Perception

(noun)

The organization, identification, and interpretation of sensory information in order to construct a mental representation through the process of transduction, during which sensors in the body transform signals from the environment into encoded neural signals.

Examples of Perception in the following topics:

  • Sensation to Perception

    • Sensation and perception are two distinct stages of processing during human sensing.
    • Transduction can be likened to a bridge connecting sensation to perception.
    • The resulting mental recreation of the distal stimulus is the percept.
    • Perception is particularly important to our ability to understand speech.
    • These are two optical illusions that illustrate how perception may differ from reality.

  • Sensory Modalities

    • Taste perception is created by combining multiple sensory inputs.
    • Different modalities help determine the perception of taste.
    • Multimodal perception comes into effect when a unimodal stimulus fails to produce a response.
    • Proprioception and touch are related in subtle ways, and their impairment results in deep and surprising deficits in perception and action.
    • This is a diagram of how multimodal perception is created by the overlapping and combining of different inputs from the sensory systems.

  • Optic (II) Nerve

    • The optic nerve transmits all visual information including brightness perception, color perception, and contrast.

  • Overview of Sensation

    • Hearing or audition (audioception) is the sense of sound perception.
    • The sense of taste is often confused with the concept of flavor, which is a combination of taste and smell perception.
    • Touch or somatosensation (tactioception, tactition, or mechanoreception), is a perception resulting from the activation of neural receptors in the skin, including hair follicles, tongue, throat, and mucosa.
    • According to psychologists and neuroscientists, however, human brains have a system governing the perception of time.

  • Somatic Sensory Pathways to the Cerebellum

    • A sensory system consists of sensory receptors, neural pathways, and the parts of the brain involved in sensory perception.
    • In short, senses are transducers from the physical world to the realm of the mind where we interpret the information, creating our perception of the world around us.

  • Proprioceptive Sensations

    • It is distinguished from exteroception, perception of the outside world, and interoception, perception of pain, hunger, and the movement of internal organs, etc.

  • Organization of the Nervous System

    • The connections of these neurons form neural circuits that are responsible for our perceptions of the world and determine our behavior.

  • Phantom Limb Sensation

    • Ramachandran and colleagues illustrated this theory by showing that stroking different parts of the face led to perceptions of being touched on different parts of the missing limb.
    • Ramachandran argued that the perception of being touched on different parts of the phantom limb was the perceptual correlate of cortical reorganization in the brain.

  • Cerebral Lobes

    • The temporal lobe is involved in primary auditory perception such as hearing and holds the primary auditory cortex.
    • Anterior parts of this ventral stream for visual processing are involved in object perception and recognition.

  • The Anterior Pituitary

    • Beta-endorphin is a polypeptide that effects the opioid receptor, whose effects include the inhibition of the perception of pain.
