Brain network that controls, redirects attention identified

A unique brain network in humans controls and redirects attention, allowing us to select and prioritize information based on our needs. This network, which includes the dorsal and ventral attention networks, may have evolved to better process complex social cues and distinguish between relevant and irrelevant stimuli.

Evolving a bigger brain with human DNA

Researchers found a key difference in human and chimpanzee DNA that boosts brain size in mouse embryos. This discovery sheds light on the genetic basis of human brain evolution and may help explain why humans have unique capabilities compared to chimps.

Do viruses make us smarter?

Researchers found that endogenous retroviruses, constituting around 5% of human DNA, regulate gene expression and have an important regulatory role in the brain. The study suggests that viruses take a firm hold on cellular machinery over evolution, leading to complex brain functions.

Study cracks how the brain processes emotions

Researchers at Cornell University have discovered that the human brain uses fine-grained patterns of neural activity to represent emotions in a standardized code. This code allows individuals to share similar emotional experiences, regardless of personal perspectives or cultural backgrounds.

Expanding our view of vision

Researchers have noninvasively mapped human brain activity with unique accuracy, identifying both location and timing of brain processes. The study used a novel brain-scanning technique combining fMRI and MEG data to pinpoint when the brain recognizes objects and categorizes them.

Sugar-burning in the adult human brain is associated with continued growth, and remodeling

Research published in Cell Metabolism reveals that hotspots of fuel consumption in the adult brain are associated with ongoing development and remodeling. The study identifies 16 brain regions with elevated levels of aerobic glycolysis, which is linked to gene expression related to growth, synaptic transmission, and neurogenesis.

Where does dizziness come from?

Johns Hopkins researchers pinpointed a site in the right parietal lobe that plays a crucial role in recognizing which way is straight up and down. Disruptions to this process can cause spatial disorientation and dizziness, but the study suggests that trans-cranial magnetic stimulation (TMS) could be used to treat chronic dizziness.

Social status and power of action of speakers determine the way their statements are perceived

A study published in PLOS ONE found that listeners' brain reactions differ depending on the speaker's perceived ability to act upon their words. Researchers used EEG recordings to compare reactions to statements made by influential and non-influential speakers, revealing a significant impact of social status on neural responses.

Brain images of previously unattainable quality

The BigBrain model is based on data from over 7,400 tissue samples and provides a detailed understanding of the normal structure of different functional areas of the brain. The high-resolution model will contribute to precise identification and evaluation of changes in the brains of patients with neurodegenerative diseases.

Human brain treats prosthetic devices as part of the body

Research shows that individuals with spinal cord injuries perceive their wheelchairs as a functional substitute for their affected body part. This perception is not limited by time since injury or experience with using the wheelchair, indicating a deeper integration of prosthetics into bodily awareness.

Pioneering research helps to unravel the brain's vision secrets

A new study identified two neighboring areas of the cortex as processing different types of visual information independently. The researchers used magnetic fields to disrupt neural activity, revealing that one area plays a causal role in processing orientation, while another underpins shape recognition based on curvature differences.
