The importance of phase in EEG-based Brain-Computer Interfaces

In the world that we live, we have to react to sensory inputs all the time: the hustle and bustle of the city (traffic lights, cars, bikes…), notifications popping up in our screen, concerts… Taking the traffic light as an example, has ever happened to you that when you are waiting to cross and the…

A taxonomy of attention

In 1890, William James famously declared in The Principles of Psychology that “Everyone knows what attention is”. Attention has become a catch-all term for how the brain processes its own information, and its effects can be measured through behaviors, electrophysiology, and brain imaging methods. However, attention is so ubiquitous and has such multiple forms that it is…

How human memory works?

Memory is essential to all our lives. Without a memory of the past, we could not operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done today or what we plan to do tomorrow. Without memory, we could not learn anything….

How to practice effectively for just about anything

Mastering any physical skill takes practice. Practice is the repetition of an action with the goal of improvement, and it helps us perform with more ease, speed, and confidence. But what does practice actually do to make us better at things? Annie Bosler and Don Greene explain how practice affects the inner workings of our…

How good is your gut number sense?

How good is your gut number sense? Have you ever tried to guess how many jelly beans are in a jar? Or “guesstimated” the number of people who were at the concert last night? Number sense is your intuitive recognition of numbers and their relationships. You can tell, for instance, that one group of circles…

Lust, Romance, Attachment – What brain scanning says about the drive to love

Scientists have their own models of love and attraction, formed independently and through different methods. Though there are likely many models, I will stick to the model of love defined by Helen Fisher. Helen E. Fisher, PhD biological anthropologist, is a Senior Research Fellow, at The Kinsey Institute, Indiana University, and a Member of the…

Brain signals, a new biometric identification

Fingerprint scanning, iris scanning, and voice stress analyzer are dated technology compared to the latest form of biometric authentication: the brain’s semantic memory. A team led by postdoctoral researcher Blair Armstrong of the Basque Center for Cognition, Brain, and Language in Spain, observed that the brain signals of 45 participants reading a list of 75…

Semantic maps in the human brain

The meaning of language is represented in regions of the cerebral cortex known collectively as the “semantic system”. However, little of the semantic system has been mapped comprehensively, and the semantic selectivity of most regions is still unknown. Here we systematically map semantic selectivity across the cerebral cortex using voxel-wise modeling of fMRI data collected…

Visualizing the Global Network of Languages

Interactive nodal network diagrams can offer some of the most well-supplied data exploration opportunities in the  world of data graphics. The Macro Connections Group at MIT Media Lab released Global Language Network, an interactive visualization of the relationships among the world’s many languages. This colorful web of information represents an ideal use of the nodal diagram as…
