What is the volley principle quizlet?

What is the volley principle quizlet?

volley principle. The Volley Principle is an information encoding scheme used in human hearing. Nerve cells transmit information by generating brief electrical pulses called action potentials. Sound is encoded by producing an action potential for each cycle of the vibration, eg.

What is the volley theory of hearing?

the principle that individual fibers in an auditory nerve respond to one or another stimulus in a rapid succession of rhythmic sound stimuli, whereas other fibers in the nerve respond to the second, third, or nth stimulus.

What is an example of the volley principle?

It has been seen that when being played a pure tone, auditory nerve fibers will fire at the same frequency as the tone. Volley theory suggests that groups of auditory neurons use phase-locking to represent subharmonic frequencies of one harmonic sound. This has been shown in guinea pig and cat models.

What is the place theory of hearing quizlet?

place theory. ability to detect high pitch/ high frequency sound waves, registered within specific places of the cochlea. frequency theory. ability to detect low pitch/frequency sound waves registered by the rate of frequency of neural impulses and transmitted through the auditory nerve.

What are the 4 distinct skin senses that make up touch?

The thousands of nerve endings in the skin respond to four basic sensations — pressure, hot, cold, and pain — but only the sensation of pressure has its own specialized receptors. Other sensations are created by a combination of the other four.

What is the gate control theory quizlet?

Gate-control theory. The theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain. The “gate” is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in larger fibers or by information coming from the brain.

Is the frequency theory correct?

The studies done in the late 20th century have proven the Frequency Theory incorrrect in its assumption of the firing rate of the auditory nerve. Today, it is widely accepted that individual nerve fibers, including that of the auditory nerve, can only fire at a range of 300 to 500 times per second.

Which part of the brain controls smell and taste?

Temporal lobe You have two temporal lobes, one behind each ear. They receive messages from the ears so that you can recognise sound and messages. This part of the brain also recognises speech and is how you understand what someone says to you. It also helps your sense of smell.

What does gate control theory explain?

Briefly, the gate control theory proposes that a mechanism in the dorsal horn of the spinal cord acts as a ‘gate’ that can inhibit or facilitate transmission of nerve impulses from the periphery to the brain.

How do you use gate control theory?

How Gate Control Theory Works. Following an injury, pain signals are transmitted to the spinal cord, then up to the brain. Melzack and Wall suggest that along the way, pain messages encounter nerve gates that control whether these signals are allowed to pass through.

Who developed the concept of central place theory quizlet?

Theory proposed by Walter Christaller in 1933 that explains how and where central places in the urban hierarchy should be functionally and spatially distributed with respect to one another. The area surrounding a central place, from which people are attracted to use the place’s goods and services.
