SEROTONIN AND STRESS. "The ability of the gut microbiota to control tryptophan metabolism along the kynurenine pathway...the enzymes of this pathway are immune- and stress-responsive." Tryptophan is the starting point for the synthesis of serotonin. https://lnkd.in/eTgJdPy View in LinkedIn

PIEZO 'PUTER. "New polymer-piezoelectric hybrid creates potential for 'materials that compute'. A hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs." https://lnkd.in/egr-WpF View in LinkedIn

SEROTONIN AT THE TASTE BUD. "A large body of evidence suggests that 5-HT is used as a neurotransmitter in the taste bud to modulate cellular responses to tastant stimulation even before transmission to primary affective gustatory neurons." https://lnkd.in/eaetUhy View in LinkedIn

PIEZO HEARING. "In response to mechanical stimuli, piezoelectric materials generate electricity, suggesting that they could be used in place of hair cells to create an artificial cochlear epithelium." https://lnkd.in/eSZn2RU View in LinkedIn

MECHANISM. "5-HT and NA affect taste cell excitability by altering ion channel function. 5-HT modulates response in primary gustatory neurons."Serotonin and noradrenaline MOA. https://lnkd.in/eaetUhy View in LinkedIn

"PIEZOELECTRIC MATERIALS mimic the function of the cochlear sensory epithelium. Cochlear hair cells convert sound vibration into electrical potential, and loss of these cells diminishes auditory function." https://lnkd.in/eSZn2RU View in LinkedIn

DEPRESSION and anxiety also result in diminished appetite. There is considerable evidence that 5-HT and NA are involved in taste regulation at the level of the taste bud. https://lnkd.in/eaetUhy View in LinkedIn

BUG POWER. "The first of its kind to produce electricity by harnessing the piezoelectric properties of a biological material and could lead to devices that harness electrical energy from the vibrations of everyday tasks. By using viruses that convert mechanical energy into electricity." https://lnkd.in/e966GiP View in LinkedIn

HUMAN TASTE THRESHOLDS are modulated by serotonin (5-HT) and noradrenaline (NA). While normally very stable, and genetically determined, taste thresholds can vary considerably in diseases such as depression and anxiety, and as such are very plastic. https://lnkd.in/eaetUhy View in LinkedIn

BUG POWER. "Scientists at the Berkeley Lab have developed a way to generate power using harmless viruses that convert mechanical energy into electricity." https://lnkd.in/e966GiP View in LinkedIn
