Ultrafast tracking of sound location changes as revealed by human auditory evoked potentials.
The rapid discrimination of auditory location information enables grouping and selectively attending to specific sound sources. The typical indicator of auditory change detection is the mismatch negativity (MMN) occurring at a latency of about 100-250 ms. However, recent studies have revealed the existence of earlier markers of frequency deviance detection in the middle-latency response (MLR). ...
متن کاملMultiple time scales of adaptation in auditory cortex neurons.
Neurons in primary auditory cortex (A1) of cats show strong stimulus-specific adaptation (SSA). In probabilistic settings, in which one stimulus is common and another is rare, responses to common sounds adapt more strongly than responses to rare sounds. This SSA could be a correlate of auditory sensory memory at the level of single A1 neurons. Here we studied adaptation in A1 neurons, using thr...
متن کاملEarly change detection in humans as revealed by auditory brainstem and middle-latency evoked potentials.
The ability to detect unexpected novel stimuli is crucial for survival, as it might urge a prompt adaptive response. Human auditory novelty detection has been associated to the mismatch negativity long-latency auditory-evoked potential, peaking at 100-200 ms. Yet, recent animal studies showing novelty responses at a very short latency (about 20-30 ms) in individual neurons already at the level ...
متن کاملTemporal and spatial aspects of hearing as revealed by auditory evoked potentials
The present study investigates the relationship between evoked responses to transient broadband chirps and responses to the same chirps when embedded in longerduration stimuli. It examines to what extent the responses to the composite stimuli can be explained by a linear superposition of the responses to the single components, as a function of stimulus level. In the first experiment, a single r...
متن کاملAuditory evoked potentials and multiple sclerosis.
UNLABELLED Multiple sclerosis (MS) is an inflammatory, demyelinating disease that can affect several areas of the central nervous system. Damage along the auditory pathway can alter its integrity significantly. Therefore, it is important to investigate the auditory pathway, from the brainstem to the cortex, in individuals with MS. OBJECTIVE The aim of this study was to characterize auditory e...
