Summary Introduction
Introduction:
The system in the body that is responsible for making the organism hear is termed as the auditory system. This system is further divided into the peripheral auditory system and the central auditory system. The peripheral auditory system is composed of outer ear, inner ear, and middle ear. The central auditory system is the region from the cochlear nucleus to the primary auditory cortex.

A study testing sensory deprivation took place at McGill University in the 1950’s. What is sensory deprivation?
A desire to persevere with work and to avoid distraction in order to reach personal goals. A state in which there is little or no sensory stimulation. Desires for increased stimulation. Somebody who regularly seeks out thrilling activities such as riding mountain bikes, roller coasters, or even skydiving.
Environmental input to different sensory systems affects different neuroanatomical pathways.
However, there is a basic, common pathway plan that most sensory systems share. Choose the
response option that best describes that plan.
receptors --> hindbrain --> midbrain --> cortical association area
receptors --> medulla --> hypothalamus --> frontal cortex
receptors -> spinal nerves --> midbrain --> temporal cortex
receptors >brainstem --> thalamus --> primary cortical area
An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.
How do we sense different types of pain (very painful vs. not painful at all)? Using the threshold potential and the all-or-none principle, explain how it is possible to sense different levels of pain.

- In the process of sensory coding Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger. The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination. Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity. A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forwardCutaneous receptors are located in the proprioceptors are located in the and cerebral cortex equilibrium These receptors provide sensory input to the primary sensory area of where the information is processed. the muscle spindle pain Cutaneous receptors are made up of numerous sensory receptors, including those for temperature, pressure, touch, and muscles and joints connective tissue One example is a cutaneous receptor that is onion-shaped and detects pressure, called a Pacinian corpuscle sight Proprioceptors help the body maintain and posture. skin of sensory nerve endings wraps around muscle sheath.
