Kaas J, Stepniewska I
Curr Opin Neurobiol
. 2023 Sep;
83:102783.
PMID: 37734361
Our research focused on defining and characterizing parieto-frontal circuits for specific actions in primates. Part of the posterior parietal cortex is divided into eight or more domains where electrical stimulation...

531(17):1752-1771.
PMID: 37702312
In this study, thalamic connections of the caudal part of the posterior parietal cortex (PPCc) are described and compared to connections of the rostral part of PPC (PPCr) in strepsirrhine...

J Comp Neurol
. 2023 Apr;
531(18):1897-1908.
PMID: 37118872
This review summarizes our findings obtained from over 15 years of research on parietal-frontal networks involved in the dorsal stream of cortical processing. We have presented considerable evidence for the...

Cereb Cortex
. 2023 Feb;
33(11):7258-7275.
PMID: 36813296
The posterior parietal cortex (PPC) of squirrel monkeys contains subregions where long trains of intracortical microstimulation evoke complex, behaviorally meaningful movements. Recently, we showed that such stimulation of a part...

J Comp Neurol
. 2022 Sep;
531(1):25-47.
PMID: 36117273
In prosimian galagos, the posterior parietal cortex (PPC) is subdivided into a number of functional domains where long-train intracortical microstimulation evoked different types of complex movements. Here, we placed anatomical...

Philos Trans R Soc Lond B Biol Sci
. 2021 Dec;
377(1844):20210293.
PMID: 34957843
Early mammals were small and nocturnal. Their visual systems had regressed and they had poor vision. After the extinction of the dinosaurs 66 mya, some but not all escaped the...

Comput Diffus MRI
. 2021 Aug;
2019:193-201.
PMID: 34456460
Diffusion-weighted magnetic resonance imaging (DW-MRI) allows for non-invasive imaging of the local fiber architecture of the human brain at a millimetric scale. Multiple classical approaches have been proposed to detect...

. 2021 Jun;
11766:573-581.
PMID: 34113926
Intra-voxel models of the diffusion signal are essential for interpreting organization of the tissue environment at micrometer level with data at millimeter resolution. Recent advances in data driven methods have...

J Comp Neurol
. 2021 Feb;
529(10):2789-2812.
PMID: 33550608
Previous studies in prosimian galagos (Otolemur garnetti) have demonstrated that posterior parietal cortex (PPC) is subdivided into several functionally distinct domains, each of which mediates a specific type of complex...

PMID: 32089583
Diffusion weighted magnetic resonance imaging (DW-MRI) is interpreted as a quantitative method that is sensitive to tissue microarchitecture at a millimeter scale. However, the sensitization is dependent on acquisition sequences...
