of the highest departments of a brain was shown
I.M.Setchenov (1863)

in the book "Brain reflexes.
At the beginning of the XX century thanks to works of Nominative of Pavlov there was a radical revolution in studying of function of a cerebral cortex. The doctrine about higher nervous activity, as to a basis of behavior of the person is framed.
It showed that all reflex reactions can be parted on two groups: instinctive and conditioned reflexes.

Слайд 32Studying conditioned reflexes, Nominative Pavlov came to a conclusion that

all activity of a brain is under construction of two

processes:
- exaltations;
- inhibitions.
Rasprostreniye exaltations can provide the generalized reactions covering a series of organs and systems.
Concentration of process can provide narrowing of reflex reaction, its focus.
Inhibition can be generalized and concentrated.
There are some types of cortical inhibition during which exercise conditioned reflexes are oppressed.

Слайд 34
The first type of external inhibition arises right after giving

a postorenny stimulus, i.e. doesn't demand development.
In some cases

it can be characterized as approximate reaction.
There is a reflex: "what the such? " Previous reflex activity thus stops.
The first type of external inhibition arises right after giving a postorenny stimulus, i.e. doesn't demand development.

External inhibition

Слайд 36The second type of unconditional inhibition received the name -

"ULTRABOUNDARY INHIBITION".
It arises at excessive augmentation of force and

duration of action of a conditional stimulus.
I.e. force of a stimulus exceeds operability of cortical cells.
This inhibition has protective value.
The second type of unconditional inhibition received the name -

Слайд 38Internal inhibition

Internal (conditional) inhibition demands special development. The biological sense

of internal inhibition consists that new environmental conditions demand change

There are four types of internal (conditional) cortical inhibition:ugasatelnydifferentsirovochnythe late conditional brake.

Слайд 40Ugasatelnoye - inhibition develops if not to support the developed

reflex with an unconditional stimulus.
Thus the conditional stimulus loses

value of a signal and reaction to it is slowed down, but the conditioned reflex doesn't disappear and can be restored if again to support it with an unconditional stimulus.
Ugasatelnoye - inhibition develops if not to support the developed reflex with an unconditional stimulus. Thus the

Слайд 53Nominative Pavlov, studying development and fixing of conditioned reflexes at

dogs, I defined that an important role in formation like

nervous activity is played by properties of cortical processes: FORCE, STEADINESS, MOBILITY.
Force is degree of expression of processes of exaltation and inhibition.
Steadiness – a ratio of processes of exaltation and inhibition in total amount of biological reactions.
Mobility – rate of emergence and speed of change of processes of exaltation and inhibition.
Taking into account these properties of Nominative Pavlov allocated four VND types.

The theory neural

models - the Physical point of view. Neural models represent as group of nervous cages, communications their steady in time information on memory bear electronic signals. When these signals repeatedly approach to the same synapses, change their electric and mechanical characteristic that facilitates formation of conditioned reflexes. Nervous electronic impulses being grouped in time and space form dynamic neural models.

Слайд 903 . Associative - psychological (will be coordinated with the

theory of neural models). Remembered events, concepts are connected so

that "revival" of one conducts to "revival" of others. This theory says that memoirs are reproduced in the same sequence in which they arose for the first time. It is connected with the theory of neural models (those neurons which are more closely to each other located are quicker raised, activated, is closer on arising representations). Associations are very important at reminiscence.

Слайд 112Stages of emotions or tension degree according to G.I.Kositskomu
CH-I (condition

of tension) - reflects a condition of attention, mobilization of

activity, working capacity increase. It is very useful to an organism.
CH-II (sthenic negative emotion) - is characterized maximum increase in energy resources of an organism and limit tension of bodies and systems (anger, indignation)

Слайд 113CH-III (asthenic negative emotion) - is characterized by exhaustion of

energy resources of an organism (horror, melancholy, decrease in intelligence,

a panic …)
CH-IV (neurosis) - represents a disease, VND failure, "breakage" of a number of regulatory mechanisms of an organism

Слайд 114Motivations are the emotionally painted aspirations of the person and

animals to satisfaction of leading requirements.

Motivations leads to purposeful search

behavior.

Interests – emotional manifestation of informative need of the person.

Types of motivations:

Dominating motivation - the dominating requirement connected

with a condition of an organism at present, evolved internal

requirement. (What to do? )
The starting afferentation – is caused by direct action of an irritant. (When to do? )
Obstanovochny afferentation – caused by action of a certain situation. (It is possible to do? )

Слайд 125 Thus the behavioural act is caused not only incentive, irritation

as it was approved by the classical reflex theory, and

and other components, from them the most important role is played by dominating motivation. In the absence of motivation there is no behavioural act, the organism doesn't react to incentive.
The behavior has to be motivated.
Thus the behavioural act is caused not only incentive, irritation as it was approved by the classical

Слайд 126 In the solution of a question how to make action

a significant role play memory mechanisms.
First of

all, it is genetic memory to which congenital biological motivations are constantly addressed. Isn't less significant and individually acquired memory.
Thus at a stage the EXPERT the issues "what to do" (on the basis of external and internal irritations), "when to do" (on the basis of special starting factors) are resolved.
