Question

what is an afterimage? tell me about the gate - control theory of pain. in addition to your usual five senses, there are two other \senses.\ this sense monitors balance in response to movement detected by the proprioceptors. it is your sense of equilibrium or body orientation. this is the _____________. the sense that monitors and coordinates movement and position among body parts through information sent from sensory neurons called proprioceptors is called_________________. if you become deaf, it will most likely be one of these two reasons. this deafness occurs when there is damage to the hair cells located in the inner ear or damage to the auditory nerve. it can be caused by aging, disease, heredity, or exposure to loud sounds and is almost always permanent. you will need a cochlea implant for _________. this deafness occurs when the eardrum is punctured or there is damage to any of the three tiny bones. __________deafness. compare and contrast top - down processing and bottom - up processing. what does interposition tell you about the distance of objects?

Explanation:

1. An after - image is a visual illusion where an image continues to appear in one's vision after the original stimulus is removed. It can be positive (same color as the original) or negative (opposite color).
2. The Gate - control theory of pain suggests that there are "gates" in the spinal cord that can either block or allow pain signals to reach the brain. Non - painful stimuli can close these gates, reducing the perception of pain.
3. The sense that monitors balance in response to movement detected by proprioceptors is the vestibular sense. The sense that monitors and coordinates movement and position among body parts through information from proprioceptors is proprioception.
4. Deafness due to damage to hair cells in the inner ear or the auditory nerve is sensorineural deafness. Deafness due to a punctured eardrum or damage to the three tiny bones is conductive deafness.
5. Top - down processing uses prior knowledge, expectations, and context to interpret sensory information. Bottom - up processing builds perceptions from the raw sensory data, starting with individual features and combining them.
6. Interposition is a monocular depth cue. When one object partially blocks another, the blocked object is perceived as farther away.

Answer:

1. A visual illusion where an image persists after the original stimulus is removed.
2. Theory suggesting spinal cord "gates" can block or allow pain signals.
3. Vestibular sense; Proprioception
4. Sensorineural; Conductive
5. Top - down uses prior knowledge, bottom - up builds from raw data.
6. When one object blocks another, the blocked one is farther away.
