The article reports on the resolution of the U.S. Congress to re-investigate the assassination of John F. Kennedy in Dallas, Texas on November 22, 1963. It mentions that a congressional subcommittee is looking for precise information of what the Federal Bureau of Investigation (FBI) and the Central Intelligence Agency (CIA) withheld from the Warren Commission's investigation. It also mentions that the CIA & Mafia conspiracies to assassinate Fidel Castro of Cuba, has brought about the suspicion from the public that the same entities has something to do with the assassination of the president.

The article offers information on the prevalence, diagnosis and prevention of hypertension, a medical term which is also known as high blood pressure, in the U.S. According to the American Heart Association (AHA), about 23 million of Americans are suffering from the disease in 1975, but the most alarming situation is that only half of them know that they are hypertensives. It states that it is one of nation's leading cause of death which killed 200,000 people in the year. Professor John Henry Laragh mentions that this quiet disease can be prevented if detected earlier. It also notes several factors associated with hypertension including obesity, heredity and diet.

The article focuses on the psychic phenomena in the U.S. and abroad. It states that the book "The Secret Life of Plants" became a bestseller in the U.S. by offering an astonishing and heretical thesis. It also states that the image of painting is transmitted by extrasensory perception (ESP) at the Maimonides Medical Center in New York City. It adds that in England, 70 percent of the respondents believe in the possibility of extrasensory perception. It also adds that Charles Tart of the University of California reported that his subjects showed a marked increase in extrasensory perception.

The article discusses the physiology of the giraffe, an animal that ranges from 15-18 feet. Its heart and lungs measures 7-10 feet far below the head. The circulatory system of a giraffe is analyzed through its heart and brain, and found out that its pressure and heartbeat vary in accordance with its activity. Telemetering apparatus is placed in the neck of the animal in order for the observers to record natural variations in blood pressure. The circulatory problems experience by a giraffe is identified.

Focuses on the importance of direct endocranial evidence on the neurological organization of early primates, including hominids and putative homonids, in tracing the evolution of the human brain. Cortical landmarks that distinguish between the pongids and hominids; Period of existence of primates with essentially human brains; Inferential evidence that the emergence of the human brain was paralleled by the initiation of human social behavior.

A source of ideas for automata theory — the study of the brain — has been pushed aside in mathematical development of the theory. This paper suggests the ways in which automata theory might evolve over the next 25 years if it is to contribute to an understanding of how the brain processes information. [ABSTRACT FROM AUTHOR]

Focuses on physiologist Ivan Petrovich Pavlov and his chief discovery of the conditioned reflex. Exemplification of the embryological development of the individual by Pavlov; Statement that Pavlov made his great advances in the physiology of secretion as a result of the ingenious method he used to study secretion in the normal, intact healthy animal; Discussion of Pavlov's contributions to the study of the mental life; Difference between animal automaton and man; View of Pavlov that the physiological, or unconditioned reflex, secretion to be of the same order of phenomena as the psychical, or conditioned reflex; Fact that the fundamental and difficult discovery that a gland can be used as a quantitative index of excitation and inhibition in the brain; Emphasis on the fact that the reflex nature of the mental life depends upon laws, and determinism as a factor in the higher nervous activity; Discussion of the ingenious method of using the salivary gland as a measure of cortical excitation.

Any individual with a really active and vital sense of the function of the mind will find himself in considerable difficulty, even painfully confused, when asked to explain the principal problems man faces and to state, as nearly as possible, what he thinks of the general nature of things. Only those who rigidly adhere to inherited beliefs or those who after a period of investigation have arrested the development of their minds by reducing their beliefs to a fixed system will remain unconfused by such a question. As far as the author is concerned, he has always tried to avoid these easy attitudes, not because of any natural restlessness or taste for change, but because of the significance he attributes to the mind. For him the function of the mind consists in evolving an always more satisfactory and feasible awareness of reality.

The article reports on developments in the study of the human brain. Researchers studied the depths of the human brain by planting electrodes several inches down in the living brain. In his study of the monkey, Jose M. Rodrigues Delgado, a Spanish physiologist, discovered that passing a current through different parts of the cortex will allow him to stimulate a resting monkey to make some actions. Meanwhile, Tulane University researchers wired patients' brain to study schizophrenia.

The article reports on the preparation of surgical teams and medical centers all over the world for the first heart transplant. It notes on the story of two separate cases where the heart of the victim who died instantly having hit by a car and transplanted to the person who had a heart failure. It narrates how the ultimate operation was done and how it ended a success. Moreover, it also acknowledges the success of other transplants performed in other countries as well.

The article focuses on events involving the mass murder in the University of Texas in Austin, Texas by Charles Joseph Whitman in August 1966. It reports that the mass murder, which was done in the observation deck of a limestone tower above the university, left 13 people dead and 31 wounded. It explains that the psychosis of Whitman, who also killed his wife and mother before the murder, can be attributed to the role of his father in shaping his behavior and his relationship with his mother.

The article explores the frontiers of the human brain. Psychologists, biologists, and physicists around the world are poking, prodding and analyzing the organ to unlock its secrets. Understanding the functions of the brain in thought, memory and in consciousness are considered to be the key to come up with better ways of treating the psychoses and neuroses. The scientific effort to fathom the miracle of the brain as it performs a variety of function and keeps man in touch with the world around him is proceeding on many unrelated fronts.

