A new Caltech study finds that the brain's anterior cingulate cortex and striatum are involved in decision-making when faced with too many options, leading to a 'choice overload' effect. The ideal number of options is estimated to be between 8 and 15, depending on perceived reward and individual characteristics.
Researchers found that sleep-deprived individuals feel lonelier and less socially attractive, triggering a viral contagion of social isolation. Brain scans showed powerful social repulsion activity in neural networks activated when humans perceive personal space invasion.
