Autonomic nervous system, showing splanchnic nerves in middle, and the vagus nerve as "X" in blue. The heart and organs below in list to right are regarded as viscera. The autonomic nervous system has been classically divided into the sympathetic nervous system and parasympathetic nervous system only (i.e., exclusively motor).
There are also criticisms of the two-factor theory that come from a theoretical standpoint. One of these criticisms is that the Schachter-Singer Theory centers primarily on the autonomic nervous system and provides no account of the emotional process within the central nervous system aside from signaling the role of cognitive factors.
Early work done linking emotions to psychophysiology started with research on mapping consistent autonomic nervous system (ANS) responses to discrete emotional states. For example, anger might be constituted by a certain set of physiological responses, such as increased cardiac output and high diastolic blood pressure, which would allow us to ...
Polyvagal theory combines ideas from evolutionary biology and neurology, to claim that autonomic reactions have adapted to the phylogenetic development of neural circuits. [14] It claims that the sympathetic nervous system, and two distinct branches of the parasympathetic nervous system, are phylogenetically ordered and activated for responses ...
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
Poffenroth suggests box breathing, also known as square breathing or 4-4-4 breathing, as a "powerful 'neurohack' that directly influences our autonomic nervous system." The method is simple ...
The nerve tissue that lies outside of the central nervous system is collectively known as the peripheral nervous system. This system can be further divided into the autonomic and somatic nervous system. The autonomic system can be referred to as the involuntary component that regulates bodily organs and mechanisms, such as digestion and ...
Some of these biological measures may be more effective research tools than others. More rapidly fluctuating indices, such as autonomic responses, for example, are proposed to be more temporally sensitive measures of biological co-regulation.
