1. Monitoring the Hearing Handicap and the Recognition Threshold of Sentences of a Patient with Unilateral Auditory Neuropathy Spectrum Disorder with Use of a Hearing Aid
Abstract Introduction Treatment for auditory neuropathy spectrum disorder (ANSD) is not yet well established, including the use of hearing aids (HAs). Not all patients diagnosed with ASND have access to HAs, and in some cases HAs are even contraindicated. Objective To monitor the hearing handicap and the recognition threshold of sentences in silence and

2. Involvement of midbrain tectum neurokinin-mediated mechanisms in fear and anxiety
Electrical stimulation of midbrain tectum structures, particularly the dorsal periaqueductal gray (dPAG) and inferior colliculus (IC), produces defensive responses, such as freezing and escape behavior. Freezing also ensues after termination of dPAG stimulation (post-stimulation freezing). These defensive reaction responses are critically mediated by γ-amin

3. Alterações no processamento da informação sensorial auditiva induzidas pela abstinência ao álcool em ratos: importância dos mecanismos GABAérgicos e glutamatérgicos do colículo inferior / Alterations in the Processing of the Auditory Sensorial Information Induced by the Abstinence to the Alcohol in Rats: Importance of the Mechanisms GABAérgicos and Glutamatérgicos of the Inferior Colliculus
A expressão de respostas de medo condicionadas e incondicionadas geradas por estímulos auditivos de natureza aversiva envolve a transmissão neural do colículo inferior (CI) para o núcleo geniculado medial do tálamo, principalmente através do seu núcleo central (CIc). Como outras drogas de abuso, o álcool atua em múltiplos alvos no cérebro produzin

4. Involvement of GABAergic mechanisms of the dorsal periaqueductal gray and inferior colliculus on unconditioned fear
The fact that the dorsal periaqueductal gray (dPAG) and inferior colliculus (IC), together with superior colliculus, medial hypothalamus and amygdala, constitute the brain aversion system has been well-established. Stepwise increases in the intensity of electrical stimulation of dPAG or IC cause freezing and escape responses, which are followed by a freezing

5. The maturational process of the auditory system in the first year of life characterized by brainstem auditory evoked potentials
The study of brainstem auditory evoked potentials (BAEP) allows obtaining the electrophysiological activity generated in the cochlear nerve to the inferior colliculus. In the first months of life, a period of greater neuronal plasticity, important changes are observed in the absolute latency and inter-peak intervals of BAEP, which occur up to the completion

6. Centros rombencefálicos de processamento auditivo do sagui (Callithrix jacchus): uma análise citoarquitetônica e neuroquímica
The auditory system is composed by a set of relays from the outer ear to the cerebral cortex. In mammals, the central auditory system is composed by cochlear nuclei, superior olivary complex, inferior colliculus and medial geniculate body. In this study, the auditory rombencephalic centers, the cochlear nuclear complex and the superior olivary complex were e

7. Agonistic-like responses from the torus semicircularis dorsalis elicited by GABA A blockade in the weakly electric fish Gymnotus carapo
Findings by our group have shown that the dorsolateral telencephalon of Gymnotus carapo sends efferents to the mesencephalic torus semicircularis dorsalis (TSd) and that presumably this connection is involved in the changes in electric organ discharge (EOD) and in skeletomotor responses observed following microinjections of GABA A antagonist bicuculline into

8. Envolvimento de receptores opióides µ1 e das redes neurais do colículo inferior na analgesia pós-ictal / Involvement of the µ1-opioid receptor-mediated system and inferior colliculus in the post-ictal analgesia
A antinocicepção é descrita como redução na capacidade de perceber a dor, sendo importante componente para o organismo, quando este está envolvido em situações de emergência. Muitos neurotransmissores e seus receptores estão envolvidos nas diversas formas de analgesia, como por exemplo, monoaminas, acetilcolina e opióides endógenos. A analgesia p

9. Combination sensitivity and processing of communication calls in the inferior colliculus of the Moustached Bat Pteronotus parnellii
Muitos animais usam gritos de comunicação complexos nos seus comportamentos sociais. Sabemos em algumas espécies quais parâmetros dos gritos estimulam determinados comportamentos, mas não entendemos como o sistema auditivo codifica os gritos. Tampouco entendemos os mecanismos subjacentes à seletividade neural aos gritos. Nossos estudos do mesencéfalo

10. GABAergic feedforward projections from the inferior colliculus to the medial geniculate body.
A novel and robust projection from gamma-aminobutyric acid-containing (GABAergic) inferior colliculus neurons to the media] geniculate body (MGB) was discovered in the cat using axoplasmic transport methods combined with immunocytochemistry. This input travels with the classical inferior colliculus projection to the MGB, and it is a direct ascending GABAergi
