1. Changes in late-latency auditory evoked potentials after tinnitus suppression using auditory stimulation
Abstract Objective: Tinnitus can result from auditory system reorganization due to neural activity dysfunctions. Auditory stimulation can cause temporary or persistent tinnitus alleviation by altering the neural generators. The present study investigated the changes in Late-Latency Auditory Evoked Potentials (LLAEPs) after tinnitus suppression using auditor

2. Staging and neuroprogression in bipolar disorder: a systematic review of the literature
INTRODUCTION: The use of clinical staging models is emerging as a novel and useful paradigm for diagnosing severe mental disorders. The term "neuroprogression" has been used to define the pathological reorganization of the central nervous system along the course of severe mental disorders. In bipolar disorder (BD), neural substrate reactivity is changed by r

3. Análise dos eventos tônicos e fásicos do sono dessincronizado em ratos Wistar com lesão medular contusa / Análise dos eventos tônicos e fásicos do sono dessincronizado em ratos Wistar com lesão medular contusa
After a spinal cord injury (SCI), structural reorganization occurs locally and at multiple levels of the central nervous system (CNS). Compromising of sensory motor functions and significant alterations of other neural functions are normally related after a SCI. The circardians rhythms, specially the sleep-wake cycle are frequently affected after a trauma or

4. Síntese,modelagem e simulação de estruturas neurais morfologicamente realísticas. / Synthesis, Modeling and Simulation of morphologically realistic neural simulation.
Os aspectos morfológicos dos neurônios e estruturas neurais, embora potencialmente importantes, têm recebido relativamente pouca atenção na literatura em neurociência. Este trabalho consiste numa substancial parte de um projeto em desenvolvimento no Grupo de Pesquisa em Visão Cibernética voltado para o estudo da relação formal/função neural. Mais

5. Reorganization of the auditory cortex specialized for echo-delay processing in the mustached bat
Focal excess sensory stimulation evokes reorganization of a sensory system. It is usually an expansion of the neural representation of that stimulus resulting from the shifts of the tuning curves (receptive fields) of neurons toward those of the stimulated neurons. The auditory cortex of the mustached bat has an area that is highly specialized for the proces

6. Axon substitution in the reorganization of developing neural connections.
Insights into the mechanisms of normal and pathological neural development may be gained by studying the reorganization of developing neural connections, caused experimentally or by disease. Many reorganized connections are assumed to arise by the anomalous stabilization of transient connections that occur during normal development. We report that, although

7. The corticofugal system for hearing: Recent progress
Peripheral auditory neurons are tuned to single frequencies of sound. In the central auditory system, excitatory (or facilitatory) and inhibitory neural interactions take place at multiple levels and produce neurons with sharp level-tolerant frequency-tuning curves, neurons tuned to parameters other than frequency, cochleotopic (frequency) maps, which a

8. Transient “deafness” accompanies auditory development during metamorphosis from tadpole to frog
During metamorphosis, ranid frogs shift from a purely aquatic to a partly terrestrial lifestyle. The central auditory system undergoes functional and neuroanatomical reorganization in parallel with the development of new sound conduction pathways adapted for the detection of airborne sounds. Neural responses to sounds can be recorded from the auditory midbra

9. Direct interaction of NRSF with TBP: chromatin reorganization and core promoter repression for neuron-specific gene transcription
Neural restrictive silencer factor, NRSF (also known as REST) binds a neuronal cell type selective silencer element to mediate transcriptional repression of neuron-specific genes in non-neuronal cells and neuronal progenitors. Two repression domains (RD-1 and RD-2) occur in its N-terminal and C-terminal regions, respectively. RD-1 recruits mSin3 and HDAC, th

10. Plasticity of the cochleotopic (frequency) map in specialized and nonspecialized auditory cortices
Auditory conditioning (associative learning) causes reorganization of the cochleotopic (frequency) maps of the primary auditory cortex (AI) and the inferior colliculus. Focal electric stimulation of the AI also evokes basically the same cortical and collicular reorganization as that caused by conditioning. Therefore, part of the neural mechanism for the

11. Neural correlates of perceptual learning: A functional MRI study of visual texture discrimination
Visual texture discrimination has been shown to induce long-lasting behavioral improvement restricted to the trained eye and trained location in visual field [Karni, A. & Sagi, D. (1991) Proc. Natl. Acad. Sci. USA 88, 4966–4970]. We tested the hypothesis that such learning involves durable neural modifications at the earliest cortical stages of the visual

12. Functional reorganization and stability of somatosensory-motor cortical topography in a tetraplegic subject with late recovery
The functional organization of somatosensory and motor cortex was investigated in an individual with a high cervical spinal cord injury, a 5-year absence of nearly all sensory/motor function at and below the shoulders, and rare recovery of some function in years 6–8 after intense and sustained rehabilitation therapies. We used functional magnetic resonance
