COVID-19 threatens the entire nervous system

Roughly 50% of patients hospitalized for COVID-19 experience neurological symptoms including headaches, dizziness, smell and taste disorders, and stroke, a new study reports. Coronavirus may affect the entire nervous system, including the brain, spinal cord, and muscles. Neurological symptoms of COVID-19 may appear before the fever and cough commonly associated with infection. Read More

Loss of smell and taste validated as COVID-19 symptoms in patients with high recovery rate

Study confirms sensory loss associated with taste and smell is strongly linked to early coronavirus infection. Based on the findings, people who report olfactory or taste loss are ten times more likely to have COVID-19 than other infections. Patients reported their sensory loss to be profound rather than mild. Encouragingly, the rate of sensory recovery was high, with patients reporting a return of normal smell and taste function within two to four weeks, which matches the time of disease recovery. Researchers also found people who reported sore throats more often tested negative for COVID-19. Read More

The science of how diet can change the way sugar tastes

Taste perception appears to be controlled by dopamine in fruit fly models. Tracing the neural pathway, researchers found the same pathways were associated with controlling learning and memory. The network also appears to enhance taste sensations. Researchers also discovered eating lots of sugar suppresses sweet taste perception. Read More

Loss of smell and taste is strongest predictor of early COVID-19 infection

User data from a new COVID-19 symptom tracking app reveals a loss of taste and smell are the strongest predictors of a positive coronavirus diagnosis. Using the data, researchers have developed a model to identify which combination of symptoms together could best predict COVID-19 infection in individuals. Read More

Posture impacts how you perceive your food

Whether you stand up to eat or sit for dinner, your posture influences how much you enjoy your meal. Standing to eat mutes taste perception and reduces sensory sensitivity, resulting in a decreased enjoyment of food. Read More

Neurons that encode sweetness identified: Mouse study

SatB2PBN-expressing neurons in the parabrachial nucleus play a key role in processing and encoding sweet tastes. The SatB2PBN neurons relay sweet taste signals from the gustatory thalamus to the cortex in mouse models. Read More
