ABSTRACT The vagus nerve is crucial in regulating physiological functions, including the cardiovascular system. While heart rate (HR) and its variability (HRV) may provide non‐invasive proxies of cardiac vagal activity, transcutaneous auricular stimulation (taVNS) has yielded mixed effects, with limited research on right branch stimulation. In a randomized crossover study 36 healthy participants, we investigated taVNS effects HR HRV indexed by SDRR, RMSSD, HF‐HRV, LF/HF ratio. To assess...
Hunger is commonly linked to negative mood and shifts are thought arise from sensing the body's internal state. However, it unclear whether circulating glucose levels affect subconsciously or via subjectively sensed metabolic states. Here, we continuously monitored interstitial of 90 healthy adults for four weeks while they completed ecological momentary assessments (EMA; M=47 runs per participant) rate their As expected, hungry participants reported lower mood, state ratings were associated...
Humans and other animals constantly evaluate their decisions in order to learn behave adaptively. Experimentally, such evaluation processes are accessed using metacognitive reports made after decisions, typically verbally formulated confidence scales. When subjects report high confidence, it reflects a certainty of being correct, but low might signify either about the outcome, or incorrect. Hence, reflect not only different levels decision certainty, also two directions (certainty correct...
Abstract The dorsal pulvinar has been implicated in visuospatial attentional and perceptual confidence processing. Pulvinar lesions humans monkeys lead to spatial neglect symptoms, including an overt saccade bias during free choices. However, it remains unclear whether disrupting the target selection that relies on a decision leads impairment or more general orienting choice deficit. To address this question, we reversibly inactivated unilateral by injecting GABA-A agonist THIP while two...
Abstract The vagus nerve plays a critical role in balancing the body’s physiological functions, including cardiovascular system. Measures of heart rate (HR) and its variability (HRV) may provide non-invasive proxies vagal activity humans, but transcutaneous auricular stimulation (taVNS) has produced mixed effects so far—limited by lack studies stimulating right branch. Here, we used randomized cross-over design to study taVNS on HR HRV. To estimate how side (left vs. ear) affects function,...
