Perirhinal cortical inactivation impairs object-in-place memory and disrupts task-dependent firing in hippocampal CA1, but not in CA3
Objects and their locations can associatively define an event and a conjoint representation of object-place can form an event memory. Remembering how to respond to a certain object in a spatial context is dependent on both hippocampus and perirhinal cortex (PER). However, the relative functional contributions of the two regions are largely unknown in object-place associative memory. We investig...
متن کاملVentral tegmental area disruption selectively affects CA1/CA2 but not CA3 place fields during a differential reward working memory task.
Hippocampus (HPC) receives dopaminergic (DA) projections from the ventral tegmental area (VTA) and substantia nigra. These inputs appear to provide a modulatory signal that influences HPC dependent behaviors and place fields. We examined how efferent projections from VTA to HPC influence spatial working memory and place fields when the reward context changes. CA1 and CA3 process environmental c...
متن کاملSynaptic plasticity supports slow gamma phase-locking in CA1 place cells during environmental novelty
Information processing and transfer between brain structures have been proposed to engage the phase-locking of neuronal firing to gamma oscillations during certain cognitive functions, including learning and memory. The cellular mechanism behind this precise temporal organisation of action potentials might rely on changes in synaptic strength. Kitanishi et al. (Kitanishi T, Ujita S, Fallahnezha...
متن کاملA sensitizing regimen of methamphetamine causes impairments in a novelty preference task of object recognition.
A neurotoxic regimen of methamphetamine impairs object recognition (OR) in rats. The present study investigated whether neurotoxicity is a necessary component of methamphetamine's effect on OR. Animals were exposed to a sensitizing regimen of methamphetamine, and were tested for OR one week, and locomotor behavior two weeks, later. Quantitative autoradiography was used to measure [(125)I]RTI-55...
متن کاملRecognition of Trademarks during Sport Television Broadcasts
In the paper the problem of the recognition of trademarks placed on banners which are visible during a sport television broadcast is described and experimentally investigated. It constitutes the second stage of the process of the analysis of the banners, e.g. in order to estimate the time that a particular banner is visible and can exert influence on the customers’ behaviour. Banners placed nea...
