Proteins can also act as brain messengers

Proteins can also act as brain messengers

Brain cells communicate through neurotransmitters like glutamate or dopamine, the substances we got used to reading about when learning about brain function. However, it seems this is not the only way neurons can communicate. A new study suggests that certain proteins can act as brain messengers in the brain. Previously, only pathological proteins like tau […]

Since humans are not very good at predicting the future, even if the help of a magic ball, scientists have developed a new system based on artificial intelligence to help us predict the future risk of suffering from Alzheimer’s disease by analysing certain parameters in brain scans. The research, recently published in the journal Diagnostics […]

The brain plays an essential role in how people navigate the world by generating both thought and behavior. Despite being one of the most vital organs of life, it takes up only 2% of human body volume. How can something so small perform such complex tasks? Luckily, modern tools like brain mapping have allowed neuroscientists […]

NeurobiologyNeuroscience

At a synapse, the plasma membrane of the neuron transmitting the information (the presynaptic neuron) is in close proximity to the membrane of the target cell (postsynaptic) and the two are separated by a space known as the synaptic cleft. Both the presynaptic and postsynaptic sites contain extensive assemblies of molecular machinery that link the […]

One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anaesthesiologist Stuart Hameroff to propose an ambitious answer. They claimed that the brain’s neuronal system forms […]
