Trends in Cognitive Sciences, 2018
Neural circuits have evolved to accommodate similar information processing challenges as those faced by engineered systems. Here, we compare neural versus engineering strategies for constructing networks. During circuit development, synapses are overproduced and then pruned back over time, whereas in engineered networks, connections are initially ...

From gene networks to brain networks
Nature Neuroscience, 2003The brain's structural organization is so complex that 2,500 years of analysis leaves pervasive uncertainty about (i) the identity of its basic parts (regions with their neuronal cell types and pathways interconnecting them), (ii) nomenclature, (iii) systematic classification of the parts with respect to topographic relationships and functional systems

Metabolic Network of Nucleosides in the Brain
Current Topics in Medicinal Chemistry, 2011Brain relies on circulating nucleosides, mainly synthesised de novo in the liver, for the synthesis of nucleotides, RNA, nuclear and mitochondrial DNA, coenzymes, and pyrimidine sugar- and lipid-conjugates. Essentially, the paths of nucleoside salvage in the brain include a two step conversion of inosine and guanosine to IMP and GMP, respectively, and ...

The Brain is a Social Network. [PDF]
, 2017 Social Network Analysis is employed widely as a means to compute the probability that a given message flows through a social net- work. This approach is mainly grounded upon the correct usage of three basic graph-theoretic measures: degree centrality, closeness centrality and betweeness centrality.

Brain Imaging, Cognitive Processes, and Brain Networks
Perspectives on Psychological Science, 2010The recent, rapid expansion of the application of neuroimaging techniques to a broad variety of questions about the structure and function of mind and brain has led to much necessary and often critical introspection about what these techniques can actually tell us about cognitive processes.

Molecular networks of brain and immunity
Brain Research Reviews, 2007Exciting complexity of natural phenomena can be based on rather simple biophysical principles. For example, the genetic code is based on a double-helix of DNA formed by planar geometry of weak hydrogen bounds. On the examples of cytokine networks, immune synapse, psychoneuroimmunology and systems biology, this review paper attempts to show how ...

Training brain networks and states
Trends in Cognitive Sciences, 2014Brain training refers to practices that alter the brain in a way that improves cognition, and performance in domains beyond those involved in the training. We argue that brain training includes network training through repetitive practice that exercises specific brain networks and state training, which changes the brain state in a way that influences ...
