How the brain acquires language is a topic that has been of interest to researchers over the last few decades. Native level language proficiency has been attributed to the critical period after which one does not reach native-level proficiency. This is because the brain wires as per the regularities of…


Children spend a predominant amount of time during their early to mid-teen years in schools, a place that educates them and prepares them for the real world. Apart from this, schools ought to provide environments that are stimulating and dynamic for the development of an individual. A fundamental requirement is…


Human beings are loss averse. Losing something hurts us way more than the pleasure of gaining the same thing. This is why we’d rather hold on to something even when there are possibilities of gains if we let go. This is also exactly why we value something we own a…


Learning occurs at all stages of a lifetime. New skills are picked up by adults, just as they are by children. Thus, experience-dependent changes are persistent at all stages in life. Let us now zoom in to the molecular basis of this learning.

With frequent and strong correlated activation of…


Neuroplasticity is the ability of the brain to structurally and functionally re-organize itself. Earlier, it was predominantly believed that it is an ability restricted to a critical period in early childhood after which the connections are fixed and so are our abilities. Now we know that the brain’s plasticity does…


When we say that experience shapes our brain’s circuitry, a fundamental question to ask is ‘what kind of experiences?’ A very simple answer is that experience relevant to us renders our neural networks in a heightened state of plasticity. Every time a stimulus is meaningful to us, we attend to…


Experience-dependent brain development

The last several decades have seen numerous debates on the extent of genetically determined neural circuitry and experience-dependent modifications. In this argument, the period in which the brain is most influenced by the environment, also known as the critical period, is highly talked about given the inconclusive…


Altering memories!

The almond-shaped region of the brain called the amygdala fired hysterically as she entered the dark simulation room. Following this, her heart started beating rapidly and she began to sweat profusely. Nyctophobia, that is the fear of darkness that had gripped her as a child continued through her…


Distractibility — a boon or bane for memory encoding

Our life would be far more productive and useful if we could focus on a particular task and get it done without any distractions, isn’t it? We generally hear teachers tell their students, “ Don’t get distracted. Pay attention to your…


Throughout our evolutionary history, it became crucial to go beyond what was perceptually available, for the sake of our survival. To do it, we needed to evoke the previous experiences we had interacting with the world, by default. Concepts helped us easily access these numerous experiences. Concepts can be defined…
