What does phase locking in the auditory nerve help code?
Phase locking has been shown to be the behaviorally relevant temporal code. This study examined the quality and intensity dependence of phase locking in single auditory nerve fibers of the barn owl to define the input to the known brainstem circuit for temporal processing.
What is the point of phase locking?
Phase Locking is an empirical observation that supports the volley principle. When auditory nerve neurons fire action potentials, they tend to respond at times corresponding to a peak in the sound pressure waveform, i.e., when the basilar membrane moves up.
What frequency does phase locking occur?
Phase locking is used in binaural processing for frequencies up to ∼1500 Hz. Estimates of the general upper limit (inc. monaural processing) vary from 1500 to 10000 Hz.
What does phase locked mean EEG?
Conventionally, the definition for evoked response is that it is time-locked and phase-locked to the onset of the stimulation across the trials. To be phase-locked, the EEG signal needs to have the same phase angle at the onset of each trial. An EEG response would have to be strongly time-locked to be phase-locked.
What is phase locking auditory?
Phase locking refers to the tendency of a neuron to fire action potentials at particular phases of an ongoing periodic sound waveform, such as the sinusoidal waveforms that are typically used in physiological studies of the auditory system.
What is phase locking in the auditory system?
In the auditory system, phase locking refers to the fact that the probability of neuronal action potentials (spikes) varies as a function of the phase of low-frequency tones, low-frequency components of broadband sounds, or low-frequency fluctuations of the envelope (for review, see Joris et al., 2004; Heil and …
Why is phase locking important for hearing?
SIGNIFICANCE STATEMENT Phase locking of auditory-nerve-fiber responses to the temporal fine structure of acoustic stimuli is important for many aspects of hearing. In addition to attenuating the AC component, the filter approximately recovers the sinusoidal waveform of the stimulus.
What is two phase locking protocol in DBMS?
Two Phase Locking Protocol also known as 2PL protocol is a method of concurrency control in DBMS that ensures serializability by applying a lock to the transaction data which blocks other transactions to access the same data simultaneously. Two Phase Locking protocol helps to eliminate the concurrency problem in DBMS.
Where does phase locking occur?
the tendency for a neural action potential to occur at a certain phase of a pure-tone stimulus. Typically, an action potential will not occur on every cycle, but when it is generated, it tends to occur at the same point or phase in the stimulus.
What is two-phase locking explain with example?
What is 2 phase locking describe with the help of an example?
Two-Phase Locking (2PL) is a concurrency control method which divides the execution phase of a transaction into three parts. It ensures conflict serializable schedules. If read and write operations introduce the first unlock operation in the transaction, then it is said to be Two-Phase Locking Protocol.
