Dynamic encoding of natural luminance sequences by LGN bursts [PDF]

open access: yes, 2006
In the lateral geniculate nucleus (LGN) of the thalamus, visual stimulation produces two distinct types of responses known as tonic and burst. Due to the dynamics of the T-type Ca2+ channels involved in burst generation, the type of response evoked by a ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

A Plan Tonic növénykondicionáló szer hatásának vizsgálata őszi búza, napraforgó, szója és cukorrépa kultúrákban

open access: yes, 2022
Mivel a világ népességszámának drasztikus növekedésének eredményeként egyre nagyobb problémát jelent az emberek élelmiszerrel történő ellátása, a hatékony mezőgazdasági termelésre a korábbiaknál is nagyobb szükség van. Előtérbe kerülnek azok a módszerek,

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Tonic Pupil Following Traumatic Hyphema: Case Report

open access: yes, 2013
A 7-year-old girl was admitted to our clinic after crash injury with air gun pellet in her right eye. There was an intense anterior chamber reaction and hyphema on the biomicroscopic examination. During the control examination after treatment of hyphema

Automatic tonic identification in Indian art music: approaches and evaluation

open access: yes, 2014
The tonic is a fundamental concept in Indian art music. It is the base pitch, which an artist chooses in order to construct the melodies during a rāg(a) rendition, and all accompanying instruments are tuned using the tonic pitch.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Cognitive, neuroimaging, and genetic insights on the interthalamic adhesion from a large cohort study of 591 subjects

open access: yesScientific Reports
Both thalami can be connected by the Interthalamic Adhesion (IA), a white matter tract that crosses the 3rd ventricle. Its presence varies among individuals and remains poorly understood.

Differential energetic profile of signal processing in central vestibular neurons

open access: yesFrontiers in Neurology
BackgroundEnergetic aspects of neuronal activity have become a major focus of interest given the fact that the brain among all organs dominates the oxygen consumption. At variance with the importance of neuroenergetics, the knowledge about how electrical
