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 willpower, 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.
The average Canadian adult consumes more than triple the daily limit of 25g added sugar recommended by the World Health Organization.
Sugar triggers dopamine "hits" in the brain, making us crave more of it. Sugar also disrupts memory formation.

Children between 12 and 16 years old with mild-to-moderate hearing loss showed differences in their brain responses.

One day we will have a science of consciousness, but it won’t be science as we know it today
Optical illusions use colour, pictures and shapes that can make our brain and eyes confused.
Sometimes our brain gets confused and misunderstands what the eyes tell it.
A scientist explains how the brain works, for younger readers.
Forming and recalling memories is a complex system of synchronisation and desynchronisation in different parts the brain.

Researchers have discovered that the hippocampus and neocortex work together.
We are in a battle for our minds. And it isn't clear we will win.

These tiny nanoparticles might provide a new way to see what's happening in the brain and even deliver treatments to specific cells – if researchers figure out how to use them safely and effectively.
You might be daydreaming, but your brain is hard at work.
Your brain balances messages coming from lots of different places to help you see, imagine, remember and dream.
Your brain is conducting multiple orchestras of information at the same time.
Like a cocktail partygoer able to focus on one discussion in a noisy room, brains are able to make reliable connections against a busy neural background. Here are two phenomena that help it happen.

Ultra-clear maps of individual toes were found in the brains of two foot painters – these are not found in typically developed humans.
Got motion sickness? You're not alone in the animal kingdom.
Researchers have developed implants small enough to fit inside brain cells.
Sleep paralysis is when you wake up but feel like you can’t move.
Sleep paralysis – when you wake up but feel like you can't move – seems to be more common if you sleep on your back. But we don't know why.

From Strictly Come Dancing to the Tour de France 'curses' have rational explanations. Here, psychologists discuss why belief in them persists.
10% of people are left-handed but we still haven't uncovered how this changes the way their brains work.
