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….

The left/right brain myth

The origins of the myth The left/right brain myth holds that a right-brain dominant person is generally creative, intuitive, artsy, while a left-brain dominant person is more of a problem-solver, more linear, logical. The myth arose from genuine science, but new imaging technology has shown that the brain is more interdependent than once thought. The…

How does mindfulness meditation change the brain?

What is mindfulness meditation? Meditation can be defined as a form of mental training that aims to improve an individual’s core psychological capacities, such as attentional and emotional self-regulation. Meditation encompasses a family of complex practices that include mindfulness meditation, mantra meditation, yoga, tai-chi and chi-gong. Of these practices, mindfulness meditation – often described as non-judgemental attention to present-moment experiences – has received most attention…

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 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…

A newly updated map of the human brain shows almost 100 areas

A newly updated map of the human brain may be the most accurate yet, helping solve over 100 years of arguments and showing nearly 100 areas that hadn’t been reported before. The first hints of the brain’s hidden geography emerged more than 150 years ago. In the 1860s, the physician Pierre Paul Broca was intrigued…

How the Brain Builds Memory Chains

Do you remember the first time you met your college classmate? You were probably nervous, talking a little too loudly and laughing a little too heartily. What else does that memory bring to mind? The lunch you shared later? The other classmates you met that night? Memories bring about memories, and as soon as you…

Introduction to Mu Waves

Brain-Computer Interfaces (BCI) are currently being pursued in several approaches by different researchers and people around the World. One approach is to measure the “Mu Rhythms”, or also known as “Mu Waves” from the sensorimotor area of one’s brain by registering an EEG signal. The Mu Waves are associated with the movement of the body –…
