"The sensory nervous system is a part of the nervous system responsible for processing sensory information."
Sensory coding refers to the process by which the nervous system represents and processes sensory information from the environment. It involves the conversion of sensory input into a neural code that can be interpreted by the brain.
Transduction: The process of converting physical stimuli into neural signals that can be processed by the brain.
Receptor Cells: Cells that are specialized to respond to specific stimuli, such as light or sound, and to initiate the process of transduction.
Sensory Adaptation: The process by which the sensitivity to a particular stimulus decreases over time.
Sensory Thresholds: The minimum amount of stimulation required to detect a particular stimulus, such as a sound or a touch.
Sensory Modalities: The five senses (vision, hearing, touch, taste, and smell) through which humans and animals receive information about the environment.
Sensory Attention: The ability to focus on specific sensory input while filtering out other distractions.
Sensory Integration: The process by which the brain combines sensory information from multiple sources to create a unified perception of the world.
Sensory Maps: The organization of sensory information in the brain in a spatially arranged pattern.
Sensory Pathways: The neural routes that transmit sensory information from the receptors to the brain.
Perception: The process by which the brain interprets sensory information and gives it meaning.
Spatial Coding: The method of encoding a stimulus's location in space by the location of sensory receptors that are activated.
Temporal Coding: The method of encoding information about the timing of a stimulus by the pattern of activity generated by sensory neurons over time.
Intensity Coding: The method of encoding information about the strength of a stimulus with the amount of activity generated by sensory receptors.
Frequency Coding: The method of encoding information about a stimulus's frequency by the frequency of the neural activity in sensory receptors.
Population Coding: The method of coding by which a stimulus is encoded by patterns of activity across a population of neurons that work together in a coordinated way.
Feature Coding: The method of coding that involves encoding specific features of a stimulus, such as its shape, color or texture.
Gate-Control Theory: The method by which pain signals are selectively blocked or transmitted to the brain, and this theory proposes that certain neural "gates" in the spinal cord can be opened or closed to regulate pain sensation.
Contrast Coding: The method of coding used to distinguish between different levels of luminance or color by codifying the differences in intensity and color.
Adaptation Coding: The method of coding that occurs when our sensory receptors become accustomed to persistent or repetitive stimuli, reducing our sensitivity.
Topography Coding: The method of coding that refers to the layout of sensory regions in the brain, which maps the sensory surface of our body or surroundings.
"A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception."
"Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, balance, and visceral sensation."
"Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them."
"The receptive field is the area of the body or environment to which a receptor organ and receptor cells respond."
"For instance, the part of the world an eye can see is its receptive field; the light that each rod or cone can see is its receptive field."
"Receptive fields have been identified for the visual system, auditory system, and somatosensory system."
