Holding information in mind may mean storing it among synapses
Comparing models of working memory with real-world data, MIT researchers found that information resides not in persistent neural activity, but in the pattern of their connections

New version of Arbor neural network simulation library released
Arbor is a multi-compartment neural network simulation library designed to be portable across contemporary high-performance computing architectures. The most recent version is now available on EBRAINS

Coordinated multiplexing of information about separate objects in visual cortex
Sensory receptive fields are large enough that they can contain more than one perceptible stimulus

HBP researchers map the 'synaptic landscape' of a cognitive nucleus of the thalamus
Researchers from the Autonomous University of Madrid (UAM) supported by the Human Brain Project (HBP) were able for the first time to identify the origin, intranuclear distribution and size of all types of axon terminals present in a cognitive nucleus of the thalamus

A ubiquitous spectrolaminar motif of local field potential power across the primate cortex
The spectrolaminar pattern characterized by an increasing deep-to-superficial layer gradient of gamma frequency LFP power peaking in layers 2/3, and an increasing superficial-to-deep gradient of alpha-beta power peaking in layers 5/6

Illuminating a mysterious brain structure
Neuroscientists are shedding literal light on the mouse claustrum, a tiny part of the brain with an outsized number of connections

STEPS 4.0 towards large-scale biologically-relevant simulations
Simulating neurons down to the level of their biochemistry in order to understand their behavior and properties is a complex computational challenge

A mind-body interface alternates with effector-specific regions in motor cortex
Researchers have identified the Mind-Body Interface, a novel distributed network within human primary motor cortex that disrupts the famous but incorrect motor homunculus, and that exhibits strong connections to high-level control networks

Mapping neurotransmitter systems to the structural and functional organization of the human neocortex
There are collate positron emission tomography data from more than 1,200 healthy individuals to construct a whole-brain three-dimensional normative atlas of 19 receptors and transporters across nine different neurotransmitter systems.

A new way to merge electro/magnetoencephalography and tractography to measure conduction delays in multiple sclerosis
Researchers of the Human Brain Project have developed a new methodology to calculate the delay of signal propagations in brains of patients

25.10.2022
Large-scale waves of activity in the neonatal mouse brain in vivo occur almost exclusively during sleep cycles
Spontaneous electrical activity plays major roles in the development of cortical circuitry. This activity can occur highly localized regions or can propagate over the entire cortex. Both types of activity coexist during early development

NSG Virtual workshop
The Neuroscience Gateway (NSG) will host a Virtual workshop as a part of the Society for Neuroscience Annual Meeting in San Diego, November 2022

eLife’s New Model: Changing the way you share your research
From next year, eLife is eliminating accept/reject decisions after peer review, instead focusing on public reviews and assessments of preprints

Meta-connectomic analysis maps consistent, reproducible, and transcriptionally relevant functional connectome hubs in the human brain
Here, we conduct a worldwide harmonized meta-connectomic analysis by pooling resting-state functional MRI data of 5212 healthy young adults across 61 independent cohorts

How the brain focuses on what’s in mind
When holding information in mind, neural activity is more focused when and where there are bursts of gamma frequency rhythms

31.08.2022
How the brain generates rhythmic behavior
MIT neuroscientists have identified an oscillatory circuit that controls the rhythmic movement of mouse whiskers

28.08.2022
Constructive connectomics: How neuronal axons get from here to there using gene-expression maps derived from their family trees
During brain development, billions of axons must navigate over multiple spatial scales to reach specific neuronal targets, and so build the processing circuits that generate the intelligent behavior of animals

When Alzheimer’s degrades cells that cross hemispheres, visual memory suffers
Cross-hemisphere interactions are suddenly getting interesting after decades of neglect
