Definition. Evidence of brain modularity is the empirical body of findings that demonstrates that the brain is organized into semiautonomous groups of neurons and brain regions that interact with one another through relatively sparse and long-distance pathways in the brain.
What modularity means?
Broadly speaking, modularity is the degree to which a system’s components may be separated and recombined , often with the benefit of flexibility and variety in use. ... Despite these nuances, consistent themes concerning modular systems can be identified.
What is the function of modular in brain?
Modular models of the brain aid the understanding of a complex system by decomposing it into structural modules (e.g., brain regions, layers, columns) or functional modules (schemas) and exploring the patterns of competition and cooperation that yield the overall function .
What are the advantages of modularity in the brain?
Human studies have shown that modular brain networks are beneficial for cognitive performance . First, higher network modularity quantified from task-free ‘resting’ functional connectivity data is related to better working memory capacity [48] and episodic memory [33] across individuals.
Is human brain modular?
For example, gene expression in the brain is modular ; the transcriptomes of human brain regions are robustly organized into modules of coexpressed genes that reflect the underlying cellular composition of brain tissue (8), and the spatial topography of cortex is also strongly reflected in its genetic topography—the ...
Is the brain discrete?
Our work concludes that information cannot be communicated and represented reliably in the brain using a continuous representation – it has to be in a discrete form . This is a major demarcation from conventional and current wisdom.
Is the brain causal?
Yet causality may not itself be a feature of the world as much as it is a result of the way the human brain encodes and structures experience . ...
What is modularity example?
Modularity is a property that describes how replaceable the components or modules of a system are . ... Modules can be removed, replaced, or upgraded without affecting other components. For example, most desktop computers are modular because they have easily removable and upgradeable parts.
Why do we need modularity?
The Advantages of Modularization in Programming
To avoid similar poor-planning scenarios, modularization comes to help in programming. This intends to breaking up and organizing code taking into consideration the task it executes . In such a way, the code becomes reusable, easier to debug and manage.
How is modularity achieved?
Modularity is a fundamental principle of programming. It is intended to control the complexity of a software system through the use of the divide and conquer approach . A complex system can be decomposed into a set of loosely coupled, but cohesive modules.
What is Subtractivity in psychology?
So cognitive neuropsychology is a subfield of cognitive psychology, distinguished by the feature that it studies people with disorders of perception, attention, learning, memory, processing of spoken and written language, thinking, reasoning or belief formation, with the aim of learning more about the normal functional ...
What is anatomical modularity?
The second assumption, the anatomical modularity assumption, is the idea that the cognitive modules which compose cognition (or at least most of them) each reside in some specific and relatively small portion of the brain (Coltheart, 2001. ... “Assumptions and methods in cognitive neuropsychology”.
What is localization of function in psychology?
the concept that specific parts of the cerebral cortex are relatively specialized for particular types of cognitive and behavioral processes . Also called cortical localization.
What is modularity in psychology?
n. a theory of the human mind in which the various components of cognition are characterized as independent modules , each with its own specific domain and particular properties.
What is a modular organizational structure?
Modular organizations: A modular organization involves several largely independent bodies that can rearrange and work with different other departments as needed .
What does modular mean in biology?
Introduction. Modularity has become a central concept in evolutionary biology (Wagner et al. 2007). A system is modular if it can be divided into multiple sets of strongly interacting parts that are relatively autonomous with respect to each other .
