Propofol Induction Reduces the Capacity for Neural Information Integration: Implications for the Mechanism of Consciousness and General Anesthesia [PDF]

open access: yes, 2008
The cognitive unbinding paradigm suggests that the synthesis of cognitive information is attenuated by general anesthesia. Here, we investigated the functional organization of brain activities in the conscious and anesthetized states, based on ...

Desflurane Selectively Suppresses Long-latency Cortical Neuronal Response to Flash in the Rat [PDF]

open access: yes, 2009
Background—The effect of inhalational anesthetics on sensory-evoked unit activity in the cerebral cortex has been controversial. Desflurane has desirable properties for in vivo neurophysiologic studies but its effect on cortical neuronal activity and ...

Connecting the P300 to the diagnosis and prognosis of unconscious patients

open access: yesNeural Regeneration Research, 2015
The residual consciousness of unconscious patients can be detected by studying the P300, a wave among event-related potentials. Previous studies have applied tones, the subject′s name and other names as stimuli. However, the results were not satisfactory.

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

On the Plausibility of Idealism: Refuting Criticisms [PDF]

open access: yes, 2017
Several alternatives vie today for recognition as the most plausible ontology, from physicalism to panpsychism. By and large, these ontologies entail that physical structures circumscribe consciousness by bearing phenomenal properties within their ...

Unconscious mental imagery [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2020
Historically, mental imagery has been defined as an experiential state—as something necessarily conscious. But most behavioural or neuroimaging experiments on mental imagery—including the most famous ones—do not actually take the conscious experience of the subject into consideration.

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

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.

Efficiency of low versus high airline pressure in stunning cattle with a pneumatically powered penetrating captive bolt gun [PDF]

open access: yes, 2017
The efficiency of stunning cattle was assessed in 443 animals (304 pure Zebu and 139 crossbred cattle), being mainly mature bulls and cows. Cattle were stunned using a Jarvis pneumatically powered penetrating captive bolt gun operating with low (160–175 ...
