetic Resonance Imaging)''' — A technique for revealing blood flow and, therefore, brain activity.
* '''EEG (Electroencephalogram)''' — An amplified recording of the waves of electrical activity sweeping across the brain's surface.

Neuropsychology is about mapping "Functions" to "Structures."

**The Logic of Disconnection**: Neuropsychologists learn how the brain works by seeing what happens when it *breaks*.
* **Broca's Area (Frontal Lobe)**: Damage here leads to "Non-fluent" aphasia—the person knows what they want to say but can't produce the words.
* **Wernicke's Area (Temporal Lobe)**: Damage here leads to "Fluent" aphasia—the person speaks easily but the words make no sense ("word salad").
This proves that "speaking" and "understanding" are separate processes in the brain.

**The "Where" vs. "What" Streams**:
* **The Ventral Stream (Temporal)**: Helps us recognize *what* an object is. Damage here leads to **Visual Agnosia** (you can see the object but can't name it).
* **The Dorsal Stream (Parietal)**: Helps us know *where* an object is and how to interact with it. Damage here leads to **Optic Ataxia** (you know what it is but can't reach for it correctly).
