Enhancement of semantic integration reasoning by tRNS

Cognitive, Affective and Behavioral Neuroscience, 2021
The right hemisphere is involved with the integrative processes necessary to achieve global coherence during reasoning and discourse processing. Specifically, the right temporal lobe has been proven to facilitate the processing of distant associate relationships, such as generating novel ideas.

tRNS boosts perceptual learning in peripheral vision

Neuropsychologia, 2019
Visual crowding, the difficulty of recognizing elements when surrounded by similar items, is a widely studied perceptual phenomenon and a trademark characteristic of peripheral vision. Perceptual Learning (PL) has been shown to reduce crowding, although a large number of sessions is required to observe significant improvements.

tRNS effects on visual contrast detection

Neuroscience Letters, 2020
In recent years, transcranial electrical stimulation (tES) has been used to improve cognitive and perceptual abilities and to boost learning. In the visual domain, transcranial random noise stimulation (tRNS), a type of tES in which electric current is randomly alternating in between two electrodes at high frequency, has shown potential in inducing ...

The effects on tACS and tRNS on language function: A literature review

Brain and Language
Transcranial electrical stimulation (tES) techniques are promising noninvasive tools for modulating language-related neural processes. While transcranial direct current stimulation (tDCS) has been well studied, transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS) remain less characterized.

Transcranial electrical stimulation (tES – tDCS; tRNS, tACS) methods

Neuropsychological Rehabilitation, 2011
Weak transcranial direct current stimulation (tDCS) with a homogenous DC field at intensities of around 1 mA induces long-lasting changes in the brain. tDCS can be used to manipulate brain excitability via membrane polarisation: cathodal stimulation hyperpolarises, while anodal stimulation depolarises the resting membrane potential, whereby the induced

Phylogenetic split of Larix : evidence from paternally inherited cpDNA trn T- trn F region

Plant Systematics and Evolution, 2003
A molecular phylogeny of Larix comprising 12 species was constructed from the sequence analysis of the paternally inherited cpDNA trnT-trnF region of 46 individuals. The most parsimonious tree split Larix into three sister clades: one clade was composed of two North American species, the other two were short-bracted and long-bracted species of Eurasia ...

Deletions in the plastid trn T- trn L intergenic spacer define clades within Cactaceae subfamily Cactoideae

Plant Systematics and Evolution, 2002
The phylogenetic distribution of two deletions, of about 350 and 250 bp respectively, within the chloroplast trnT–trnL intergenic spacer was examined. One deletion was found in all members of Cactaceae subfamily Cactoideae sampled, totaling 37 species, but not in taxa from other subfamilies or closely related families. The second was shared by a subset

Extending the TRN model in a biologically plausible way

1997
The Topology Representing Network (TRN) model is extended by using an activation dynamics which implicitly orders the neurons according to the distance from the input pattern. This allows to apply the same Hebbian learning method to the thalamo-cortical and cortico-cortical connections.

TRN history, trends and the unused potential

2012 IEEE/AIAA 31st Digital Avionics Systems Conference (DASC), 2012
The term Terrain Referenced Navigation is used to describe a larger family of systems that estimate position by measuring terrain heights and comparing them with a digital elevation map. This is not a new navigation technique. In fact, TRN has been around for some time, with its history dating back to the 1950s.
