Reports the detection of magnetic fields associated with the flow of electric current in the human brain in response to electrical stimulation of the fingers. (SL)

In response to a previous article proposing perceptual reinforcement of stereotyped movements in autistic and mentally retarded persons, it is argued that this theory fails to take into account biological findings and theory regarding pathological stereotyped acts. An alternative theory derived from neurological concepts is suggested. (Author/DB)

Reports that people who are predominantly left-handed apparently are able to withstand moderate brain damage with relatively few of the motor problems observed in right-handed victims of brain damage. Other brain-related differences between left- and right-handed individuals are also noted. (JN)

Assesses proposed new demographic information formulas for estimating premorbid Wechsler Adult Intelligence Scales-Revised Intelligence Quotient scores. Investigated cross-validation of this index on a neurologically normal but clinically relevant criterion group and determined the neuropsychological utility of the formulas to discriminate between…

The article examines recent developments in seizure mechanisms and management in young children. Emphasis is directed toward neurodevelopmental sequelae and important genetic/environmental influences. (Author)

Engineers seeking to develop intelligent computers have looked to studies of the human brain in hope of imitating its processes. A theory (known as cooperative action) that the brain processes information with electromagnetic waves may inspire engineers to develop entirely new types of computers. (JN)

The article examines neuropsychological theories of behavior and considers their application to special education, with particular emphasis on learning disabilties. Among problems involved with the approach are difficulties communicating educationally relevant data and confusion over the validity and utility of the neuropsychological approach. (CL)

Discusses research that indicates that nerve membranes, which play a key role in the conduction of impulses, are traversed by protein channels with ion pathways opened and closed by the membrane electric field. (Author/MLH)

Mirror-imaging of letter shapes and reversals of whole words when read or written are defined and explanations are given as to why children tend to make these mistakes. (KW)

Surveys Dissertation Abstracts'', lists of neuroscientists, and grants awarded by the National Institutes of Mental Health for the 1960's, and identifies the 75 institutions, most graduating Ph.D's in the neurosciences. The relatively greater increase in these degrees than for all bioscience doctorates should be considered in planning doctoral…

Various human mental activities are examined, a theory of brain function presented, and the possible nature of the ultra-intelligent machine" suggested. Some of the social repercussions of such machines are briefly discussed. (AL)

Results of studies with undernourished guinea pig mothers and their offspring suggest that adequate postnatal nutrition can offset some, but not all of the brain biochemical changes resulting from fetal undernutrition. (Author/KW)
