Search for a threatening target triggers limbic guidance of spatial attention.
24 Aug 2009 
The ability to actively locate potential threats in our environment is highly adaptive. To investigate mediating neural mechanisms, we designed a visual search task in which central cues signaled future location and emotional expression (angry or ...

24 Aug 2009 Synaptic inhibition plays an important role in shaping receptive field (RF) properties in the visual cortex. However, the underlying mechanisms remain not well understood, partly because of difficulties in systematically studying functional ...

Human hippocampal CA1 involvement during allocentric encoding of spatial information.
24 Aug 2009 A central component of our ability to navigate an environment is the formation of a memory representation that is allocentric and thus independent of our starting point within that environment. Computational models and rodent electrophysiological ...

Role of dentate gyrus in aligning internal spatial map to external landmark.
23 Aug 2009 Humans and animals form internal representations of external space based on their own body movement (dead reckoning) as well as external landmarks. It is poorly understood, however, how different types of information are integrated to form a unified ...

Preventive effects of Chlorella on cognitive decline in age-dependent dementia model mice.
19 Aug 2009 Oxidative stress is one of the major causes of age-dependent memory loss and cognitive decline. Cytotoxic aldehydes are derived from lipid peroxides and their accumulation may be responsible for age-dependent neurodegeneration, including Alzheimer's ...

17 Aug 2009 BACKGROUND: While there is a general agreement that picture-plane inversion is more detrimental to face processing than to other seemingly complex visual objects, the origin of this effect is still largely debatable. Here, we address the question of ...

Stimulus ensemble and cortical layer determine V1 spatial receptive fields.
15 Aug 2009 The concept of receptive field is a linear, feed-forward view of visual signal processing. Frequently used models of V1 neurons, like the dynamic linear filter static nonlinearity Poisson spike encoder model, predict that receptive fields measured ...

The elevator illusion results from the combination of body orientation and egocentric perception.
12 Aug 2009 Perception of body orientation and apparent location of objects are altered when humans are using assisted means of locomotion and the resultant of the imposed acceleration and gravity is no longer aligned with the gravitational vertical. As the ...

The geometry of perisaccadic visual perception.
10 Aug 2009 Our ability to explore our surroundings requires a combination of high-resolution vision and frequent rotations of the visual axis toward objects of interest. Such gaze shifts are themselves a source of powerful retinal stimulation, and so the ...

Shift from hippocampal to neocortical centered retrieval network with consolidation.
10 Aug 2009 The standard model of system-level consolidation posits that the hippocampus is part of a retrieval network for recent memories. According to this theory, the memories are gradually transferred to neocortical circuits with consolidation, where the ...
