Equilibrioception

Propriocezione.

The general sensation and perception of touch

which is known as somatosensation, can be separated into

• light pressure, deep pressure, vibration, itch, pain, temperature, or hair movement.

The general sensation and perception of taste

can be separated into submodalities of

• sweet, salty, sour, bitter, spicy, and umami,

all of which are based on different chemicals binding to sensory neurons.

Merkel cells, type I cutaneous mechanoreceptors wp

1. Low frequency vibrations
2. located in the stratum basale of the epidermis.

lamellated (Pacinian) corpuscles wp

1. deep pressure and vibration
2. located deep in the dermis, or subcutaneous tissue.
3. encapsulated endings

tactile (Meissner) corpuscles. wp

1. Light touch
2.  
3. encapsulated endings

stretch receptors, or bulbous corpuscles, or Ruffini corpuscles, or type II cutaneous mechanoreceptors. wp

stretching of the skin

hair follicle plexus

1. detect the movement of hair at the surface of the skin, such as when an insect may be walking along the skin.
2. a plexus of nerve endings that wrap follicles

Interoception

1. Interoception#Interoception_and_emotion
   1. The_Expression_of_the_Emotions_in_Man_and_Animals - Darwin
   2. James-Lange_theory bodily sensations provide the critical basis for emotional experience
   3. The Somatic_marker_hypothesis somatic marker hypothesis expands upon the James-Lange theory and posits that decisions and the ensuing behaviors are optimally guided by physiological patterns of interoceptive and emotional information.
   4. Ensuing models focusing on the neurobiology of feelings states emphasized that the brain's mapping of different physiological body states are the critical ingredients for emotional experience and consciousness.
   5. In another model, Bud Craig argues that the intertwining of interoceptive and homeostatic processes is responsible for initiating and maintaining motivational states and engendering human self-awareness.

internal chemoreception- and osmoreception-based sensory systems lead to various perceptions, such as hunger, thirst, suffocation, and nausea, or different involuntary behaviors, such as vomiting.
