Researchers found that the brain's auditory cortex responds strongly to positive human sounds coming from the left, but not from the right or front. This bias may have an evolutionary advantage, as it could help detect potential threats or predators.
Researchers employed computer vision to extract social behaviors and linked them to brain synchronization patterns in a novel approach. During cooperative play, brain synchronization was strongest when participants shared gaze, while individual play showed increased within-brain synchronization.
Researchers at the HSE Centre for Language and Brain found that a thicker corpus callosum is associated with less lateralization of language functions to the right hemisphere. The study used advanced neuroimaging methods, including fMRI, to measure brain activity while participants completed a sentence completion task.

Researchers discovered that synchronized neural oscillations in the right hemisphere of the brain induce empathic behavior in mice, allowing them to perceive and share each other's fear. The study identified the causal relationship between 5-7 Hz oscillations in the cingulo-amygdala circuit and empathic responses.
A study by HSE researchers found that only the left inferior frontal gyrus is critically involved in action naming, which could help preserve speech in patients after brain surgery. The study used fMRI and rTMS to stimulate the brain and found that stimulating this region led to more accurate action naming.

The study found differences in brain activity patterns between healthy individuals and those with spatial neglect, suggesting a shift in spatial processing to the left hemisphere.
In a groundbreaking study, researchers found that children's brains use both hemispheres to process language, whereas adults typically rely on one hemisphere. This discovery suggests that children's brains are more adaptable and resilient, allowing them to recover from neural injuries more effectively.
Research at Goethe University Frankfurt reveals that both hemispheres of the brain contribute to speech control, with the left hemisphere handling fast processes and the right hemisphere controlling slower processes. This discovery challenges the long-held assumption that the right hemisphere only analyzes spoken words.
A recent study by Drexel University's Creativity Research Lab found that creativity is primarily driven by the right hemisphere in jazz guitarists during improvisation. Inexperienced musicians rely on their right hemisphere, while highly experienced musicians use their left hemisphere for creative tasks.
A study published in Neuroscience and Biobehavioral Reviews found that between 66-72% of people hold infants with their left arm. The preference is similar across men and women, and may be linked to emotional processing in the brain.
Researchers discovered that the right hemisphere plays a crucial role in processing foreign speech sounds at the beginning of language learning. Successful learners showed increased activity in the right hemisphere during sound recognition tasks. The study's findings have the potential to improve instructional methods for adult learners.
Researchers discovered that individuals with epilepsy exhibit increased high-frequency brain activity in the right hemisphere when making risky bets and the left hemisphere when avoiding risks. The findings suggest a brain-based mechanism for risk-taking biases, which can be influenced by past behaviors.
Biopsychologists demonstrate that subtle timing differences in the right hemisphere allow it to control specific functions, while the left hemisphere delays its activity. The study reveals a sophisticated mechanism underlying hemispheric dominance.
A study published in Cell Reports found that a child's brain can reorganize its visual system after losing parts of the visual cortex. The child, UD, had nearly half of his right hemisphere removed due to epilepsy, but his brain compensated by using the intact left hemisphere for tasks like facial recognition and object analysis.
Researchers studied over 2,500 hugs to understand how emotional context affects hug behavior. They found that emotional states influence the lateralization of hugs, with left-sided hugs more common in positive situations and right-sided hugs in negative contexts. Handedness and footedness also play a role in predicting hug direction.
A hyperactive network in the right frontal part of the brain plays a crucial role in stuttering by inhibiting speech movement planning and execution. The more severe the stuttering, the stronger the connections between brain regions involved in neural inhibition of speech movements.
Research at the Max Planck Institute for Human Cognitive and Brain Sciences reveals that hyperactivity in the right hemisphere of the brain is central to stuttering. The study found a stronger connection between brain regions involved in speech movements, leading to impaired fluency.
A study found that dogs use left and right hemispheres to process words and intonation, integrating information to arrive at a unified meaning. Dogs also activate their reward center when they hear praise in praising intonation, suggesting they can combine word and tone for correct interpretation.
A study by Brown University researchers found that one brain hemisphere remains more awake than the other during deep sleep on the first night in a new place. This 'first-night effect' is thought to be an evolutionary adaptation to protect against potential danger.
Researchers found that patients with aphasia who performed better on speech-fluency tests had higher structural integrity in right hemisphere regions. These areas were found to contribute to speech-fluency, suggesting the right side of the brain reorganizes itself for recovery.
Researchers investigate brain structure involved in imitation after stroke or brain injury, discovering the importance of similarity between observed action and produced movement. Lesions in the left hemisphere affect anatomical match, while those in the right hemisphere impact spatial translation.

The study used electroencephalography to track brain activity in response to facial images, revealing a unique right-hemisphere processing of faces.
Researchers found that the right hemisphere of the brain is more integrated and communicative than the left hemisphere during rest, regardless of hand dominance. This study may help explain why power naps benefit focus and mental clarity.
A new study reveals a consistent pattern of brain injury to the frontal lobe and right hemisphere causes delusions. The overcompensation of the left hemisphere leads to the creation of false narratives that cannot be edited, resulting in pathologic beliefs.
Researchers found asymmetrical synaptic structure and molecule composition between left and right hippocampus synapses. This discovery sheds light on the distinct neural mechanisms underlying learning and memory processes.

This underdiagnosis poses challenges for optimizing stroke management, particularly in the early stages.
Researchers at Purdue University found that adults who stutter process language differently than those who don't, even when not speaking. The study, published in August, measured brain electrical activity and response time to find complex interactions between language and motor systems.
Researchers aim to better understand the nuances of language comprehension in individuals with right hemisphere stroke, which often affects word meanings and phrases. The study will use MRI scans to determine if lesion location impacts communication deficits.
