Esperimento:<\/span><\/p>\n

Seventeen healthy adults (20\u201334\u00a0years old) were studied during attention task with blood oxygenation level-dependent functional (fMRI) at 3.0 T MRI. (\u2026) Participants were instructed to press a button with the right or left thumb according to the direction of a centrally presented arrow. Each participant underwent two back-to-back ANT sessions with or without chewing gum, odorless and tasteless to remove any effect other than chewing.<\/em><\/p><\/blockquote>\n

Da un lato, il risultato smentisce la <\/span>tesi<\/strong><\/a> secondo la quale masticare gomma americana inficia la <\/span>coordinazione motoria, in particolare del presidente Ford<\/span>:<\/span><\/p>\n

Behavioral results showed that mean reaction time was significantly decreased during chewing condition, regardless of speed-accuracy trade-off, although there were no significant changes in behavioral effects (both alerting and conflict effects). <\/em><\/span><\/p><\/blockquote>\n

Significant nel senso di circa 496 millisecondi invece di 545. “Dall’altro” sembra la <\/span>conferma la tesi di <\/span>Edward Vul<\/strong><\/a> sulle voodoo correlations nelle neuroscienze, grazie a un audace nesso tra una “performance cognitiva superiore” e una risposta motoria accelerata dallo stato di vigilanza (alertness) rafforzato dall’attivit\u00e0 mascellare:<\/span><\/p>\n

On the other hand, fMRI analysis revealed higher activations in the anterior cingulate cortex and left frontal gyrus for the executive network and motor-related regions for both attentional networks during chewing condition. These results suggested that chewing induced an increase in the arousal level and alertness in addition to an effect on motor control and, as a consequence, these effects could lead to improvements in cognitive performance.<\/em><\/span><\/span><\/p><\/blockquote>\n
