Neurotransmitters atomic number 18 chemicals that enable impulses within the timbre to be transmitted from one and only(a) atomic number 18a of the reason to an opposite.

However, self-report measurements were used, which are indispensable and so may not be valid. Raleigh et al. (1991) also supports the serotonin has an effect on behaviour. There conducted a require on vervet monkeys, they found that the monkeys fed on data-based diets high in tryptophan, which i! ncreases serotonin levels, exhibited decreased levels of aggression. And monkeys fed on diets that were low in tryptophan exhibited increased aggressive behaviour. This audition has low ecologic validity as it was conducted in a lab under(a) artificial conditions. It is also arguable that as the experiment was conducted on animals it is hard to compare to humans. It was highly...If you want to charter a panoptic essay, order it on our website: OrderEssay.net
