The origin of dorsoventral polarity inDrosophila [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
InDrosophiladorsoventral (DV) polarity arises during oogenesis when the oocyte nucleus moves from a central posterior to an asymmetrical anterior position. Nuclear movement is a symmetry–breaking step and establishes orthogonality between the anteroposterior and the DV axes.

Subcortical Rotation and Specification of the Dorsoventral Axis in Newt Eggs [PDF]

open access: yesDevelopment, Growth & Differentiation, 1991
The specification of the dorsoventral axis in naturally polyspermic eggs of the Japanese newt, Cynops pyrrhogaster, was first examined by studies on the spatial relationship between the dorsal midline of the future body plan and the sperm entrance points (SEPs1).

Local and regional heterogeneity underlying hippocampal modulation of cognition and mood. [PDF]

open access: yes, 2014
While the hippocampus has been classically studied for its role in learning and memory, there is significant support for a role of the HPC in regulating emotional behavior.

Distinct Properties of Long-Term Potentiation in the Dentate Gyrus along the Dorsoventral Axis: Influence of Age and Inhibition

open access: yesScientific Reports, 2017
The hippocampus is important for spatial navigation, episodic memory and affective behaviour. Increasing evidence suggests that these multiple functions are accomplished by different segments along the dorsal-ventral (septal-temporal) axis.

Prickle1 is required for EMT and migration of zebrafish cranial neural crest [PDF]

open access: yes, 2019
The neural crest—a key innovation of the vertebrates—gives rise to diverse cell types including melanocytes, neurons and glia of the peripheral nervous system, and chondrocytes of the jaw and skull.

Synthetic epoxy-pregnan steroids: effects on anxiety behavior in rats [PDF]

open access: yes, 2016
Neurosteroids like 3α-OH-5α-pregnan-20-one (allopregnanolone) and 3α-OH-5β-pregnan-20-one (pregnanolone) modulate the γ-aminobutyric acid-A (GABAA) receptor function and produce several effects that can be considered for therapeutical pruposes like ...

Extraocular motoneuron pools develop along a dorsoventral axis in zebrafish, Danio rerio

open access: yesThe Journal of comparative neurology, 2016
Both spatial and temporal cues determine the fate of immature neurons. A major challenge at the interface of developmental and systems neuroscience is to relate this spatiotemporal trajectory of maturation to circuit‐level functional organization.

Larval trematodes infecting the South-American intertidal mud snail Heleobia australis (Rissooidea: Cochliopidae) [PDF]

open access: yes, 2014
Larval trematodes infecting the snail Heleobia australis (Cochliopidae) from the Bahía Blanca estuary, Argentina were surveyed for two years. A total of 7,504 snail specimens was dissected and the larval stages of 15 different trematodes were recovered ...

Gavity and Microtubules in Dorsoventral Polarization of The Xenopus Egg [PDF]

open access: yesDevelopment, Growth & Differentiation, 1990
In Xenopus laevis, the dorsoventral axis of the embryo is specified by a 30° relative rotation between the cortex and the cytoplasm of the fertilized egg, and a cortical array of parallel microtubules may be part of the rotation machinery (7). The parallel microtubules are aligned with the sperm entry point in most of the eggs as expected, since the ...

Requirement for Slit-1 and Robo-2 in zonal segregation of olfactory sensory neuron axons in the main olfactory bulb [PDF]

open access: yes, 2007
The formation of precise stereotypic connections in sensory systems is critical for the ability to detect and process signals from the environment. In the olfactory system, olfactory sensory neurons (OSNs) project axons to spatially defined glomeruli ...
