The [delta] subunit of the GABA[subscript [Alpha]] receptor (GABA[subscript [Alpha]]R) is highly expressed in the dentate gyrus of the hippocampus. Genetic deletion of this subunit reduces synaptic and extrasynaptic inhibition and decreases sensitivity to neurosteroids. This paper examines the effect of these changes on hippocampus-dependent trace…

Despite a long history and considerable study, leadership remains a notoriously perplexing and enigmatic phenomenon. Although the "new leadership" perspective has revived convictions and general interest in leadership studies, conceptual and methodological problems nevertheless remain a feature of the research and theory-building terrain, and some…

This study represents a beginning step in research that may ultimately show that the multitudes of human behavior that educators currently encounter may be reduced to three broad human attributes: arousal, affect, and cognition. The resulting simplicity should lead to improved understanding and better decision making by practitioners. Four…

For many children, especially those with reading difficulties, a motor-kinesthetic learning activity may be an effective tool to teach complex concepts. With this in mind, the authors developed and tested a game designed to teach fourth- to sixth-grade children some basic principles of nervous system function by allowing the children themselves to…

The brain is a truly fascinating structure! It controls the body and allows everyone to think, learn, speak, move, feel, remember, and experience emotions. Although the brain is a single organ, it is very complex and has several regions, each having a specific function. These functionally diverse regions work together to allow for coordination of…

Our facial expressions give others the opportunity to access our feelings, and constitute an important nonverbal tool for communication. Many recent studies have investigated emotional perception in adults, and our knowledge of neural processes involved in emotions is increasingly precise. Young children also use faces to express their internal…

Objective: Psychotherapy and biological psychiatry remain divided in psychiatry residency curricula. Behavioral neurobiology and neuropsychiatry provide a systems-level framework that allows teachers to integrate biology, psychodynamics, and psychology. Method: The authors detail the underlying assumptions and outline of a neural systems-based…

The previous article in this series introduced the triune brain, the three components of which handle specialized life tasks. The survival brain, or brain stem, directs automatic physiological functions, such as heartbeat and breathing, and mobilizes fight/flight behaviour in times of threat. The emotional (or limbic) brain activates positive or…

The aim of this study was to characterize the distribution, timing, and risk factors for psychiatric comorbidity in children with recent onset epilepsy. Children aged 8 to 18 years with recent onset epilepsy (less than 1 year in duration) of idiopathic etiology (n=53) and a healthy comparison group (n=50) underwent a structured psychiatric…

Centers on the opinions of Michael Lawlor of the Society for Effective Affective Learning (S.E.A.L.) about "right brain" language learning and includes suggestions (with examples presented about learning Greek) for developing one's power of suggestion and applying it to foreign language learning.

Describes some of the common principles underlying the operation of the cortex in an effort to understand the human brain. Discusses the structure of the cortex, its specific areas, and its map-making abilities. Describes some of the recent discoveries about brain operation, development and functioning. (TW)

Argues against the theory of hemispheric dominance and discusses the dangers of developing an educational system based on the false assumptions of two-brain theories. (SRT)

An alternative way of attempting to understand visual hemispheric specialization is presented. A theory of certain high-level processing subsystems is formulated in light of an analysis of problems that must be solved by the visual system and the constraints on the solutions to these problems. (Author/LMO)

Provides background information and research findings on right and left brain hemisphere research. The cerebral hemisphere, research on split-brain subjects, research with normal subjects, and sex differences are addressed. Indicates that each hemisphere functions differently (left--verbal and analytical; right--spatial and perceptual) but both…

Research identifies two interrelated memories--one that retains facts and symbols and one that retains motor and problem-solving skills. These and other findings challenge educators to determine what students should memorize, to help them move from random memorization to creating useful concepts, and to teach students to use memory in problem…