Focuses on the experiments related to nutrition conducted in recent years by researcher Frederick T. Zimmerman, of Columbia University, and his associates, Bessie Bergemeister and Tracy Putnam, at the Neurological Institute in New York City. Information that protein is the most important source of nitrogen, and the body relies mainly on it for energy; Importance of glutamic acid in the human body; Description of a theory which says that glutamic acid has a beneficial effect upon changes in the electrical potential of the brain cells such as take place during nerve activity; Information on the experiments by Bergemeister which show heightened mental activity when massive doses of glutamic acid have been consumed.

The article reports on the possibility for the human brain to visualize four-dimensional structures. According to the 19th-century German physicist, Hermann von Helholtz, it is possible, provided that the brain is given proper input data. However, the experiences gathered are confined to three-space and there is not the slightest scientific evidence that four-space actuallly exists. A diagram on the steps toward generating a hypercube is also presented.

The article presents information on a research regarding the influence of brain to translate the genetic information into the differentiation of the sexes. The research conducted in the newborn rats, by changing the sex organs, revealed that the physiological and behavioral sexual differentiation in mammals cannot be explained only in terms of hormones.

The article discusses the function of the pineal gland which is a small organ near the center of the mammalian brain. Studies indicate that the pineal is a sensitive biological clock converting cyclic nervous activity generated by light in the environment into endocrine information. The evidence at hand suggests that the pineal participates in some way in the regulation of the gonads.

The article discusses the intellectual continuity throughout the evolutionary hierarchy of animals. Animals have been known to be born with tendencies to react in certain ways to certain stimuli. Probability learning experiments were conducted to evaluate responses to stimulus of various animals. Studies of habit reversal and probability learning in the lower animals imply that brain structures in higher animals do not serve merely to replicate old functions and modes of intellectual adjustment but to mediate new ones.

The article discusses the cerebral commissures which connect the two halves of the mammalian brain. The author has explained how each of the hemisphere of the brain functions, featuring corpus callosum and optic chiasm. He has also presented an analysis of its organization and operation on the basis of his split-brain studies. His research aims to provide information on the possible effects of the cutting of the entire corpus callosum, giving details on how each parts of the brain function.

The article studies how the visual cortex of the brain analyzes images via the retina. The transformation of the retinal image into a perception occurs partly in the retina but mostly in the brain. The process begins with the responses of light-sensitive receptor cells in each retina. From these cells messages are transmitted to other retinal cells and then sent on to the brain. Neurons transmit messages in the form of brief electrochemical impulses.

The article discusses on human abilities' mental concentration and perceiving information or speech from any sources. According to the findings, it is difficult to understand two messages at the same time than two messages arriving one at a time, therefore to perceive a message, the other message must be rejected. This indicates that the brain has an attention mechanism for selecting the desired information.

The article provides information on the cause of reversal on figures during prolonged viewing of a person. This aftereffects in one's perception has been correlated with electrochemical changes in the brain. A current is produced by the sensory stimulus through the area of the cerebral cortex to which the stimulus is relayed, fatiguing the current carrying capacity. This process permits the configuration to take over for a while until it appears weak and gives way to the original perceived configuration.

The article analyzes the function of the satellite cells in the nervous system. Charles Sherrington, a British physiologist, described the brain as an enchanted loom. Studies show that a chemical analysis of one milligram of brain tissue can not indicate the composition of neurons and glia separately. It will only give an average value for nervous tissue, without anatomical correlation.

The article discusses the reception of sound through the ears and the function of the brain in auditory localization. Auditory localization may be achieved with more efficiency by having a complete pair of receptors or ears. Giovanni Battista Venturi, an Italian physicist, was the first to conduct studies of this nature. Experiments revealed that each ear is represented more strongly in the opposite side of the brain than in the same side thus, a sound on one ear excites neural activity in the opposite side of that ear.

The article focuses on the ability of the human eye to see straight lines. The eye's actual precision in certain visual observations has been emphasized. The ability of the brain to examine its associated retina has been emphasized. The significance of the functional geometry, a method that generates spatial relations in the course of the normal functioning of the visual system on the eye. The features of the method have been discussed.

The article provides information on the cerebellum,located at the back of the brain, to ascertain its function in the central nervous system. A study was conducted to investigate the matter and it stressed that mapping out the cerebellum's electrical circuits suggests it is perhaps the monitor of communication between brain and body, and the control center for balance and movement coordination.

The article presents information about the evolution of brain. The ability to represent or symbolize an experience in the absence of a stimulus is an important step in mental evolution for it prepares the ability of an animal to understand and think. Learning in infrahuman and even in human is developed through constant training of activities. The future of infrahuman animals lies with nature, mutations and natural selection, while the future of man is under his control.

The article focuses on the discovery of the reticular formation, a tiny nerve network in the central part of the brain stem. This part of the brain is a very essential aspect in underlying human awareness of the world and the ability to think. It awakens the entire brain when a stimulus travels along a pathway. The function of the reticular formation is discovered by psychologists H. W. Magroun and Giuseppe Moruzzi.

The article explains how the building a cocoon by a silkworm was used to investigate the circuitry of the nervous system. The study was conducted at the biological laboratories at Harvard University. Their focus was to get inside the silkworm in order to determine how its central nervous system translates the incoming sensory barrage into an outgoing series of coordinated motor signals.

The article offers information on the new approach in investigating the biochemistry of mental illness, which made use of drugs called chlorpromazine, reserpine, and Frenquel. The author has emphasized how these drugs are going to reduce the cost of caring for the mentally ill and decrease the number of mental patients in hospitals. He has also discussed the effects of the drugs on the brain's chemistry, emphasizing on the consequent changes in the hypothalamus. His discussion on how this development may led to finding other suitable drugs which can act on the neurohormones of the brain to counteract disturbances in the mind concludes the article.
