For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.
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.
New research by scientists at the Ottawa Heart Institute and the University of Maryland School of Medicine (UM SOM) has uncovered a new pathway by which the brain uses an unusual steroid to control blood pressure.
In Professor Idan Segev’s outstanding neuroscience MOOC , Synapses, Neurons and Brains on Coursera, students learn how electrical activity in a single nerve cell link to more sophisticated brain functions.
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 […]
Donald J Bolger's insight:
I'm not saying that this will not some day be possible, but I'll file this one with the flying car. We still drive 4-wheeled vehicles as we have a hundred years ago.
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.

When we learn, we associate a sensory experience either with other stimuli or with a certain type of behaviour. The neurons in the cerebral cortex that transmit the information modify the synaptic connections that they have with the other neurons.
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.
People make immediate judgments about images they are shown, which could impact on their decisions, even before their brains have had time to consciously process the information, a study of brainwaves led by The University Of Melbourne has found.
Montréal, August 31, 2014 – A study just published in the prestigious Nature Neuroscience journal by, Sylvain Williams, PhD, and his team, of the Research Centre of the Douglas Mental Health University Institute and McGill University, opens the...
