Complex combinations of many reflexes, which we collectively call animal or human attitudes

Humans and higher animals have a number of behaviours and attitudes in response to circumstances that cannot be explained by normal physiological laws.

When people are happy, they eat well; when they are sad, they do not want to eat, even though they are hungry.

In animals like dogs, when it sees a person entering the house, if it is the owner, it wags its tail happily, if it is a stranger, it barks and bites. Thus, the same human shape but the dog has different reflexes. People did an experiment to remove the dog's cerebral cortex, after recovering, it found that the dog's behaviour was different from before, it saw that the owner was not happy, saw strangers not barking, not biting.

The complex combinations of many reflexes, which we collectively call the attitudes of animals or humans, is a problem that is currently being studied by many scientists, but no one has come to a definite conclusion. body.

Pavlov and his colleagues did many experimental studies on the behavioral phenomena of animals which he called higher neurosis, and he formulated the theory of conditioned reflexes. This is a huge contribution to Physiology and Medicine especially to Physiology of the Brain.

Currently, a number of physiological functions such as learning, memory, thinking, speaking, etc., do not have precise terms to describe, so they are temporarily called "high-level functions of the nervous system". Collectively it is the intellectual functions of the brain, which is an infinitely richer, more complex and difficult field of study than any other.

Therefore, to study this problem, it is necessary to have the cooperation and coordination of many other specialities such as biophysics, biochemistry, bioelectricity, morphological sciences, mathematics, cybernetics, psychology, etc. and many other specialities.
