Thanks to this support, scientists created high-tech microscopes and special dyes. These let us quickly see how brain cells connect and react.1 The efforts also drew in experts from areas such as engineering and computer science. This mix has sparked a wonderful era of neuroscience.2 Soon, detailed maps of the brain will give us new insights into its complexity.2
Interdisciplinary Collaboration and Talent Integration
Artificial intelligence (AI) and neuroscience have worked hand in hand, leading to great advancements. AI programs, inspired by the brain, have helped find new truths.2 And special software has uncovered the brain’s detailed workings.2 The joining of different fields, from engineering to computer science, has truly energized brain research.2
The Brain-AI-Brain Virtuous Cycle
Neuroscience and artificial intelligence (AI) are closely connected. The cortex’s structure and how information flows in it have influenced deep learning. This is the main type of AI we use today.2
AI’s models have also learned from the brain. For example, the idea of hippocampal replay has helped improve AI. In return, AI algorithms that copy the brain are shedding light on how our brains work. They are helping answer questions about the brain, like how we see information.4
Deep Learning Inspired by Neural Networks
Now, AI is growing with insights from how our brains work. We see this in the new AI models that imitate our neural processing.2
There are also chips being made to work more like our brains. These chips can do complex tasks using less energy than regular computers.2
As AI gets better, it’s bringing neuroscientists and AI experts together. This is leading to new tools that help us understand the brain even more. We’re figuring out things about memory, decision-making, and emotions. This back-and-forth progress benefits both the AI and neuroscience worlds.2
Neuromorphic Chips and Brain-like Computing
New chips are being designed to work like our brains. They use less energy but can do complex calculations. They are a step forward for both AI and neuroscience because they work more efficiently than normal computer chips.2
AI Unveiling Intricacies of Neural Processing
AI that mimics the brain helps us understand more about our brains. It’s solving old mysteries, such as how we process what we see.4
With stronger AI and teamwork between neuroscientists and AI researchers, we expect to learn more about the brain. This includes understanding memory, decision-making, and emotions better. The help goes both ways, benefiting AI and neuroscience.2
Groundbreaking Neuroscience Discoveries of the Last Decade
The 2010s were really exciting for the field of neuroscience. Major breakthroughs have changed how we see the brain. For instance, we now have brain-computer interfaces that let paralyzed people control things with their thoughts.2
This time also saw big efforts in studying the brain. Countries around the world joined in, creating new ways to map our brains.2 The link between neuroscience and artificial intelligence became stronger.2 Plus, we began to use optogenetics and brain organoids in our research.2 These tools have opened up new possibilities in brain study.
In 2010, the thought of these advancements was almost sci-fi. Helping paralyzed folks walk or reading someone’s mind seemed far off.2 But, thanks to global support, these ideas became real. With countries like the US, EU, Japan, and more joining in, neuroscience made amazing strides.1
Neuroscientists also found out a lot about our brains. They discovered some gene problems that lead to brain issues.5 They also learned how our brains react to what we see and do. And, as we mentioned, they developed brain-computer systems. These let us interact directly with machines using only our thoughts.5
Cutting-Edge Research Tools
In the 2010s, powerful neuroscience tools became widely used. These tools include optogenetics and single-cell RNA sequencing.1 Optogenetics lets scientists control neurons using light. It means memories can be placed and neural activity studied in animals that move freely. Single-cell RNA sequencing helps study the genetic profiles of single neurons. This knowledge is key to understanding the brain’s cell types.1
Optogenetics and Single-Cell RNA Sequencing
These advanced tools have greatly improved our brain mapping and understanding. They help us follow neural activity and model complex brain processes.1
Brain Organoids and Developmental Neurobiology
Brain organoids, also known as mini-brains, look like those of preterm babies. They’re great for studying how brains develop and Issues like autism and schizophrenia.6 These miniature brains are amazing models of the growing brain. They let scientists examine intricate brain processes and diseases in new ways.1
Live 3D Brain Function Mapping
Scientists found a new way to chart the brain. They combined detailed brain structure maps with direct brain activity mapping in real time.7 This is a first. They used a special kind of microscopy along with a mapping technique. Now, they can see how neurons, blood vessels, and myelin in deep brains are working in live mice.7 This is huge for studying brain reactions and differences between good and sick brain health.7 The method lets researchers watch the brain work in 3D as things happen, helping us figure out how our brains solve problems.
This new 3D brain mapping method is a big breakthrough. It pairs functional brain imaging with detailed structure data. Now, they watch how single neurons, blood vessels, and myelin in live mice’s brains do their job.7 This way lets scientists look at brain responses and spot differences in brain health.7
Mapping brain work as it happens is a key step forward.7 This method, using both structure and function info, is a major jump in brain understanding.7 It could help in many areas, from understanding how our brains react to things, to pointing out health contrasts in the brain.7 It could even explain how our brains handle tricky thinking tasks.
Capturing Decision-Making in Real-Time
At Stanford University, a team has created a technique called COSMOS. This method shows movies of how the brain works in a mouse using a special microscope.1 It captures videos of electrical signals. With these videos, scientists can see the brain in action, looking at how it senses things and makes the body move. This helps them understand how we make decisions.1 COSMOS could be very useful for testing psychiatric drugs and seeing how well they work.1

Sleep’s Role in Artificial Intelligence
Google’s DeepMind AI had a big win by copying the brain’s neo-cortical columns. This let it be super smart but use less computer power.8 It turns out, like us, AI networks need to take breaks. When they do, they work better.8 This discovery shows neuroscience and AI coming together may create very intelligent computers.8
We’re learning how sleep affects AI’s work through studying neural networks.8 The American Academy of Sleep Medicine and other groups see AI as key to better sleep medicine.9 They use AI to find sleep issues and improve treatments, like helping people with sleep apnea.9
