Interaction between Facilitation and Depression at a Large CNS Synapse Reveals Mechanisms of Short-Term Plasticity

Ralf Schneggenburger, Olexiy Kochubey, Martin Guillermo Mueller

The two fundamental forms of short-term plasticity, short-term depression and facilitation, coexist at most synapses, but little is known about their interaction. Here, we studied the interplay between short-term depression and facilitation at calyx of Hel ...

Where sound position influences sound object representations: A 7-T fMRI study

Rolf Gruetter, Wietske Van der Zwaag, Stephanie Clarke

Evidence from human and non-human primate studies supports a dual-pathway model of audition, with partially segregated cortical networks for sound recognition and sound localisation, referred to as the What and Where processing streams. In normal subjects, ...

Sound-driven modulation of sub- and suprathreshold activity in mouse primary visual cortex

Diego Ghezzi

Integration of multimodal information is essential for the integrative response of the brain and is thought to be accomplished mostly in sensory association areas. However, available evidences in humans and monkeys indicate that this process begins already ...

Control of Exocytosis by Synaptotagmins and Otoferlin in Auditory Hair Cells

Ralf Schneggenburger

In pre-hearing mice, vesicle exocytosis at cochlear inner hair cell (IHC) ribbon synapses is triggered by spontaneous Ca2+ spikes. At the onset of hearing, IHC exocytosis is then exclusively driven by graded potentials, and is characterized by higher Ca2+ ...

Anesthesia prevents auditory perceptual learning

Michael Herzog, Alain Farron, Elisa Tartaglia, Carl Kristoffer Aberg

BACKGROUND: An auditory perceptual learning paradigm was used to investigate whether implicit memories are formed during general anesthesia. METHODS: Eighty-seven patients who had an American Society of Anesthesiologists physical status of I-III and were s ...

Functional connectivity and alterations in baseline brain state in humans

Roberto Martuzzi

This work examines the influence of changes in baseline activity on the intrinsic functional connectivity fMRI (fc-fMRI) in humans. Baseline brain activity was altered by inducing anesthesia (sevoflurane end-tidal concentration 1%) in human volunteers and ...

Gender bending: auditory cues affect visual judgements of gender in biological motion displays

Olaf Blanke

The movement of an organism typically provides an observer with information in more than one sensory modality. The integration of information modalities reduces the likelihood that the observer will be confronted with a scene that is perceptually ambiguous ...

The anatomy of object recognition - visual form agnosia caused by medial occipitotemporal stroke

Johannes Rüter

The influential model on visual information processing by Milner and Goodale (1995) has suggested a dissociation between action- and perception-related processing in a dorsal versus ventral stream projection. It was inspired substantially by the observatio ...

Local landmark-based registration for fMRI group studies of nonprimary auditory cortex

Jean-Philippe Thiran, Reto Meuli, Dragana Viceic, Ruth Campos Casillas

Interindividual functional and structural brain variability is a major problem in group studies, in which very focal activations are expected. Architectonic studies have shown that the human primary auditory area, which is located with a great constancy on ...

Perceptual and semantic contributions to repetition priming of environmental sounds

Roberto Martuzzi, Stephanie Clarke

Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming ...
