Investigating human memory of self-position using a virtual 3-dimensional visual environment
(Association for Research in Vision and Ophthalmology (ARVO), 2016-09-01)Knowing one's location in space is crucial for navigation, especially in unknown environments. Recently, systems involved in self-localization for spatial navigation have been found in rodent brains, but the mechanisms for ... -
When wanting to change is not enough: automatic appetitive processes moderate the effects of a brief alcohol intervention in hazardous-drinking college students.
(2012-12-07)BACKGROUND: Research indicates that brief motivational interventions are efficacious treatments for hazardous drinking. Little is known, however, about the psychological processes that may moderate intervention success. ... -
Segregation of cortical head direction cell assemblies on alternating theta cycles
(Nature Publishing Group, 2013-06-01)High-level cortical systems for spatial navigation, including entorhinal grid cells, critically depend on input from the head direction system. We examined spiking rhythms and modes of synchrony between neurons participating ... -
The multiple hit hypothesis for Gulf War illness: self-reported chemical/biological weapons exposure and mild traumatic brain injury
(MDPI, 2018-11-01)The Gulf War Illness Consortium (GWIC) was designed to identify objective biomarkers of Gulf War Illness (GWI) in 1991 Gulf War veterans. The symptoms of GWI include fatigue, pain, cognitive problems, gastrointestinal, ... -
Towards a neural-level cognitive architecture: modeling behavior in working memory tasks with neurons
(2019)Constrained by results from classic behavioral experiments we provide a neural-level cognitive architecture for modeling behavior in working memory tasks. We propose a canonical microcircuit that can be used as a building ... -
Comparison of properties of medial entorhinal cortex layer II neurons in two anatomical dimensions with and without cholinergic activation
(Public Library Of Science, 2013-09-12)Mechanisms underlying grid cell firing in the medial entorhinal cortex (MEC) still remain unknown. Computational modeling studies have suggested that cellular properties such as spike frequency adaptation and persistent ... -
Perception, cognition, and action in hyperspaces: implications on brain plasticity, learning, and cognition
(2019)We live in a three-dimensional (3D) spatial world; however, our retinas receive a pair of 2D projections of the 3D environment. By using multiple cues, such as disparity, motion parallax, perspective, our brains can construct ... -
Differences in visual-spatial input may underlie different compression properties of firing fields for grid cell modules in medial entorhinal cortex
(Public Library Of Science, 2015-11-01)Firing fields of grid cells in medial entorhinal cortex show compression or expansion after manipulations of the location of environmental barriers. This compression or expansion could be selective for individual grid cell ... -
Does layer 5 of the cortex project to the thalamic reticular nucleus? Implications for core and matrix thalamocortical circuits and sleep spindles
(2019-10-20)Two distinct thalamocortical (TC) circuits with reciprocal components can be identified in mammals: The core TC circuit, prevalent in sensory thalamus, drives activity focally in the middle cortical layers. In turn, these ... -
Rapid presentation rate negatively impacts the contiguity effect in free recall
(2019)It is well-known that in free recall participants tend to recall words presented close together in time in sequence, reflecting a form of temporal binding in memory. This contiguity effect is robust, having been observed ...
