Herinneren van een gebeurtenis verandert je geheugen | Peter Moleman

The memory develops after birth. A baby starts by registering how it should move. From around the age of three, a child can register events which form part of its life story, to be recalled in later life. But emotional events such as traumas are possibly registered much earlier as stray facts. These can elicit reactions, although you can’t retell them.

Verbazingwekkend en paradoxaal | Peter Moleman

The Corona virus spreads via coughing and sneezing. The way it spreads should be easy to investigate. But that does not turn out to be true. Scientists only know a fraction of what they want to know and have to deliver facts to the authorities in order for them to act swiftly. Our Dutch scientists are top of the bill. Therefore, I have confidence in them.

Groeien en snoeien: de hersenen van een kind

A newborn baby cannot speak, it sees almost nothing, and controlled movements of its arms and legs are minimal. From birth onwards, however, rapid learning occurs associated with significant changes in the brain, which are both cause and effect of this learning process.

Het Ego is dood, lang leve het ego | Peter Moleman

The Ego does not exist, it is an illusion, a trick of the brain. This claim of neuroscientists may scare you. But is it true? Or does something like an ego exist? And if so, what is it?

I can’t recall your name, am I getting dementia?

Peter Moleman27/02/2020Articles, Memory, PsychiatryLeave a Comment

I am not good at recalling names, and never have been. Is my brain not working as well as it did? Is it dementia? Or does everyone have weaknesses that get progressively worse as you age?

Autisme is erfelijk, maar je erft geen autisme | Peter Moleman

The probability of having autism is greater for an individual if it runs in their family. This suggests hereditary factors. But what do you actually inherit? What you inherit is a predisposition for a specific development of your brain. This, together with what you experience while growing up, can lead to the development of a mild to severe form of autism.

Letters and messages, neurons and thoughts

Peter Moleman28/11/2019Articles, Parts and the wholeLeave a Comment

Is a thought simply the sum total of the activity of all the neurons in the brain? No, just as a message is not simply the placement of a sequence of letters which follow the rules of grammar. How do those letters stand in relation to that message? How does the activity of neurons stand in relation to a thought? Was Descartes right, or are we our brain?

Het zonlicht komt van boven | Peter Moleman

How would we manage, if we could not visualise three-dimensional objects from flat two-dimensional diagrams? An amazing feat our brain performs. What role does pre-determined programming play in this? That is related to how the sun shines on us.

Hallucinations: seeing what you expect

Peter Moleman31/10/2019Articles, Psychiatry6 Comments

Someone who is hallucinating will see things, whole scenes and events which are not actually there, and experience them as real.How can this be? Because you see what you expect, unless it is corrected by your perceptions. Which is where things can go wrong.

De parabel van het brein dat een moord pleegde | Peter Moleman

In a country with golden sand dunes by the sea, each year saw more murders committed than the year before. Neuroscientists had proven that the murderer’s brain made him commit the murder. The judges were stuck. How could they solve this problem?
