Statistical model of evolution of brain parcellation

We study the distribution of brain and cortical area sizes [parcellation units (PUs)] obtained for three species: mouse, macaque, and human. We find that the distribution of PU sizes is close to lognormal. We analyze the mathematical model of evolution of brain parcellation based on iterative fragmentation and specialization. In this model, each existing PU has a probability to be split that depends on PU size only. This model shows that the same evolutionary process may have led to brain…

A mesoscale connectome of the mouse brain
A brain-wide, cellular-level, mesoscale connectome for the mouse, using enhanced green fluorescent protein-expressing adeno-associated viral vectors to trace axonal projections from defined regions and cell types, and high-throughput serial two-photon tomography to image the EGFP-labelled axons throughout the brain.
Weight Consistency Specifies Regularities of Macaque Cortical Networks
Results indicate that connection weight heterogeneity plays an important role in determining cortical network specificity, high investment in local projections highlights the importance of local processing, and transmission of information across multiple hierarchy levels mainly involves pathways having low FLN values.
Correlated Connectivity and the Distribution of Firing Rates in the Neocortex
A simple model of cortical activity makes the experimentally testable prediction that synaptic efficacies onto a given cortical neuron are statistically correlated, i.e., it predicts that some neurons receive stronger synapses than other neurons.
Structural uniformity of neocortex, revisited
The number of neurons under a square millimeter of cortical surface has been reported to be the same across five cortical areas and five species [Rockel et al. (1980) Brain 103(2):221–244] despite

By examining many alternative arrangements of cortical areas, we have found that the arrangement actually present in the brain minimizes the volume of the axons required for interconnecting the

The cold spring harbor is one of the literary work in this world in suitable to be reading material and it will show the amazing benefits of reading a book.
The Kolmogorov-Smirnov Test for Goodness of Fit
Abstract The test is based on the maximum difference between an empirical and a hypothetical cumulative distribution. Percentage points are tabled, and a lower bound to the power function is charted.
