[HTML][HTML] 1024-channel electrophysiological recordings in macaque V1 and V4 during resting state

X Chen, A Morales-Gregorio, J Sprenger… - Scientific data, 2022 - nature.com
Co-variations in resting state activity are thought to arise from a variety of correlated inputs to
neurons, such as bottom-up activity from lower areas, feedback from higher areas, recurrent …

[PDF][PDF] Trans-thalamic pathways: strong candidates for supporting communication between functionally distinct cortical areas

B Zajzon, A Morales-Gregorio - The Journal of Neuroscience, 2019 - Soc Neuroscience
The thalamus was long considered a passive relay of sensory information with little or no
active role in higher cognitive functions. However, mounting evidence suggests that thalamic …

Bringing anatomical information into neuronal network models

SJ van Albada, A Morales-Gregorio… - … modelling of the brain …, 2021 - Springer
For constructing neuronal network models computational neuroscientists have access to
wide-ranging anatomical data that nevertheless tend to cover only a fraction of the parameters …

Neural manifolds in V1 change with top-down signals from V4 targeting the foveal region

A Morales-Gregorio, AC Kurth, J Ito, A Kleinjohann… - bioRxiv, 2023 - biorxiv.org
High-dimensional brain activity is often organised into lower-dimensional neural manifolds.
However, the neural manifolds of the visual cortex remain understudied. Here, we study large…

[PDF][PDF] Estimation of the cortical microconnectome from in vivo spiking activity in the macaque monkey

A Morales-Gregorio, P Dabrowska… - … Meeting CNS* 2020, 2020 - juser.fz-juelich.de
The primate brain is a complex system and many aspects of the relation between its cortical
structure and network activity remain to be understood. Bottom-up simulation approaches …

NEST 3.2

R de Schepper, R Deepu, A Morales-Gregorio… - 2022 - juser.fz-juelich.de
NEST is a simulator for spiking neural network models that focuses on the dynamics, size and
structure of neural systems rather than on the exact morphology of individual neurons. For …

Assessing the similarity of real matrices with arbitrary shape

…, AC Kurth, R Gutzen, A Morales-Gregorio… - arXiv preprint arXiv …, 2024 - arxiv.org
Assessing the similarity of matrices is valuable for analyzing the extent to which data sets
exhibit common features in tasks such as data clustering, dimensionality reduction, pattern …

Detection and Removal of Hyper-synchronous Artifacts in Massively Parallel Spike Recordings

J Oberste-Frielinghaus, A Morales-Gregorio, S Essink… - bioRxiv, 2024 - biorxiv.org
Current electrophysiology experiments often involve massively parallel recordings of
neuronal activity using multi-electrode arrays. While researchers have been aware of artifacts …

Ubiquitous lognormal distribution of neuron densities in mammalian cerebral cortex

A Morales-Gregorio, A van Meegen… - Cerebral …, 2023 - academic.oup.com
Numbers of neurons and their spatial variation are fundamental organizational features of
the brain. Despite the large corpus of cytoarchitectonic data available in the literature, the …

Cortical multi-area model with joint excitatory-inhibitory clusters accounts for spiking statistics, inter-area propagation, and variability dynamics

J Pronold, A Morales-Gregorio, V Rostami… - bioRxiv, 2024 - biorxiv.org
The primate brain uses billions of interacting neurons to produce macroscopic dynamics
and behavior, but current methods only allow neuroscientists to investigate a subset of the …
