Whole-brain estimates of directed connectivity for human connectomics
Connectomics is essential for understanding large-scale brain networks but requires that individual connection estimates are neurobiologically interpr…
One in five Australian scientists planning to leave the profession, survey shows
Survey reveals 17% gender pay gap and strain on industry at a time when it has been at the forefront of responding to coronavirus

Biden promises increased scientific investment if elected in 'most in-depth statement of priorities'
In the latest episode of Pod Save America — a podcast hosted by several former Obama administration staffers — the Democratic presidential nominee, former Vice President Joe Biden, laid out what Politico described as 'the most in-depth statement of...
Postsynaptic activity of inhibitory neurons evokes hemodynamic fMRI responses
Functional MRI responses are localized to the synaptic sites of evoked inhibitory neurons, but it is unknown whether, or by what mechanisms, these neu…
Influence of sample size and analytic approach on stability and interpretation of brain‐behavior correlations in task‐related fMRI data
Limited statistical power due to small sample sizes is a problem in fMRI research. Most of the work to date has examined the impact of sample size on task‐related activation, with less attention paid...
Connectomes: Mapping the mind of a fly
Scientists have created the most detailed map of the fruit fly brain to date, identifying over 25,000 neurons and 20 million synapses.
Detecting brain network communities: Considering the role of information flow and its different temporal scales
The identification of community structure in graphs continues to attract great interest in several fields. Network neuroscience is particularly concer…
Structural determinants of dynamic fluctuations between segregation and integration on the human connectome
Makoto Fukushima and Olaf Sporns report that significant contributions from global geometry and topology of the connectome, as well as from localized structural connections involving visual areas drive temporal changes in segregation and integration...
Neuroprotective Effects of Motherhood on Brain Function in Late Life: A Resting-State fMRI Study
Abstract. The maternal brain undergoes structural and functional plasticity during pregnancy and the postpartum period. Little is known about functional plasti
Developmental profile of psychiatric risk associated with voltage-gated cation channel activity
Recent breakthroughs in psychiatric genetics have implicated biological pathways onto which genetic risk for psychiatric disorders converges. However, these studies do not reveal the developmental time point(s) at which these pathways are relevant....
Information Confusion Reveals an Innate Limit of the Information Processing by Neurons
Information experiences complex transformation processes in the brain, involving various errors. A daunting and critical challenge in neuroscience is to understand the origin of these errors and their effects on neural information processing. While...
Multiscale and multimodal reconstruction of cortical structure and function
We present a semi-automated reconstruction of L2/3 mouse primary visual cortex from 3 million cubic microns of electron microscopic images, including pyramidal and inhibitory neurons, astrocytes, microglia, oligodendrocytes and precursors,...

Topological versus spectral properties of random geometric graphs
In this work we perform a detailed statistical analysis of topological and spectral properties of random geometric graphs (RGGs), a graph model used to study the structure and dynamics of complex systems embedded in a two-dimensional space. RGGs,...
Scattered slice SHARD reconstruction for motion correction in multi-shell diffusion MRI
Diffusion MRI offers a unique probe into neural microstructure and connectivity in the developing brain. However, analysis of neonatal brain imaging d…
