Help your child say yes!

Watch out for the challenge: one, two, three and… Don’t think of a pink elephant! Did you get it? I doubt it very much. The reason for a chubby pink elephant automatically appearing in your mind is the same reason why young children have difficulty obeying various “no’s”: the brain automatically activates its representations of […]

The problem with saying no

The intention is the best possible: to prevent them from being run over, destroying the house, taking what isn’t theirs, falling off the wall or killing the cat. You say “don’t put your hand there!” – but your child does anyway. Why is it so difficult to get a child to obey no?   Asterix […]

Adolescence is a brain thing

Pick a book about the brain at random and you’ll probably read that most of the brain’s transformations take place during the first three years of life – or, with good grace, the first ten. After that… chaos: with the brain supposedly ready, adolescence would be that phase of life where everything would be fine […]

07. Actions potentials spread like wildfire – I mean, electricity

Before you begin, ask yourself: Do you remember what an "action potential" is? How do you define it? What spreads faster, electricity or molecules? How come?

13. Associate networks make behaviors flexible

Before you begin, ask yourself: How can your behavior be so much more than simply responding to stimuli? Can you think of examples of how your behavior is flexible and complex? At this point, how do you imagine that your brain makes it so?

04. Neuronal activity is loss of cell charge

Before you begin, ask yourself: What comes to mind when you hear the expression "neuronal activity"? That is, what are neurons doing when they are "active"?

02. Nervous systems are loops within the body

Before you begin, ask yourself: What does the word "loop" mean to you? How would you define "nervous system", and what does it do? What do you think is a "nerve"? Do you think sensations beget actions; actions beget sensations; both; neither?
