FGF and retinoic acid activity gradients control the timing of neural crest cell emigration in the trunk [PDF]

open access: yes, 2011
Coordination between functionally related adjacent tissues is essential during development. For example, formation of trunk neural crest cells (NCCs) is highly influenced by the adjacent mesoderm, but the molecular mechanism involved is not well ...

A Neural Pathway for Nonreinforced Preference Change [PDF]

open access: yesTrends in Cognitive Sciences, 2020
How is value processed in the brain to inform decision making? A plethora of studies describe how preferences are shaped by experience with external reinforcements. While research on this reinforced pathway is well established, far less research has explored the neural pathways promoting preference change in the absence of external reinforcements. Here,

Reviewing the mechanism of propofol addiction

open access: yesAll Life, 2023
Propofol is widely used as a short-acting intravenous anaesthetic for the induction and maintenance of anaesthetic sedation. The application of propofol is expanding due to its advantages and the increasing demand for painless diagnosis and treatment ...

Cognitive Neural Prosthetics: Brain Machine Interfaces Based in Parietal Cortex [PDF]

open access: yes, 2005
Systems neuroscience has recently emerged as an applied field in the form of neural prosthetic development. This integration of empirical systems neuroscience with engineering in order to develop functional interfaces between external devices and the ...

Molecular mechanisms separating two axonal pathways during embryonic development of the avian optic tectum [PDF]

open access: yes, 1991
During embryonic development of the avian optic tectum, retinal and tectobulbar axons form an orthogonal array of nerve processes. Growing axons of both tracts are transiently very closely apposed to each other. Despite this spatial proximity, axons from

Building and manipulating neural pathways with microfluidics [PDF]

open access: yesLab on a Chip, 2010
Communication between different brain regions, and between local circuits in the same brain region, is an important area of study for basic and translational neuroscience research. Selective and chronic manipulation of one of the components in a given neural pathway is frequently required for development and plasticity studies.

Flexible and Stable Value Coding Areas in Caudate Head and Tail Receive Anatomically Distinct Cortical and Subcortical Inputs

open access: yesFrontiers in Neuroanatomy, 2017
Anatomically distinct areas within the basal ganglia encode flexible- and stable-value memories for visual objects (Hikosaka et al., 2014), but an important question remains: do they receive inputs from the same or different brain areas or neurons?

Postnatal development of retrosplenial projections to the parahippocampal region of the rat

open access: yeseLife, 2016
The rat parahippocampal region (PHR) and retrosplenial cortex (RSC) are cortical areas important for spatial cognition. In PHR, head-direction cells are present before eye-opening, earliest detected in postnatal day (P)11 animals.

The Cross-Talks Among Bone Morphogenetic Protein (BMP) Signaling and Other Prominent Pathways Involved in Neural Differentiation

open access: yesFrontiers in Molecular Neuroscience, 2022
The bone morphogenetic proteins (BMPs) are a group of potent morphogens which are critical for the patterning, development, and function of the central nervous system.
