Frontiers | Bayesian network analysis revealed the connectivity difference of the default mode network from the resting-state to task-state | Frontiers in Computational Neuroscience

Functional magnetic resonance imaging (fMRI) studies have converged to reveal the default mode network (DMN), a constellation of regions that display co-activation during resting-state but co-deactivation during attention-demanding tasks in the brain. Here, we employed a Bayesian network (BN) analysis method to construct a directed effective connectivity model of the DMN and compared the organizational architecture and interregional directed connections under both resting-state and task-state. The analysis results indicated that the DMN was consistently organized into two closely interacting subsystems in both resting-state and task-state. The directed connections between DMN regions changed significantly from the resting-state to task-state condition. These results suggest that the DMN intrinsically maintains a relatively stable structure whether at rest or performing tasks but has different information processing mechanisms under varied states.

Emanuela Russo's curator insight, September 27, 2:56 PM

Una nuova ricerca evidenzia che l'uso intensivo di benzodiazepine, utilizzate per trattare ansia e disturbi del sonno, potrebbe avere una relazione con la manifestazione dell'Alzheimer nelle persone anziane.

Le benzodiazepine, a lungo andare, possono compromettere le facoltà mentali e indebolire la memoria a causa della loro interazione con alcuni recettori a livello dei circuiti cerebrali.

Sebbene non sia tuttora riconosciuta una causalità specifica tra l'uso delle benzodiazepine e la malattia di Alzheimer, si raccomanda ovviamente di non abusare di tali medicinali, specialmente per lunghi periodi nella vita. Sarebbe invece consigliabile associare all'utilizzo dei farmaci anche un percorso terapeutico che miri a rintracciare le cause del malessere e non ad arginare solamente i sintomi.

Brain to Brain Communication Using EEG Waves and the Internet

Brain to Brain Communication Using EEG Waves and the Internet | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Brain-to-brain communication was achieved recently using brain-computer interfaces, computer-brain interfaces, electroencephalographic (EEG) recordings and the internet. The developers of this brain-to-brain communication system demonstrated the transmission of information between conscious human brains without use of motor or peripheral sensory systems. This means that the information was sent from one mind to another mind without talking […]

Sensory Processing Disorders Have Biological Basis

Sensory Processing Disorders Have Biological Basis | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Sensory processing disorders (SPD) are more prevalent in children than autism and as common as attention deficit hyperactivity disorder, yet it receives far less attention partly because it’s never been recognized as a distinct disease. In a new study, researchers have shown for the first time a biological basis for the disease that sets it apart from other neurodevelopmental disorders.

In a battle of brains, bigger isn't always better: Rats and mice perform similarly in cognitive tests

In a battle of brains, bigger isn't always better: Rats and mice perform similarly in cognitive tests | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
It's one of those ideas that seems to make perfect sense: the bigger the brain, the more intelligent the creature. Exceptions are becoming increasingly common, yet the belief persists even among scientists. Most biologists, for example, assume that rats are smarter than mice. Scientists now challenge this belief. They compared mice and rats and found very similar levels of intelligence, a result that could have powerful implications for researchers studying complex behaviors and learning.
