AP PSYCHOLOGY

Detailed explanation-1: -Flavour results primarily from the combination of three discrete senses: taste, somatosensation and olfaction. In contrast to this scientific description, most people seem unaware that olfaction is involved in flavour perception.

Detailed explanation-2: -When it comes to tasting food, it starts from the tongue where the taste receptor senses the tastant and passes the signal to the insula brain region” taste cortex through the thalamus; meanwhile, the reward system takes the signal from the frontal cortical to get the feel of desire to eat food.

Detailed explanation-3: -Tastes are mainly perceived on the tongue and mediated by the chemosensory gustatory system [2]. Taste sensations start by chemical compounds (tastants) binding to taste-receptor-cells (TRCs) assembled in taste buds located within gustatory papillae.
