Blood capillary distribution correlates with hemodynamic-based functional imaging in cerebral cortex.
Our study concerns the mechanisms that underlie functional imaging of sensory areas of cortex using hemodynamic-based methods such as optical imaging of intrinsic signals, functional magneticExpand

Is there a critical period for cochlear implantation in congenitally deaf children? Analyses of hearing and speech perception performance after implantation.
A range of basic and applied studies have demonstrated that during the development of the auditory system, early experimental manipulations or clinical interventions are generally more effective thanExpand

Three Distinct Auditory Areas of Cortex (AI, AII, and AAF) Defined by Optical Imaging of Intrinsic Signals
Using pure-tone sound stimulation, three separate auditory areas are revealed by optical imaging of intrinsic signals in the temporal cortex of the chinchilla (Chinchilla laniger). These areasExpand

Optical Imaging of Intrinsic Signals in Chinchilla Auditory Cortex
We have assessed sound frequency and intensity responses in primary auditory cortex of the (ketamine) anesthetized chinchilla using optical imaging of intrinsic signals. Temporal cortex was exposedExpand

The effects of anesthesia on otoacoustic emissions
We have measured transient-evoked and distortion-product otoacoustic emissions (OAEs) in the chinchilla and compared them in the awake and anesthetized animal (using either ketamine or barbiturateExpand

Basal Cochlear Lesions Result in Increased Amplitude of Otoacoustic Emissions
We have measured the changes in transient otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) during and after ototoxic amikacin treatment in an animal (chinchilla)Expand

Plasticity of tonotopic maps in auditory midbrain following partial cochlear damage in the developing chinchilla
Abstract There is substantial reorganization of the midbrain (inferior colliculus) tonotopic map following neonatally induced partial cochlear lesions in the chinchilla. The most obvious feature ofExpand

Dynamics of real time DPOAE contralateral suppression in chinchillas and humans Dinámica de la supresión contralateral de las DPOAE en tiempo real en chinchillas y humanos
The dynamics of contralateral acoustic suppression were studied using real time (millisecond resolution) distortion product otoacoustic emissions (DPOAEs) in chinchillas and humans. Latency of DPOAEExpand

Tonotopic Mapping in Auditory Cortex of the Adult Chinchilla with Amikacin-Induced cochlear Lesions: Mapeo tonotópico de la corteza auditiva de la chinchilla adulta con lesiones cocleares inducidas
We have found a reorganization of tonotopic maps (based on neuron response thresholds) in primary auditory cortex of the adult chinchilla after amikacin-induced basal cochlear lesions. We find anExpand
