Functional Dissection of Brainstem Circuitry
… systems, which are principally located in the brainstem. These different brainstem neural populations, while performing apparently simple life sustaining functions, are remarkably complex. For proper function, survival circuits need to receive information from brain regions responsible for …

Maturation of GABAergic signaling during brainstem development
Im adulten Zentralnervensystem wirkt γ-Aminobuttersäure (GABA) als hemmender Neurotransmitter über ligandgesteuerte GABAA-Rezeptorkanäle und G-proteingekoppelte GABAB-Rezeptoren. Neue Studien haben aber gezeigt, dass während der Entwicklung GABA im frühpostnatalen ZNS auch exitatorisch wirken kann. …

Genomic and Molecular Characterization of Brainstem Glioma
<p>Gliomas of the brainstem and closely surrounding structures are a devastating form of brain cancers with some of the highest mortality rates among all cancers. The delicate structures surrounding these tumors make surgical resection rare due to the risk of perioperative mortality or paralysis. A …

Focused ultrasound-mediated drug delivery to the brainstem
<p>Brainstem gliomas are tumors that occur in the brainstem, the brain region that connects the brain to the spinal cord and controls vital body functions. The critical anatomic location of the brainstem precludes surgical intervention and limits the use of invasive therapeutic techniques. …

Precise Temporal Processing in the Gerbil Auditory Brainstem
… paths in the ascending auditory pathway. At the brainstem level, several structures are involved, which are known to serve different well-defined functions. However, the function of one prominent brainstem nucleus, the rodent superior paraolivary nucleus (SPN) is unknown. Two hypotheses have been …

Brainstem cholinergic modulation of the limbic learning circuit
… In Experiment 2, bilateral lesions in the brainstem laterodorsal tegmental (LDT) and pedunculopontine tegmental (PPT) nuclei, a primary source of AV thalamic cholinergic afferents, retarded acquisition of the avoidance response and attenuated excitatory TIA in the AV nucleus and posterior …

Modules in the brainstem and spinal cord underlying motor behaviors
… I have addressed the question whether the brainstem and spinal cord are involved in structuring and combining muscle synergies in order to execute a range of natural movements. The strategy to investigate this question was to analyze the electromyogram (EMG) data recorded from the leg …

Plasticity of Brainstem Motor Systems in Response to Developmental Nicotine Exposure
… shown that DNE alters nAChR function in multiple brainstem regions (Pilarski et al., 2012, Wollman et al, 2016). Moreover, DNE causes multiple changes to XIIMNs, which innervate the muscles of the tongue (Powell et al., 2016, Powell et al., 2015, Pilarski et al., 2011). These changes likely …

Auditory brainstem and middle-latency responses with optimized stimuli: experiments and models
… processing for the formation of auditory brainstem and middle latency responses (ABR and MLR). The main emphasis is put on the development and evaluation of an optimized (chirp) stimulus based on the concept of compensation for travel time differences along the basilar membrane. In Ch. 2 …

Auditory brainstem response latency in noise as a marker of cochlear synaptopathy
… synaptopathy reduces the amplitude of auditory brainstem response (ABR) wave-I. Unfortunately, ABR wave-I is difficult to measure in humans, limiting its clinical use. Here, using behavioral, otoacoustic, and electrophysiological measures in humans and mice in conjunction with computational …

Image Processing Considerations for High Resolution Diffusion Tensor Imaging of the Human Brainstem
… of white matter in the brain. The human brainstem has many white matter tracts that connect small nuclei in the brainstem to other regions of the brain. High resolution DTI of the brainstem may be helpful in understanding diseases that implicate brainstem nuclei. There are technical …

Real-time detection of auditory : steady-state brainstem potentials evoked by auditory stimuli
The auditory steady-state response (ASSR) is advantageous against other hearing techniques because of its capability in providing objective and frequency specific information. The objectives are to reduce the lengthy test duration, and improve the signal detection rate and the robustness of the …

Outcomes of Auditory Brainstem Implantation in Adults with Postlingual Deafness: A Systematic Review
<p><strong>Objective:</strong>The purpose of this investigation is to conduct a systematic review of the long-term speech-recognition outcomes of ABIs in postlingually deafened adults, and to compare outcomes of ABIs in adults with NF2/tumors to adults without NF2.<strong> </strong></p> …

Functional Magnetic Resonance Imaging of Peripheral Neuropathic Pain in the Spinal Cord and Brainstem
… caudal areas (such as the spinal cord (SC) or brainstem) have used only experimental models of pain. The objectives of this study were 1) to determine the neural activity in the human brainstem and SC that is caused by a noxious mechanical stimulus and 2) to compare the neural response to …
