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…

DeepBach: Listens to Bach music and writes new one in the same style

Sony Corporation developed a model of polyphonic music generation, which learns to compose chorales in the style of Bach.  This model is capable of producing convincing chorales, even if it is trained with no other data that the 400 chorale sheets by Bach. A key feature is that they are able to constrain the generated chorales in…

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…

Understanding the Fourier transform

The Fourier transform is a mathematical technique that allows an MR signal to be decomposed into a sum of sine waves of different frequencies, phases, and amplitudes. This remarkable result derives from the work of Jean-Baptiste Joseph Fourier (1768-1830), a French mathematician and physicist.  Since spatial encoding in MR imaging involves frequencies and phases, it…

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…

New BCI might give back the world to locked-in syndrome patients

Researchers have been using brain-computer interfaces (BCIs) to interact with patients suffering from locked-in syndrome for the last decade. What is brand-new is a system created by the Wyss Center for Bio and Neuroengineering in Switzerland that may finally allow even the most paralyzed patients communicate and create a new channel of communication with the outside…

Brain network connectivity behind speech disorder

Research on the hidden patterns of brain activity needed to produce speech is giving scientists fresh insights into what goes wrong in various speech disorders. Speaking is one of the most complex human cognition processes the brain controls. Speech depends on the precise coordination of more than 100 muscles (spread across the mouth, lungs and…

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…

Exploring the Art hidden in Pi

Since 2013, scientist and data graphics guru Martin Krzywinski, who is both a scientist and data artist, has been celebrating “Pi Day” by visualizing the outstanding mathematical value in original and fascinating ways. This year, inspired by the recent announcement of the discovery of gravitational waves by LIGO scientists, Martin has dropped a complex new…

ASCII to EDF format converter

The Approach The main goal of this post is to explain how to convert OpenBCI datasets in EDF format files in a simple, easy and straightforward way. Many researchers and programmers have shared their files and software, either on an individual basis or in the framework of a larger group or project. In the name…
