Q & A

What is the main focus of the exhibition in Bordeaux?

The main focus of the exhibition in Bordeaux is to explore the intricacies of the human mind and brain, showcasing projects by European researchers aimed at understanding the mysterious parts of the brain and its surprising capabilities.

How has the study of the brain evolved over time?

In the past, the brain could only be studied post-mortem, during or after an autopsy. Today, thanks to imaging diagnostics, we can observe the brain in real-time in living people, which has improved our understanding of its functioning.

What is the significance of the unedited text at a talent show in Lithuania?

The unedited text at a talent show in Lithuania refers to an innovative, unpublished test where patients with cranial trauma wear special plastic glasses that measure brain tissue pressure, a technique that has traditionally only been performed by perforating the skull.

How does the brain's plasticity manifest in the human population?

The brain's plasticity is demonstrated by its ability to adapt and change based on use, experiences, and accumulated knowledge. For example, London taxi drivers have been found to have a more developed hippocampus due to the complex mental maps they must maintain of the city's streets.

What are the objectives of the scientists studying the brain in Vienna?

The scientists in Vienna are investigating the molecular secrets of brain aging, seeking to understand why some brains remain healthy despite age while others develop neurodegenerative diseases like Alzheimer's.

What role do neurons play in the brain's plasticity?

Neurons play the most important role in brain plasticity. They can organize themselves, form connections, and create more synapses based on the stimuli they receive. If they receive fewer stimuli, these connections may diminish or disappear entirely.

How does the Brain-Computer Interface (BCI) work?

The Brain-Computer Interface works by placing electrodes on specific points on the skull where brainwave patterns can be measured. A computer reads the brain activity and translates it into commands that can control external devices, such as computers or prosthetic limbs.

What are some potential applications of BCI technology?

Potential applications of BCI technology include helping paraplegic individuals control devices, interact with video games, operate electronic devices, and even control a wheelchair in a stable and precise manner.

What is the significance of understanding the genetic factors in Alzheimer's disease?

Understanding the genetic factors in Alzheimer's disease is crucial for improving diagnostic capabilities and developing therapies. It may also reveal protective genetic alterations that could help in preventing the disease or slowing its progression.

What future advancements are anticipated for BCI technology?

Future advancements for BCI technology may include more sophisticated devices for remote control, such as flying devices, and practical applications like controlling a computer to improve speed or helping individuals with severe paralysis grasp objects again.

What does the ongoing research on the human brain aim to uncover?

The ongoing research aims to uncover the limits of the human brain, which is a complex and extraordinary organ with many secrets yet to be deciphered. The research is expected to bring about significant advancements in understanding and treating neurological conditions.
