Splet07. jan. 2024 · The mammalian taste system is a prominent example of a major sensory system hardwired to trigger predetermined actions and behaviors, such as our innate attraction and consumption of sweet compounds and aversion to bitters ( Scott, 2005 ; Yarmolinsky et al., 2009 ). The Triune Brain is divided into three sections: Reptilian, Paleomammalian and Neomammalian. MacLean proposed that the human skull doesn't just contain one single brain, according to his Triune Brain Theory, it in fact holds three.
