Regularity of firing of neurons in the inferior colliculus.
The spike discharge regularity of 254 tonically firing units in the inferior colliculus (IC) of the anesthetized guinea pig was studied in response to tones presented at best frequency (BF) to the ear contralateral to the recorded IC. Regularity of firing was measured by calculating the coefficient of variation (CV) as a function of time over the course of a unit's response. Two hundred and fif...
متن کاملSpectrotemporal sound preferences of neighboring inferior colliculus neurons: implications for local circuitry and processing
How do local circuits in the inferior colliculus (IC) process and transform spectral and temporal sound information? Using a four-tetrode array we examined the functional properties of the IC and metrics of its micro circuitry by recording neural activity from neighboring single neurons in the cat. Spectral and temporal response preferences were compared for neurons found on the same and adjace...
متن کاملInfluence of the paraflocculus on normal and abnormal spontaneous firing rates in the inferior colliculus.
Spontaneous firing rates of neurons in the central auditory pathway, such as in the inferior colliculus, are known to be increased after cochlear trauma. This so-called hyperactivity is thought to be involved in the generation of tinnitus, a phantom auditory perception. Recent research in an animal model suggests behavioural signs of tinnitus can be significantly reduced by silencing or removal...
متن کاملTemporal masking reveals properties of sound-evoked inhibition in duration-tuned neurons of the inferior colliculus.
The inferior colliculus (IC) is the first place in the central auditory pathway where duration-selective neurons are found. Previous neuropharmacological and electrophysiological studies have shown that they are created there and have led to a conceptual model in which excitatory and inhibitory inputs are offset in time so that the cell fires only when sound duration is such that onset- and off...
