Flashcards in Chapter 2: Cognitive Neuroscience Deck (28):
Different parts of the brain are responsible for different cognitive functions.
The study of the shape, size, and protrusions and dents of the cranium to understand their relationship with mental activities, abilities, and traits.
Localization of Function
The idea that there is a direct correspondence between specific cognitive function and specific parts of the brain.
Law of Mass Action
Learning and memory depend on the mass of brain tissue remaining, rather than properties of individual cells.
Law of Equipotentiality
Even though some areas of the brain may become specialized for certain tasks, any part of an area can do the job of another area (within limits).
Mind and brain are two separate entities that interact and influence one another.
"Mind" is a by-product of physical body function (including the brain) and has no role in determining behaviour.
"Mind" and brain are two aspects of the same reality (i.e. every event in the mind also has an event in the brain).
"Mind" events and neural events share the same structure; an experience and its corresponding brain process share the same pattern.
The loss of the ability to produce speech due to damage in Broca's Area.
The part of the left hemisphere that is responsible for how words are spoken .
The loss of ability to comprehend speech due to damage in Wernicke's Area.
The part of the left hemisphere that is responsible for speech comprehension.
Communication between the brain's hemispheres through the corpus callosum.
A condition created by damaging the corpus callosum.
Event-Related Potentials (ERP)
An electrical signal produced by the brain after exposure of a stimulus
Positron Emission Tomography (PET)
An imaging method where participants are injected with a radioactive substance that circulates to the brain which allows the scanner to be able to detect the flow of blood to certain areas of the brain.
Functional Magnetic Resonance Imaging (fMRI)
A non-radioactive, magnetic procedure which can detect flow of oxygenated blood to certain areas of the brain
Non-invasive neuroimaging technique that directly measures neural activity by measuring magnetic fields produced by electrical activity (mix of fMRI and ERP).
Diffusion Tensor Imaging (DTI)
An MRI-based neuroimaging technique that allows us to see the white-matter tracts in the brain.
Neurons that share the same function or are connected
"Neurons that fire together, wire together", i.e. a CONNECTION between two neurons takes place ONLY if both neurons are firing approximately at the same time.
Many neural connections may be active at the same time.
