Distillation of Regional Activity Reveals Hidden Content of Neural Information in Visual Processing

open access: yesFrontiers in Human Neuroscience, 2021
Multivoxel pattern analysis (MVPA) has become a standard tool for decoding mental states from brain activity patterns. Recent studies have demonstrated that MVPA can be applied to decode activity patterns of a certain region from those of the other ...

Pre-integration lateral inhibition enhances unsupervised learning [PDF]

open access: yes, 2002
A large and influential class of neural network architectures use post-integration lateral inhibition as a mechanism for competition. We argue that these algorithms are computationally deficient in that they fail to generate, or learn, appropriate ...

Linking Cellular Mechanisms to Behavior: Entorhinal Persistent Spiking and Membrane Potential Oscillations May Underlie Path Integration, Grid Cell Firing, and Episodic Memory [PDF]

open access: yes, 2008
The entorhinal cortex plays an important role in spatial memory and episodic memory functions. These functions may result from cellular mechanisms for integration of the afferent input to entorhinal cortex.

Vestibular Morphological Asymmetry Associated With Motion Sickness Susceptibility

open access: yesFrontiers in Neuroscience, 2021
Sensory conflicts leading to motion sickness can occur not only between but also within sensory modalities. The vestibular organs are located in both left and right inner ears, and their misalignment can be a source of self-motion related sensory ...

MicroRNA29a regulates IL-33-mediated tissue remodelling in tendon disease [PDF]

open access: yes, 2015
MicroRNA (miRNA) has the potential for cross-regulation and functional integration of discrete biological processes during complex physiological events.

Phenotypic Plasticity in Sexual Reproduction Based on Nutrients Supplied From Vegetative Ramets in a Leymus chinensis Population

open access: yesFrontiers in Plant Science, 2020
Phenotypic plasticity is considered a major mechanism that allows plants to adapt to heterogeneous environments. The physiological integration between the interconnected rhizomes or stolons of clonal plants influences the plasticity of such plants in ...

Developmentally Programmed Division of Labor in the Aquatic Invader Alternanthera philoxeroides Under Homogeneous Soil Nutrients

open access: yesFrontiers in Plant Science, 2019
Clonal traits can contribute to plant invasiveness, but little is known about the roles of division of labor (a key clonal trait) in homogeneous habitats. The hypothesis tested is that clonal integration allows division of labor and increases the overall

Noninvasive vagus nerve stimulation alters neural response and physiological autonomic tone to noxious thermal challenge. [PDF]

open access: yes, 2019
The mechanisms by which noninvasive vagal nerve stimulation (nVNS) affect central and peripheral neural circuits that subserve pain and autonomic physiology are not clear, and thus remain an area of intense investigation.

Phenotypic flexibility and the evolution of organismal design [PDF]

open access: yes, 2003
Evolutionary biologists often use phenotypic differences between species and between individuals to gain an understanding of organismal design. The focus of much recent attention has been on developmental plasticity – the environmentally induced ...

Following one's heart: cardiac rhythms gate central initiation of sympathetic reflexes [PDF]

open access: yes, 2009
Central nervous processing of environmental stimuli requires integration of sensory information with ongoing autonomic control of cardiovascular function.
