Urdu“When you’re deciding whether to turn left or right, or to eat the chocolate cake or the carrots, what’s happening in your brain?”
This simple question masks a complex web of brain activity. Computational neuroscientists are determined to untangle the web.

Clinical neurophysiology training in epilepsy: The present and the future
EEG training varies across the globe; in many countries, there is no training. Dr. Bruna Nucera talks with Dr. Sandor Beniczky about the present and future of clinical neurophysiology training.
Advanced brain imaging study hints at how DMT psychedelic alters perception of reality
In a study at Imperial College London, detailed brain imaging data from 20 healthy volunteers revealed how the potent psychedelic compound, DMT (dimethyltryptamine), alters brain function.
Bleak Cyborg Future from Brain-Computer Interfaces if We’re Not Careful
The most promising method to achieve real-world BCI applications is through electroencephalography, a method of monitoring the brain’s electrical activity. EEG-based BCIs will require a number of technological advances prior to widespread use, but more importantly, they will raise a variety of social, ethical, and legal concerns. Researchers conducted a review of modern commercial brain-computer interface devices and discuss the primary technological limitations and humanitarian concerns of these devices in APL Bioengineering.
New imaging method tracks brain’s elusive networks
Understanding the source and network of signals as the brain functions is a central goal of brain research. Now, Carnegie Mellon engineers have created a system for high-density EEG imaging of the origin and path of normal and abnormal brain signals.
Older children’s brains respond differently to rewarding versus negative experiences later in the day
Older children respond more strongly to rewarding experiences and less strongly to negative experiences later in the day, which may lead to poor decision-making at night, according to research from Binghamton University, State University of New York.
Time of day differences in neural reward responsiveness in children
The Reward Positivity (∆RewP) event-related potential (ERP), generally quantified as the difference between neural responsiveness to monetary gains (RewP-Gain) and losses (RewP-Loss) is commonly used as an index of neural reward responsiveness. Despite the popularity of this ERP component in…
