Neural signatures of α2-Adrenergic agonist-induced unconsciousness and awakening by antagonist

open access: yeseLife, 2020
How the brain dynamics change during anesthetic-induced altered states of consciousness is not completely understood. The α2-adrenergic agonists are unique.

Unseen Monsters: The Horla by Guy de Maupassant [PDF]

open access: yesActa Iassyensia Comparationis, 2022
As fear is a common trope that dominates the Gothic genre, it embodies subconscious manifestations of anxieties, relationships, and beliefs. There is a resistance against the simplification of fear, as the intimate workings of the mind provide a unique ...

Theta phase coherence in visual mismatch responses involved in access processing to visual awareness

open access: yesFrontiers in Human Neuroscience, 2023
Introduction: The electroencephalographic brain response to a deviation from the preceding sequential regularity of visual events, called visual mismatch negativity (vMMN), is well known to reflect automatic visual change detection. Our preliminary study

Archetypal Analysis of "Almalek and Albrahmh” from Kalila va Demna [PDF]

open access: yesمتن شناسی ادب فارسی, 2016
Archetype Theory, has been raised from Carl Gustav Young’s Psychoanalytical School. Young knows mental images and Sediments and Hereditary information which there are in the collective unconscious as Archetype. In other word, archetype is general type of

Validation of behavioural indicators used to assess unconsciousness in sheep

open access: yes, 2015
The validity of behavioural indicators to assess unconsciousness under different slaughter conditions is under (inter)national debate. The aim of this study was to validate eyelid-, withdrawal-, threat reflex and rhythmic breathing as indicators to ...

Top-down mechanisms of anesthetic-induced unconsciousness [PDF]

open access: yes, 2014
The question of how structurally and pharmacologically diverse general anesthetics disrupt consciousness has persisted since the 19th century. There has traditionally been a significant focus on bottom-up mechanisms of anesthetic action, in terms of ...

Electroencephalogram signatures of ketamine anesthesia-induced unconsciousness

open access: yes, 2017
Objectives: Ketamine is an N-methyl-. d-aspartate (NMDA) receptor antagonist commonly administered as a general anesthetic. However, neural circuit mechanisms to explain ketamine anesthesia-induced unconsciousness in humans are yet to be clearly defined.

Alternatives to Carbon Dioxide in Two Phases for the Improvement of Broiler Chickens’ Welfare during Stunning

open access: yesAnimals
This study evaluated the exposure to gas mixtures of carbon dioxide (CO2) associated with nitrogen (N2) as alternatives to CO2 in two phases to improve the welfare of broiler chickens at slaughter. Broilers were exposed to one of three treatments: 40C90C

Propofol and Sevoflurane Differentially Modulate Cortical Depolarization following Electric Stimulation of the Ventrobasal Thalamus

open access: yesFrontiers in Computational Neuroscience, 2017
The neuronal mechanisms how anesthetics lead to loss of consciousness are unclear. Thalamocortical interactions are crucially involved in conscious perception; hence the thalamocortical network might be a promising target for anesthetic modulation of ...
