Low-cost blood pressure drug improves brain function in individuals with autism

Neuroscience News
Propranolol, a common 'beta-blocker' drug used to control blood pressure, could be a promising new treatment for those on the autism spectrum. The medication improved cognitive performance and positively altered the frontal-parietal control network, an area of the brain associated with word and information processing, in those with ASD....

Genes associated with left-handedness linked with shape of the brain’s language regions

Neuroscience News
Four genetic regions have been identified as playing a role in left-handedness. Three of the four genes were associated with proteins involved in brain development and structure. Neuroimaging revealed those who were left-handed had increased functional connectivity between left and right language networks. Researchers also found correlations between the genetic regions associated with left-handedness and slightly reduced Parkinson's risk, but a slightly increased risk for schizophrenia.... Read More...

Human perception of colors does not rely entirely on language

Neuroscience News
Based on the study of a stroke patient with damage to the occipito-temporal brain region, researchers made a big discovery about color categorization. They reveal color categorization and naming can be independent in the human brain. The finding challenges long-standing theories of the mandatory involvement of language in adult human cognition and color discrimination.... Read More...

This shows the location of the brain networks

Map of broken brain networks shows why people lose speech in language-based dementia

Neuroscience News
Researchers have identified the location of dysfunctional brain networks that lead to impaired sentence production and word-finding in primary progressive aphasia (PPA). PPA can occur in those with neurodegenerative diseases, such as frontotemporal dementia and Alzheimer's disease. Mapping the networks allows clinicians to apply non-invasive brain stimulation to potentially improve speech in those with PPA. ... Read More...
