Faced with uncertain and anxious times, brains send out instructions to start stockpiling supplies – whether you're a person facing a pandemic, or a rodent prepping for a long winter.
It takes time for information from our eyes to reach our brains and become part of our conscious experience. So our brains use predictions to make up the delay.
It’s hard not to be scared of an invisible and spreading threat.

It can feel like everyone is stewing in anxiety about COVID-19 and seeing other people freak out can make you freak out more. A psychiatrist explains this phenomenon, and how to keep it in check.
‘Who thought that?’
The captain of a ship, or a soul, doesn't sail while ignoring the wind – sometimes they go with it, sometimes against it, but they always account for it.
Stress can make your life considerably less colourful.
Chemical changes in the brain associated with chronic stress can put our cognition and mood under serious strain.
We’re still learning about the human brain.
Even though the brain controls virtually everything we do, we often know very little about it.
A new tool for seeing hotspots in the brain could help doctors detect neurological disorders.
Understanding how the computations in the brain go wrong could help scientists develop treatments for neurological disorders.
The knowledge produced in designing and developing artificial neural networks may provide new insights into how our brains work.

We have a strong tendency to overreact emotionally and underreact behaviourally to news of infectious diseases.
Just a few millimeters across, organoids are clumps of cells that resemble the brain.

Brain organoids are tiny models that neuroscientists use to learn more about how the brain grows and works. But new research finds important differences between the model and the real thing.
Looking out the window instead might stop you feeling sick, but that doesn’t work for everyone.
When you read in the back seat of the car, your eyes tell your brain you're still. But your ears can sense you're moving. Your eyes and ears are having an argument that your brain is trying to settle.
The scientific understanding of our internal experiences is changing and it now seems likely that 'Christmas cheer' may be an emotion in itself.
Neurostimulation is rife with potential and pitfalls.
From dementia to depression to drug addiction, artificial brain stimulation has been hailed as a landmark medical technology for the future. But safeguards are needed if we want the benefits without the risks.
With the ubiquity and availability of devices connected to the internet, access to pornography is easier than it has ever been.
Cognitive neuroscience finds that regular consumption of pornography affects the centres of the brain responsible for will power, impulse control and morality.
It’s these brain cells that really make humans unique.
We have more neurons in our cortices than any other species, courtesy of an early technology – and along with them came our long, slow lives, with plenty of chances to gather around the dinner table.
Those smiles probably aren’t thanks to tryptophan.

Tryptophan, found in food, is an important ingredient in the neurotransmitter serotonin. But is that enough to support it as a possible mood booster? The research is decidedly mixed.
