Spatial representation in the hippocampal formation of birds

09/02/2017The representation of space in the hippocampal formation has been studied extensively over the past four decades, culminating in the 2014 Nobel Prize in Physiology or Medicine. However, an important question remained unresolved: Is the role of this brain structure in spatial processing restricted to mammals, or can we find its origins in other classes

Visual Search: Behavioral Experiments

Setup for visual search behavioral experiments

23/12/2015Visual Search: Behavioral Experiments Animals actively scan the environment to collect useful bits of information. This process, known as visual search, is highly studied in humans and animals. What attracts the visual gaze and how barn owls search for interesting stimuli are the main questions asked in this project. We combine kinematic measurements of head movements

Visual Search: Physiological Experiments

23/12/2015Visual Search: Physiological Experiments The saliency of visual objects is based on the center to background contrast. Particularly objects differing in one feature from the background may be perceived as more salient. It is not clear to what extent this so called ‘‘pop-out’’ effect observed in humans and primates governs saliency perception in non-primates as

Habituation

habituation project

26/12/2003Habituation Habituation is the most basic form of memory, yet very little is known about its underlying mechanisms. Given the assumed role of the gaze control system in stimulus selection (see section 2) and the direct link between habituation and stimulus selection, we assume that the gaze control system is involved in habituation. We

Auditory map development

Auditory map development in barn owls

20/12/2002Auditory map development The neural mechanisms that generate internal representations of the auditory space have been extensively studied, indicating the importance of precise integration, in time and space, of information from the two ears and from different frequency bands. However, the important question of how the specific neural connections are formed remained unsolved. Are these

Visual-auditory processing

cover page image from J Of neurophysiology

26/12/2001Visual-auditory processing Visual and auditory information is integrated in the brain to facilitate the perception of events that can be both seen and heard. The barn owl, with its excellent visual and auditory capabilities, provides an interesting case study for the mechanisms of visual auditory integration. Moreover, it was shown in barn owls that interactions

Stimulus Specific adaptation and target selection

Stimulus Specific adaptation and target selection

26/12/2000Stimulus Specific adaptation and target selection Stimulus specific adaptation (SSA) is a phenomenon at the neural level, proposed as the neural correlate of novelty detection. In SSA a rare stimulus elicits a stronger response than a frequent stimulus. Novelty is an important component of stimulus saliency and has been linked with the ability of animals
