Behavioral and Neural Mechanisms of Overgeneralization in Anxiety
Overgeneralization of dangerous stimuli is a possible etiological account for anxiety disorders, yet the underlying behavioral and neural origins remain vague. Specifically, it is unclear whether this is a choice behavior in an unsafe environment ("better safe than sorry") or also a fundamental change in how the stimulus is perceived. We show that anxiety patients have wider generalization for ...
متن کاملNeural and behavioral mechanisms of olfactory perception.
Recent in vivo and in vitro studies have challenged existing models of olfactory processing in the vertebrate olfactory bulb and insect antennal lobe. Whereas lateral connectivity between olfactory glomeruli was previously thought to form a dense, topographically organized inhibitory surround, new evidence suggests that lateral connections may be sparse, nontopographic, and partly excitatory. O...
متن کاملDenoising Autoencoders for Overgeneralization in Neural Networks
Despite the recent developments that allowed neural networks to achieve impressive performance on a variety of applications, these models are intrinsically affected by the problem of overgeneralization, due to their partitioning of the full input space into the fixed set of target classes used during training. Thus it is possible for novel inputs belonging to categories unknown during training ...
متن کاملBehavioral and Neural Mechanisms of Homing and Migration in Birds
The extraordinary navigational ability of birds has fascinated natural historians for as long as animal behavior has been of interest. Successful navigation in birds is based first on an ability to determine directions in space (compass sense), relying on the sun, stars and earth's magnetic field. This compass sense promotes the development of an ability to determine relative location in space ...
متن کاملNeural and behavioral mechanisms of proactive and reactive inhibition.
Response inhibition is an important component of adaptive behavior. Substantial prior research has focused on reactive inhibition, which refers to the cessation of a motor response that is already in progress. More recently, a growing number of studies have begun to examine mechanisms underlying proactive inhibition, whereby preparatory processes result in a response being withheld before it is...
