The understanding of fundamental neurological processes that enables the brain to analyze good learning produces physical changes in brain. The use of several regions of brain in the learning process and problem solving techniques are discussed.

By integrating previous computational models of corticohippocampal function, the authors develop and test a unified theory of the neural substrates of familiarity, recollection, and classical conditioning. This approach integrates models from 2 traditions of hippocampal modeling, those of episodic memory and incremental learning, by drawing on an…

Benzodiazepines have been useful tools for investigating mechanisms underlying learning and memory. The present set of experiments investigates the role of hippocampal GABA[subscript A]/benzodiazepine receptors in memory consolidation using Pavlovian fear conditioning. Rats were prepared with cannulae aimed at the dorsal hippocampus and trained…

The prefrontal cortex of the primate frontal lobes provides the capacity for judgment which can constantly adapt behavior in order to optimize its outcome. Adjudicating between long-term memory programs and prepotent responses, this capacity reviews all incoming information and provides an interpretation dependent on the events that have just…

Discussion of the concepts of learning and training focuses on how to incorporate the whole brain in the learning process when personalizing electronic learning. Suggests that trainers will need to learn teaching strategies that embrace the right brain's need for time and space to examine, contemplate, integrate, and utilize information.…

This paper reviews a body of work conducted in our laboratory that applies functional magnetic resonance imaging (fMRI) to better understand the biological response and change that occurs during prototype-distortion learning. We review results from two experiments (Little, Klein, Shobat, McClure, & Thulborn, 2004; Little & Thulborn, 2005) that…

Most trainers believe there are just two scientific approaches on which to base a training technology: behavioral psychology and cognitive psychology. There is a third scientific approach currently emerging that does deal with every kind of skill, and it comes from biology rather than psychology. This new approach is based on findings from…

Studies with Nootropic psychoactive drugs (such as Piracetam) suggest that Piracetam lacks significant side effects; promotes memory and learning; and improves the reading ability of dyslexics, possibly by directly affecting the left-brain hemisphere. Results are contrasted with studies showing the lack of effectiveness of intensive teaching.…

Kolb's Experiential Learning Model suggests that people differ in how they perceive and process information. Public agency training should incorporate knowledge of brain hemisphere dominance and learning style preferences in training design. (SK)

Synapses formed by the olfactory nerve (ON) provide the source of excitatory synaptic input onto mitral cells (MC) in the olfactory bulb. These synapses, which relay odor-specific inputs, are confined to the distally tufted single primary dendrites of MCs, the first stage of central olfactory processing. Beta-adrenergic modulation of electrical…

Lesions of the basolateral amygdala (BLA) have long been associated with abnormalities of taste-related behaviors and with failure in a variety of taste- and odor-related learning paradigms, including taste-potentiated odor aversion, conditioned taste preference, and conditioned taste aversion. Still, the general role of the amygdala in…

Voltage-gated potassium channels (Kv) are critically involved in learning and memory processes. It is not known, however, whether the expression of the Kv1.1 subunit, constituting Kv1 channels, can be specifically regulated in brain areas important for learning and memory processing. Radioactive in situ hybridization was used to evaluate the…

Hebbian learning is a biologically plausible and ecologically valid learning mechanism. In Hebbian learning, "units that fire together, wire together". Such learning may occur at the neural level in terms of long-term potentiation (LTP) and long-term depression (LTD). Many features of Hebbian learning are relevant to developmental theorizing,…

The article reviews the literature on creativity, learning styles, brain studies, teaching technologies, and learning strategies. Although learning styles and strategies differ among individuals, creativity is maximized through use of the fully functioning brain. Teaching suggestions include producing alternative explanations/consequences,…

Nonreinforced retrieval can cause extinction and/or reconsolidation, two processes that affect subsequent retrieval in opposite ways. Using the Morris water maze task we show that, in the rat, repeated nonreinforced expression of spatial memory causes extinction, which is unaffected by inhibition of protein synthesis within the CA1 region of the…
