TLDR
The human brain is a formidably complex network, the seat of cognition and consciousness and many other remarkable features, including the capacities of growth, self-organisation, reorganisation and the ability to recover from significant damage.Abstract:
The human brain is a formidably complex network, the seat of cognition and consciousness and many other remarkable features, including the capacities of growth, self-organisation, reorganisation and the ability to recover from significant damage. This combined dynamic capability is known as plasticity. Considerable neuro-reorganisation is a feature of the brain commonly thought to be restricted to childhood (the Kennard Principle); however, it is known to be a feature of adult brains as well. This paper provides a brief history of early theory and research, still valid today, on brain or neuroplasticity before discussing how current network theory and new brain mapping research on modularity can be synthesised to provide insight into this adaptive function from structure.read more

Dynamical consequences of lesions in cortical networks.

TL;DR: It is concluded that lesions of parietal regions and frontal regions have the greatest potential to disrupt the integrative aspects of neocortical function.

TL;DR: It is suggested that one way forward for analysis of brain networks will be to quantify aspects of their organization which are likely to be generic properties of a broader class of biological systems.

Speaking without Broca's area after tumor resection
TL;DR: A case study of a patient speaking without Broca's area illustrates the efficiency of brain plasticity, and shows the necessity to broaden pre-, peri- and post-surgery language and cognitive assessments.

TL;DR: Numerical simulations with connected Hindmarsh–Rose neurons are presented in which, starting from random connection distributions, small-world networks evolve as a result of applying an adaptive rewiring rule.

A Tale of Two Cases: Lessons for Education From the Study of Two Boys Living With Half Their Brains
TL;DR: In this paper, the complementary cases of Nico and Brooke, two high-functioning adolescents, who have suffered the removal of an entire brain hemisphere (Nico his right and Brooke his left) to control severe epilepsy are presented.
