"The Multilingual Mind: Insights from Polyglot Studies"

A study involving polyglots, who are proficient in multiple languages, used functional magnetic resonance imaging to monitor their brain activity while listening to passages in various languages. The study found that the brain's language-processing network showed increased activity when polyglots heard languages in which they were most proficient. However, an exception was observed where some polyglots exhibited a lesser brain response when listening to their native language compared to other languages they knew well. This suggests that polyglots become more efficient in processing their native language, leading to a reduced brain response. The findings provide insight into how the brain processes language and the efficiency of neural processes in language comprehension.

"The Myth of Only Using 10% of Our Brains: Debunked"

The belief that humans only use 10% of their brains is a myth. Neuroscientists confirm that we are always using all of our brain, even at a baseline level. Brain activity is similar to the heart, which keeps pumping even when not working at full capacity. The brain operates through various networks, and no single region acts in isolation. Functional magnetic resonance imaging (fMRI) is the best tool to measure brain activity, showing increased energy use in different regions. As we practice a skill, our brains physically change and become more efficient, requiring less energy. Mental energy is another way to measure brain use, but it is subjective. Ultimately, the notion of using only 10% of the brain is not only incorrect but irrelevant, as the brain can rewire itself and work at its fullest capacity even with a portion injured or removed.

Spiral Brain Waves and Cognitive Function: A Correlation

Researchers have discovered swirling spiral patterns of brain signals on the human cortex that play a crucial role in organizing brain activity and cognitive processing. These spirals facilitate intricate interactions for computational efficiency and allow for flexible reconfiguration of brain activity during various tasks involving natural language processing and working memory. The study's findings were obtained from functional magnetic resonance imaging (fMRI) brain scans of 100 young adults, which the researchers analyzed using methods typically employed to understand complex wave patterns in turbulence.

Targeting the Amygdala: Emotion-Focused Therapy for Bipolar Disorder.

Emotion-focused therapy (FEST) may be effective in the long-term treatment and relapse prevention of bipolar disorder (BD). A new study identifies a therapeutic tool focused on emotional awareness that increased activation and connectivity of an emotion-regulating center in the brain. The study investigated the impact of two psychotherapeutic interventions on BD symptoms and on amygdala activation and connectivity with other emotion-related brain regions using functional magnetic resonance imaging (fMRI). The amygdala helps regulate emotion and detect salient stimuli. In contrast, the patients of the cognitive-behavioral intervention demonstrated increased activation of brain regions related to social function but not altered amygdala activity.
