The author describes three techniques for developing conscious awareness of the responses and behaviors of the right parietal lobe through describing a right brain related impression aloud in sensory image terms of color, shape, and texture. (CL)

The results showed that all the Ss had normal hearing on the monaural speech tests; however, there was indication of central auditory nervous system dysfunction in the language dominant hemisphere, inferred from the dichotic tests, for those Ss displaying echolalia. (Author)

Describes several methods by which an amateur might prepare a laser light display in the home or the classroom. Methods described include the use of particles in lasers, filters, reflecting laser beams, vibration's effects on laser beams, rotating mirrors, and the use of prisms with laser beams. (DS)

Maze learning was used with preschool children to test the hypothesis that the hippocampus (a distinctive cortical structure) in the human brain matures at about four to five years of age. (JMB)

The article examines the fuctions of neurological and environmental variables in learning disabilities (LD). A behavior sequence approach is described which provides for the integration of both neurological and environmental variables. Implications of this approach for three categories of children (LD--no neurological dysfunction, no…

This article is adapted from the author's book "The Brain: The Last Frontier," and discusses recent research on the brain that establishes that the brains of boys and girls develop differently and that this affects their learning. (Author/MLF)

Used various measures to examine neuropsychology of depression in terms of organic and motivational hypotheses among 30 medication-free depressed outpatients and 30 nondepressed controls. A 2 x 2 (diagnosis x motivational level) multivariate analysis revealed significant main effect for depression, but no effect for motivation and no interaction.…

The influence of behaviorism's methods and theories on theory and research in the neurosciences is examined, partly in light of John B. Watson's 1913 essay. An attempt is made to reconcile classical behaviorism and modern cognitive psychology and neuroscience. (SLD)

Examines the role of cerebrospinal fluid (CSF), a clear, colorless liquid that constantly bathes the brain and spinal cord. Scientists argue that cerebrospinal fluid carries important signals for sleep, appetite, and sex. Evaluates past and current research documenting the purpose of cerebrospinal fluid in the brain. (CCM)

Explores how experiences after birth exert a dramatic and precise impact, physically determining how the intricate neural circuits of the brain are wired, in particular, in areas of language and vocabulary. Discusses the brain's acute vulnerability to trauma such as under or over stimulation or abuse. (HTH)

Brain research is complicated, but its message is simple: babies are born learning and what they learn is up to us. New research on infant brain development shows that a child's experiences in the first three years of life have a distinct impact on her later development and learning. Here's why. All babies are born with one organ that is not fully…

Foraging-and feeding-related behaviors across eumetazoans share similar molecular mechanisms, suggesting the early evolution of an optimal foraging behavior called area-restricted search (ARS), involving mechanisms of dopamine and glutamate in the modulation of behavioral focus. Similar mechanisms in the vertebrate basal ganglia control motor…

Positron emission tomography was used to investigate two competing hypotheses about the role of the left inferior frontal gyrus (IFG) in word generation. One proposes a domain-specific organization, with neural activation dependent on the type of information being processed, i.e., surface sound structure or semantic. The other proposes a…

Psychologists and neuroscientists have had a long-standing interest in the P3, a prominent component of the event-related brain potential. This review aims to integrate knowledge regarding the neural basis of the P3 and to elucidate its functional role in information processing. The authors review evidence suggesting that the P3 reflects phasic…

The forebrain cholinergic neurons are localized in the nucleus basalis magnocellularis (NBM), the major source of cholinergic innervation to the neocortex and to the amygdala, and in the medium septum-banda diagonalis complex, which provides cholinergic inputs to the hippocampus (Mesulam et al. 1983; Woolf et al. 1984; Nicoll 1985). Basic and…
