Unveiling the Origin of Brain Waves in Disorders of Consciousness

Researchers from the Human Brain Project have identified the origin of characteristic brain waves associated with disorders of consciousness (DoC) by coupling measurements of brain waves with glucose usage in specific brain areas. The study reveals the role of subcortical areas in driving cortical activity associated with consciousness and highlights the importance of understanding the electro-metabolism of the brain for better diagnosis and treatment of DoC.

Unveiling the Neural Circuits Behind Consciousness Loss

A brain imaging study has identified two neural circuits crucial for consciousness by studying patients with disorders of consciousness and healthy volunteers. The researchers used functional magnetic resonance imaging (fMRI) to observe how external perturbations propagate through the brain in different states of reduced consciousness. They found that patients with disorders of consciousness had malfunctioning neural circuits that failed to convey and integrate information properly, leading to a lack of consciousness. In healthy individuals, specific brain regions were responsible for broadcasting and receiving information, while in patients with unresponsive wakefulness syndrome, the brain's ability to transmit and integrate information was severely impaired. The study provides insights into the mechanisms behind consciousness and could help improve treatment for patients with disorders of consciousness.

Revolutionary Method Discovered to Determine True Coma State

A new study shows that smells can help determine the best treatment for patients in comas, vegetative states, or minimally conscious states, collectively known as disorders of consciousness (DoC). Tests involving 28 patients in various levels of consciousness were carried out by a team from the Southern Medical University in China. Different odors, including vanillin and decanoic acid, were tried in the experiments, while electroencephalogram (EEG) scans were used to monitor brain activity. A higher level of consciousness tended to mean more of a response to the smells. The olfactory response may help in the assessment of consciousness and may contribute to therapeutic orientation.
