Layer-specific valence effect in V1 To determine the anatomic source of valence information in V1 (Fig.3a), we used high field strength fMRI at 7T combined with VASO23,24scanning. By measuring CBV responses across cortical layers (Fig.3c–e), our approach enabled layer-specific measurements ...
Neurosciences Layer-specific local and callosal projections in rat neocortex UNIVERSITY OF CONNECTICUT RamosRaddy LNeuronal lamination is a characteristic cytoarchitectonic feature of the neocortex and there exists a complex circuitry of connections among neurons found within and between cortical lamina. ...
We show that sensory processing in mouse primary somatosensory cortex (S1) was impaired in the acute phase of M1 infarctions and recovered in a layer-specific manner in the subacute phase. This layer-dependent recovery process and the anatomical connection pattern from M1 to S1 suggested that ...
The extent of ensheathment of synaptic clefts by astrocytes in layer II/III was greater than that by those in layer VI. Moreover, differences in gene expression were observed between upper-layer and deep-layer astrocytes. Importantly, layer-specific differences in astrocyte properties were ...
Cortical layer-specific differences in stimulus selectivity revealed with high-field fMRI and single-vessel resolution optical imaging of the primary visua... The mammalian neocortex exhibits a stereotypical laminar organization, with feedforward inputs arriving primarily into layer 4, local computations sh...
The retina consists of multiple cellular and synaptic layers and is nourished by two distinct (retinal and choroidal) circulations bounding the retina, separated by an avascular layer. High spatiotemporal resolution, layer-specific MRI of the retina remains challenging due to magnetic inhomogeneity-...
We also show layer-specific differences between cortical fields, for example, the F area shows low myelin in L6. In line with our hypothesis (1), our results indicate systematic differences in the microstructural profiles of the cortical fields of M1 in younger adults; we therefore refer to ...
This study sought to examine layer-specific longitudinal and circumferential systolic and diastolic strain, strain rate (SR) and diastolic time intervals in hypertensive patients with and without diastolic dysfunction. Fifty-eight treated hypertensive patients were assigned to normal diastolic function (NDF...
Nicotinic AChRs are expressed on glutamatergic inputs to layer V (LV) cells and on LV interneurons and LVI pyramidal neurons. Whether PFC layers are activated by nAChRs to a similar extent or whether there is layer-specific activation is not known. Here, we investigate nAChR modulation of all...
Our results indicate that activation of the NBM dilates cortical penetrating arteries in a layer-specific manner in magnitude and latency, presumably related to the density of cholinergic nerve terminals from the NBM. 展开 关键词: cerebral cortex diameter nucleus basalis of Meynert penetrating artery ...
