What is the relationship between nasal dominance and brain hemisphere lateralization?
Best insight from top research papers
Nasal dominance, or the alternating airflow between the right and left nostrils known as the nasal cycle, has been found to be related to brain hemisphere lateralization. Studies have shown that changes in electrocortical activity, as measured by the electroencephalogram (EEG), correlate with changes in nostril dominance . The dominant hemisphere, as indicated by greater integrated EEG values, corresponds to the contralateral nostril with predominant airflow . Additionally, there is evidence of an inverse relationship between the nasal cycle and the alternating dominance of activity in the two cerebral hemispheres . This suggests a common mechanism of regulation between the nasal cycle and cerebral dominance . Furthermore, alterations in neurotransmitter levels, specifically catecholamines, have been observed to parallel the pattern of airflow in the nasal cycle . These findings indicate a connection between nasal dominance and brain hemisphere activity.

Do temporal processes underlie left hemisphere dominance in speech perception?5 answersTemporal processes do play a crucial role in the left hemisphere dominance observed in speech perception. While bilateral activation occurs in response to speech-derived acoustic modulations, left hemisphere dominance is evident specifically in processing intelligible speech, involving superior temporal cortex, inferior frontal cortex, and insula. The left hemisphere specialization for speech is primarily based on linguistic properties rather than specific acoustic features, as seen in PET studies. Additionally, the lateralization patterns observed in ERP experiments support the idea that auditory processing of pitch variations (bottom-up) elicits greater right hemisphere activation, while linguistic processing of lexical tones (top-down) elicits greater left hemisphere activation. This suggests that the left hemisphere dominance in speech perception is indeed influenced by temporal processes.
What is the evidence of lateralization in olfactory processing in the brain?5 answersEvidence from multiple studies suggests lateralization in olfactory processing in the brain. Research indicates that the dominance of one hemisphere, particularly the right hemisphere, is observed in processing social and aversive odors, as well as in analyzing familiarity of olfactory stimuli. EEG studies have shown that right-nostril stimulation is associated with faster microstate transition and longer involvement of specific brain areas, potentially indicating nostril dominance in bimodal odor perception. Furthermore, EEG cross-frequency coupling analysis during exposure to fragrances revealed right-lateralized θ - γ coupling and left-lateralized α - γ coupling, corresponding to memory and emotional processing, respectively, suggesting functional interactions between frontal and temporal brain regions. Coherence analysis of EEG data also demonstrated a lateralization effect in the human brain, with stronger collaborative effects in the left hemisphere during pleasant olfactory stimuli.
What are the differences between the hemispheres of the brain?5 answersThe differences between the hemispheres of the brain are multifaceted. The left hemisphere is often associated with language functions, analytic reasoning, and cognitive tasks such as grammar and vocabulary. On the other hand, the right hemisphere plays a special role in tasks involving spatial attention, face recognition, perception, affect, and affective prosody. Neuroimaging studies have revealed anatomical and cognitive differences between the two hemispheres, including topological organization and functional connectivity patterns. The left hemisphere is considered dominant due to its language abilities and problem-solving skills, while the right hemisphere contributes to emotional and affective disturbances. These differences in hemispheric specialization may explain variations in behaviors, cognition, and cognitive impairments associated with conditions such as depression.
How can nanoparticles be delivered through the nose to the brain?4 answersNanoparticles can be delivered through the nose to the brain using the nose-to-brain drug delivery approach. This approach involves bypassing the blood-brain barrier (BBB) and directly transporting therapeutic molecules to the brain. One method for nose-to-brain drug delivery is the use of solid lipid nanoparticles (SLNs). SLNs are composed of a solid lipid core surrounded by a surfactant coating, which allows for the encapsulation of hydrophilic and hydrophobic drugs. Another approach is the use of nanoparticles as a platform for drug and gene delivery. Nanoparticles offer advantages such as protecting therapeutic drugs from degradation and enabling more precise drug delivery to the brain. Different types of nanoparticles, such as lipid-polymer hybrid (LPH) nanoparticles and starch-based nanoparticles, have been developed for nose-to-brain drug delivery. These nanoparticles can enhance drug loading, improve brain bioavailability, and reduce side effects. Overall, nanoparticles provide a promising strategy for delivering drugs through the nose to the brain.
What tasks require the coordination of both hemisphere in human brain?\?5 answersTasks that require the coordination of both hemispheres in the human brain include learning new postural tasks, instructed-delay reaching tasks, and bimanual coordination tasks. In learning new postural tasks, patients with hemiparesis after stroke were trained to change the position of the center of pressure using both hemispheres. In instructed-delay reaching tasks, bilateral encoding was found in the left hemisphere, indicating similar neural representations for right and left arm movements. In bimanual coordination tasks, patients with left hemisphere damage showed poor interlimb coordination, while those with right hemisphere damage did not show significant differences compared to controls. These findings suggest that both hemispheres are involved in coordinating movements and maintaining balance in various tasks.
Do Spanish rr productions demonstrate a lateralization pattern that is consistent with hemispheric dominance?5 answersSpanish rr productions do not demonstrate a consistent lateralization pattern that is consistent with hemispheric dominance. The study by Shea et al. found different patterns of unique and shared variance across English and Spanish for factors related to dominance and proficiency, suggesting that dominance and proficiency should be considered as separate but related constructs when analyzing heritage speaker linguistic data. Pinel et al. also found partially dissociated patterns of lateralization within the language network, indicating that an overall "dominance" model does not explain the lateralization of language and symbolic operations. Furthermore, Machuca Aceituno and Fernández Cano found no significant correlation between hemispherical laterality and reading-writing performance, refuting the belief that one depends on the other. Therefore, the evidence suggests that the lateralization pattern of Spanish rr productions is not consistent with hemispheric dominance.
