The sound of speech elicits similar neural responses and stimulates the same brain regions in humans, guinea pigs, and macaque monkeys.
Neurological symptoms associated with COVID-19, from losing the sense of smell to stroke, are linked to a six-fold higher risk of dying as a result of coronavirus.
Adolescents with a higher risk for developing psychosis have subtle differences in brain structure, including lower cortical thickness than their peers without risk factors. In those who developed psychosis, the cortical thinning was most pronounced in several areas of the temporal and frontal regions of the brain.
The VGLUT protein is more abundant in the dopamine neurons of female fruit flies, rodents, and humans than in males. The finding shed light on why females have greater resilience to age-related dopamine neuron loss and disorders such as Parkinson's disease.
Anti-psychotic drugs do not only block dopamine signaling in the brain, they also block dopamine signaling in the pancreas. Blocking dopamine signaling in the pancreas leads to uncontrolled production of blood-glucose regulating hormones, increasing obesity and diabetes risks.
Study reports a metabolite produced following the consumption of dietary soy may lower risk factors for dementia.
Transcranial vagus nerve stimulation could significantly improve a person's ability to learn the sounds of a new language. The non-invasive stimulation technique could have positive implications for boosting other types of learning also.
Machine learning algorithm allows a brain-computer interface to readjust itself continually in the background to ensure the system is always calibrated and ready to use.
