Assessing differential effects of single and accelerated low‐frequency rTMS to the visual cortex on GABA and glutamate concentrations

open access: yesBrain and Behavior, 2020
Background The application of repetitive transcranial magnetic stimulation (rTMS) for therapeutic use in visual‐related disorders and its underlying mechanisms in the visual cortex is under‐investigated.

Inter-areal coordination of columnar architectures during visual cortical development

open access: yes, 2008
The occurrence of a critical period of plasticity in the visual cortex has long been established, yet its function in normal development is not fully understood.

Eye position representation in human anterior parietal cortex [PDF]

open access: yes, 2008
Eye position helps locate visual targets relative to one's own body and modulates the distribution of attention in visual space. Whereas in the monkey, proprioceptive eye position signals have been recorded in the somatosensory cortex, in humans, no ...

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

Latency and Selectivity of Single Neurons Indicate Hierarchical Processing in the Human Medial Temporal Lobe [PDF]

open access: yes, 2008
Neurons in the temporal lobe of both monkeys and humans show selective responses to classes of visual stimuli and even to specific individuals. In this study, we investigate the latency and selectivity of visually responsive neurons recorded from ...

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]

open access: yes, 2001
The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

The Visual Mismatch Negativity Elicited with Visual Speech Stimuli

open access: yesFrontiers in Human Neuroscience, 2013
The visual mismatch negativity (vMMN), deriving from the brain’s response to stimulus deviance, is thought to be generated by the cortex that represents the stimulus. The vMMN response to visual speech stimuli was used in a study of the lateralization of

Generation of Direction Selectivity by Isotropic Intracortical Connections [PDF]

open access: yes, 1992
To what extent do the mechanisms generating different receptive field properties of neurons depend on each other? We investigated this question theoretically within the context of orientation and direction tuning of simple cells in the mammalian visual ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...
