Additionally, the authors proposed that, based on the findings, methanolic extract of Asparagus racemosus probably attenuates anxiety behaviour through modulation of the amygdalar serotonergic and norepinephrinergic systems.
Different types of norepinephrinergic receptors are involved in preoptic area mediated independent modulation of sleep-wakefulness and body temperature.
Further, researchers have suggested that attentional control involves two separate neural systems: (a) an activation system that is centered in the left hemisphere and specializes in analytic, sequential, and routinized cognitive operations, such as motor responses and is modulated by dopaminergic transmitters, and (b) an arousal system that is centered in the right hemisphere and is responsible for holistic, parallel, and novel cognitive functions, such as perceptual orienting responses and is modulated by norepinephrinergic neurotransmitters (Tucker, 1986; Tucker & Williamson, 1984).
