Long Term Potentiation, Navigation & Dynamic Progamming
نویسندگان
چکیده
Blum andAbbott (1995) recently proposed an algorithm for learned navigation that is based on Hebbian changes to adaptive connections between place cells in the hippocampus. This paper suggests using a temporal difference rule (Sutton, 1988) for synaptic plasticity instead, and shows how this alters the resulting behaviour. It also recasts the problem of navigation into the reinforcement learning context of adaptive optimising control, and shows how to learn new trajectories that are not based only on averaging old ones.

Block of 5-HT2 Receptors Enhances Hippocampal Long-Term Potentiation
The effect of endogenous serotonin on long-term potentiation (LTP) in region CAI was studied by blocking 5-HT2 receptors with ketanserin in rat hippocampal slices. Such a block significantly en-hanced long-term potentiation of the CAI population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. This implies that serotonin acts on 5-HT2 receptors in CAI...
متن کاملLow-power density of 950 MHz radiation does not affect long-term potentiation in rat dentate gyrus
Introduction: Over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. This in vivo study was planned for evaluating the effects of whole-body exposure to 950 MHz field of GSM mobile phone system on rat dentate gyrus long-term potentiation. Materials and Methods: 24 naive male Wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...
متن کاملP3: Mechanisms of TrkB-Mediated Hippocampal Long-Term Potentiation in Learning and Memory
Long-term potentiation (LTP) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. Studies in recent years indicate the importance of molecular pathways in the development of memory and learning. Tropomyosin receptor kinase B (TrkB) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...
متن کاملA Model of Navigation in a Complex Maze Inspired by Hippocampus
A model of navigation inspired by rodent hippocampus stores several navigational maps in a single attractor (Hopfield-like) neural network. Hippocampus is a part of brain involved in spatial orientation. It models such phenomena as place cells, long-term potentiation, long-term depression, path integration, inhibitory interneurons etc. Structure of the model conforms to functional schema of hip...
متن کاملThe effects of CCK-8S on spatial memory and long-term potentiation at CA1 during induction of stress in rats
Objective(s): Cholecystokinin (CCK) has been proposed as a mediator in stress. However, it is still not fully documented what are its effects. We aimed to evaluate the effects of systemic administration of CCK exactly before induction of stress on spatial memory and synaptic plasticity at CA1 in rats. Materials and Methods: Male Wistar rats were divided into 4 groups: the control, the control-C...
