Dreams are a complex phenomenon that most people experience during sleep. They are characterized by a series of thoughts, images, and emotions that are felt and recalled sometimes with high vividness. Such activity is associated with the so-called rapid eye movement (REM) sleep phase, which entails a separate phase from the no-REM (NREM) sleep cycle. Brainwave activity linked to REM sleep resembles that of the waking brain making it hard to distinguish between them. Recently, new research has found for the first time a novel brain pattern that allows predicting when someone is dreaming and even the content of dreams. In this post, you will get to know better what is going on in the brain when you dream and the purpose of dreaming.Continue reading “Dreaming: A peculiar form of cognitive activity”
Have you noticed that some of our actions or behaviors are not carried out consciously? The truth is that we are not fully aware of everything that happens inside our brain like all the connections triggered when an emotion or thought suddenly appears in our mind. Instead, we know that the major brain activity is highly driven by both, internal biological signals linked to the autonomous system and external cues coming from the environment. Apparently, all these brain activity generators are beyond our conscious control. But is this really the case?
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
