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.
PsychCentral.com Neuroscientists Make Huge Strides Toward Solving the Mysteries of the ... Big Think While many parents have simply given up on trying to understand their teenagers, neuroscientists aren't ready to throw in the towel quite yet.
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.
Functional magnetic resonance imaging (fMRI) is the workhorse of imaging-based human cognitive neuroscience. The use of fMRI is ever-increasing; within the last 4 years more fMRI studies have been published than in the previous 17 years. This large body of research has mainly focused on the functional localization of condition- or stimulus-dependent changes in the blood-oxygenation-level dependent (BOLD) signal. In recent years, however, many aspects of the commonly practiced analysis frameworks and methodologies have been critically reassessed. Here we summarize these critiques, providing an overview of the major conceptual and practical deficiencies in widely used brain-mapping approaches, and exemplify some of these issues by the use of imaging data and simulations. In particular, we discuss the inherent pitfalls and shortcomings of methodologies for statistical parametric mapping. Our critique emphasizes recent reports of excessively high numbers of both false positive and false negative findings in fMRI brain mapping. We outline our view regarding the broader scientific implications of these methodological considerations and briefly discuss possible solutions.
Dysfunction in dopamine signaling profoundly changes the activity level of about 2,000 genes in the brain’s prefrontal cortex and may be an underlying cause of certain complex neuropsychiatric disorders, such as schizophrenia, according to UC Irvine scientists.
Members of the Critical Neuroscience initiative raised the question whether the perceived normative significance of neuroscience is justified by the discipline’s actual possibilities. In this paper I show how brain research was assigned the ultimate political, social, and moral authority by some leading researchers who suggested that neuroscientists should change their research priorities, promising solutions to social challenges in order to increase research funds. Discussing the two examples of cognitive enhancement and the neuroscience of (im)moral behavior I argue that there is indeed a gap between promises and expectations on the one hand and knowledge and applications on the other. However it would be premature to generalize this to the neurosciences at large, whose knowledge-producing, innovative, and economic potentials have just recently been confirmed by political and scientific decision-makers with the financial support for the Human Brain Project and the BRAIN Initiative. Finally, I discuss two explanations for the analyzed communication patterns and argue why Critical Neuroscience is necessary, but not sufficient. A more general Critical Science movement is required to improve the scientific incentive system.
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...
Stress is contagious. Observing another person in a stressful situation can be enough to make our own bodies release the stress hormone cortisol. This is the conclusion reached by scientists involved in a large-scale cooperation project between the departments of Tania Singer at the Max Planck Institute for Cognitive and Brain Sciences in Leipzig andRead More
An international group led by Vanderbilt University researchers has found cannabinoid receptors, through which marijuana exerts its effects, in a key emotional hub in the brain involved in regulating anxiety and the flight-or-fight response. This is the first time cannabinoid receptors have been identified in the central nucleus of the amygdala in a mouse model,Read More
Zoe Williams: The idea that a child's brain is irrevocably shaped in the first three years increasingly drives government policy on adoption and early childhood intervention. But does the science stand up to scrutiny?
