The loss of neurons leads to degeneration.
Knowing what cells are more vulnerable could some day help researchers know why these cells are more vulnerable than others.
Rise and shine!

The mystery of how the brain creates consciousness still puzzles scientists, but the mechanics of waking up are starting to be understood.
The protein, called GDF5, plays an important role in the development and function of certain brain neurons.
Neurotrophic factors play an important role in protecting neurons – which is why researchers are investigating them as a treatment for Parkinson's.
Brainlike computer chips promise powerful computers that use little energy.

Artificial brains are far in the future, but computer chips that work like brains could keep computers advancing when today's silicon transistor chips reach their limit.

Decades of research have shown that the brain does not yield its secrets easily.
Medical treatments involving neurostimulation, or cerebral electromagnetic stimulation, are resurfacing and appear to be more effective than drugs for treating depression.

Amyotrophic lateral sclerosis, Lou Gehrig's disease, is a crippling, progressive neurodegenerative disease for which there is no cure. Now it seems that a diabetes drug may help some cases.
Scientists are still piecing together the puzzle of how the brain works.

A bioengineer explains how a clearer picture of brain structure and function may fine-tune the ways brain surgery attempts to correct structure and medication tries to correct function.
Our brains communicate information in a manner that can be likened to an air traffic controller.
Air traffic controllers have to process and manage large amounts of information to get airplanes to their destinations. The brain manages the incessant traffic of neurons in a similar fashion.
When you sniff a particular scent, your brain cells fire in a recognizable pattern.

Brains recognize a smell based on which cells fire, in what order – the same way you recognize a song based on its pattern of notes. How much can you change the 'tune' and still know the smell?
The video-sharing platform may connect to our innate mental systems for physically copying one another
The internet is awash with videos that claim to use 'binaural beats' to improve your focus or relieve stress. But while they can influence your brain, the touted mood-enhancing effects may not be.
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.
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.
We knew people with Parkinson’s disease were at heightened risk of developing addictive behaviours like gambling. Our research gives insight into why this is.
About one in six people who take the most common medication for Parkinson's disease will develop addictive behaviours. We found whether this happens depends on a person's unique brain structure.
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.
Outside Earth’s protective atmosphere, there is nothing to shield astronauts from the dangerous cosmic radiation of space.
Space missions are dangerous. But when it comes to long missions, radiation may be the greatest threat to astronauts' health.
Existing BMIs focus on restoring function for people with mobility or communication issues.

BMIs like the ones Neuralink is working on are already used in laboratories around the world as assistive technologies. But melding your mind with an AI is probably not happening anytime soon.

A new technology has enabled neuroscientists to examine the chemistry of individual brain cells. The finding reveal how genes are regulated differently in brain cells of people with autism compared to neurotypical people.
Your brain is about 70% water.
An adult brain weighs about 1.5kg. It's mostly water with some fat, protein, sugar and a dash of salt. Sounds like pancakes, I know, but I once tried chicken brains and, well, pancakes are tastier.
