Estrogenic modulation of place and response learning via specific receptor-mediated mechanisms
… has shown that estrogens indeed modulate learning and memory. Importantly, estrogens do not globally improve cognition but have bi-directional effects depending on the cognitive task and neural systems engaged. Estrogens generally enhance learning and memory for tasks that are sensitive to …

Estradiol Has Distinct Effects on the Hippocampal and Striatal Memory Systems
… of estradiol in the hippocampus to enhance place learning and in the striatum to impair response learning. By altering the responsiveness of hippocampal and striatal cells to experience, estradiol biases the type of information obtained, resulting in enhanced or impaired learning depending on the …

Range expansion in the invasive Round goby (Neogobius melanostomus): behavioural and gene transcriptional components of a successful invader
… traits specific to aggression, boldness, stress response, learning, and activity; and 3) how behaviour and gene transcription vary between residents and dispersers and detection time since North American invasion. I found that round goby possess an “invasion behavioural phenotype” consisting of …

The influence of the trait-like tendency to rely on declarative- or procedural- like memory systems on the development of habits and compulsive behaviours in the rat
… place or a procedural-like, egocentric response spatial learning strategy, a “direct opposition” probe can reveal which strategy any individual relies on to solve the task. The distinction among declarative and procedural memory parallels, but is not identical to, the distinction among …

Acetylcholine Regulation of the Hippocampus and Striatum During Learning
… activity in the hippocampus regulates place learning, (b) cholinergic activity in the striatum regulates response learning and (c) cholinergic activity in one structure regulates competitive interactions with the other. To this end, rats were tested in tasks in which acquisition of either …

Region-specific Mechanisms of Estrogen and Age on Neuronal Ensemble Activity During Spatial Navigation
… The presence of circulating estradiol enhances learning on tasks that require the use of a hippocampus-dependent place strategy and impairs learning on tasks that require the use of a dorsal striatum-dependent response strategy. When either strategy may be used successfully, estradiol biases …

Changes in the firing patterns in neurons of the sensorimotor striatum during learning : what changes and why
… striatum, have been implicated in stimulus-response learning. Here, I analyze the role the striatum plays in learning. We recorded from neurons of the sensorimotor striatum as rats learn, are over-trained, are extinguished, and are re-trained on a discriminative T-maze task. In this T-maze a …

Use it and boost it: cognitive and physical activities modulate cognition via BDNF-TrkB signaling
… enhance hippocampus- and striatum-sensitive learning via BDNF-TrkB signaling. In addition, we found that physical activity increases BDNF release in the striatum before and during task learning and in the hippocampus during task learning. To further identify the cell signaling mechanisms …

Investigations into controllers for adaptive autonomous agents based on artificial neural networks.
… a unified architecture integrating sensorimotor learning and overall control. This was intended to overcome shortcomings of typical behaviour-based approaches in reactive control settings. It was achieved in two stages. Initially, feedforward neural networks were used at the sensorimotor level of …
