Response Variance in Functional Maps: Neural Darwinism Revisited

Response Variance in Functional Maps: Neural Darwinism Revisited

The mechanisms by which functional maps and map plasticity contribute to cortical computation remain controversial. Recent studies have revisited the theory of neural Darwinism to interpret the learning-induced map plasticity and neuronal heterogeneity observed in the cortex. Here, we hypothesize that the Darwinian principle provides a substrate to explain the relationship between neuron hetero...

Neural Darwinism and Consciousness 1 RUNNING HEAD: Neural Darwinism and Consciousness Neural Darwinism and Consciousness

Neural Darwinism (ND), also called the Theory of Neuronal Group Selection (TNGS) is a biological theory of brain development and function which is based on evolutionary and developmental principles. ND highlights the importance of selectionist processes underlying these principles. The aim of this literature review is to capture and summarize the essentials of both ND and its theoretical extens...

Neural Darwinism and consciousness.

Neural Darwinism (ND) is a large scale selectionist theory of brain development and function that has been hypothesized to relate to consciousness. According to ND, consciousness is entailed by reentrant interactions among neuronal populations in the thalamocortical system (the 'dynamic core'). These interactions, which permit high-order discriminations among possible core states, confer select...

Variability of Neuronal Responses: Types and Functional Significance in Neuroplasticity and Neural Darwinism

HIGHLIGHTS We suggest classifying variability of neuronal responses as follows: false (associated with a lack of knowledge about the influential factors), "genuine harmful" (noise), "genuine neutral" (synonyms, repeats), and "genuine useful" (the basis of neuroplasticity and learning).The genuine neutral variability is considered in terms of the phenomenon of degeneracy.Of particular importance...
