β-adrenergic receptor-induced E-S potentiation in the dorsal and ventral hippocampus

Frontiers in Synaptic Neuroscience
β-adrenergic receptors (β-ARs) play a critical role in modulating learning, memory, emotionality, and long-term synaptic plasticity. Recent studies indicate that β-ARs are necessary for long-term potentiation (LTP) induction in the ventral hippocampus ...

Cell type boundaries organize plant development

eLife, 2017
In plants the dorsoventral boundary of leaves defines an axis of symmetry through the centre of the organ separating the top (dorsal) and bottom (ventral) tissues.

Dorsoventral regulation of photosynthetic functions related to morphological and anatomical structures in field-grown sorghum

Photosynthetica, 2019
The rapid dorsoventral regulation of photosynthesis is important because the light conditions around both surfaces of field-grown leaves vary considerably.

Foxp1 and lhx1 coordinate motor neuron migration with axon trajectory choice by gating Reelin signalling. [PDF]

, 2010
Topographic neuronal maps arise as a consequence of axon trajectory choice correlated with the localisation of neuronal soma, but the identity of the pathways coordinating these processes is unknown.

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

Development, 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 ...

Complementary Sensory and Associative Microcircuitry in Primary Olfactory Cortex [PDF]

, 2011
The three-layered primary olfactory (piriform) cortex is the largest component of the olfactory cortex. Sensory and intracortical inputs converge on principal cells in the anterior piriform cortex (aPC).Wecharacterize organization principles of the ...

Cryptic complexity in felid vertebral evolution: shape differentiation and allometry of the axial skeleton [PDF]

, 2016
Members of the mammalian family Felidae (extant and extinct cats) are grossly phenotypically similar, but display a 300-fold range in body size, from less than 1 kg to more than 300 kg.

Elaboration of bilateral symmetry across Knautia macedonica capitula related to changes in ventral petal expression of CYCLOIDEA-like genes

EvoDevo, 2016
Background Shifts in floral form across angiosperms, particularly from radially symmetrical to bilaterally symmetrical flowers, are often associated with shifts in speciation rates and changes in pollination syndrome.

Linear signaling in the Toll-Dorsal pathway of Drosophila: activated Pelle kinase specifies all threshold outputs of gene expression while the bHLH protein Twist specifies a subset [PDF]

, 2002
Differential activation of the Toll receptor leads to the formation of a broad Dorsal nuclear gradient that specifies at least three patterning thresholds of gene activity along the dorsoventral axis of precellular embryos.

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

Advanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.
