Binaural Beats as Brain Enhancers: is there any Scientific Proof?

Maybe you have heard of binaural beats, a soundwave stimulus that has spread across the internet for having positive effects on mood and cognition. Binaural beats are auditory illusions that occur when presenting two tones with a slight frequency mismatch to each ear separately. Some evidence support that such acoustic stimulation can train the brain signals, altering both, specific brainwaves and connectivity patterns. Other evidence indicates just placebo effects suggesting no better benefits than monoaural beat stimuli. Today, the assumed exceptional effects of binaural beats on human emotion and cognition remain still unclear. Regardless of such discrepancies, what is the scientific evidence of its claimed effects on the human brain?

Neurotechnology: where we are and where we are going?

brain-hack

Today,  advance “brain-reading” technology makes increasingly possible to access an individual’s mental activiy. Although it may sound a bit scary, the reality is that scientists from different  fields are already working with sophisticated technologies to “decipher” the bases human thoughts in real-time. Control a computer, move an artificial arm, or obtain knowledge of individuals´ mood and thoughts are just few examples of the advances of neurotechnology. Very recently last summer, Tesla founder Elon Musk, presented to the big public an implantable brain device capable of reading users’ minds. 

One interesting question is why “mind-reading” technology could be necessary for our lives? Leaving aside ethical issues, should we worry if modern neurotechnology can figure out what we are thinking? Continue reading “Neurotechnology: where we are and where we are going?”

Exploring the brain correlates of emotions in babies

One of the most interesting topics in the field of emotional development research relates to infants´ capacity to express and experience different emotional states. A general question refers to when emotions first emerge in humans life.  Approach and withdrawal are two important concepts in the definition of human´s emotions. Both constructs have not typically been viewed as features of infant emotional behavior until late in the first year. However, when looking directly into infants´ brain, researchers have found a different story suggesting that infants experience positive and negative emotions from birth but in a very basic way and not as adults do.

Infants´ emotions are not equivalent to adults emotions
