Auditory evoked cortical responses (AECR) were studied in 15 children, 8- to 15-years of age, classified as normal dextrals, retarded dextrals, or retarded sinistrals, to develop an index for differential diagnosis of mental retardation based upon normal asymmetry in amplitude of the AECR in the left and right hemispheres.

A report which describes a theory and corresponding model for the neural basis of language. A detailed functional description is given for elementary visual-linguistic processes. (Author)

Chemical actions in the brain result in cognitive, emotional, neuroendocrine, neuromuscular, and/or neurocirculatory effects. Developments in understanding brain chemistry are discussed, considering among others, neurotransmitter chemistry, neuropeptides, drugs and the brain, antidepressants, and actions of minor tranquilizers. (JN)

Discusses the process of aging in the brain, including some of the structural and chemical changes that take place in the nerve cells as they age. (CS)

Discusses recent brain research as it pertains to reading instruction. (DD)

Analysis of event-related potentials associated with detected targets in a vigilance task showed that a negative component (N2) covaried in latency with reaction time. These results support the hypothesis that N2 reflects a decision process which controls behavioral responses in sensory discrimination tasks. (BB)

Presents a paper that relates human behaviors, such as pleasure, pain, learning, and speech to specific anatomical areas of the brain. (MLH)

Presents the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research guidelines for performing psychosurgery. Also includes dissenting arguments of commission members favoring a total ban of psychosurgery. (SL)

Reviews what is known about the neurobiology of learning and then considers the future. Augments the neurobiological analysis with a series of implications and reservations about their use and the social factors in their use which may interact with them. (Editor/RK)

The relationship between physiological learning theory and the school-aged child with minimal brain damage is explored. (Author/SBH)

On the basis of a search of the literature and extensive inquiries to clinicians, cases that contained any information concerning possible neuropathologic changes in cases of childhood autism or psychosis were catalogued. (Author/SBH)

Today, researchers can learn about blood flow, electromagnetic fields, and chemical composition of the brain by using functional MRI (magnetic resonance imaging). As biologists, medical researchers, and cognitive scientists learn more about brain functions, educators must keep informed, study, and apply what they have learned in the classroom.…
