The embryonic period is the second period of prenatal development, which lasts from the end of the 2nd week to the end of the 2nd month (counting from the moment of conception). All the main structures and organs of the individual are formed during this period.
Emergent - non-additive characteristic of the system as a whole.
Emotional lability - a quick change of mood for a minor reason.
Emotion is a special class of mental processes and states, reflecting in the form of direct subjective experiences (joy, anger, fear) the importance of phenomena and situations acting on an individual.
Empirical - based on experience.
An engram is a mark left in the brain by an event (in particular, when learning).
Endemic - local, typical of the area.
End (t) o ... is the first component of a complex word, corresponding in meaning to the word "internal", for example: endogenous, endoderm, endoderm.
Endogenous - internal origin, caused by internal causes.
The endogenous component of VP is associated with the activity of the modulating systems of the brain and reflects the subjective assessment of external influence.
Endocrine glands - endocrine glands , that is, not having excretory streams and separating the secretions they produce (hormones) directly into the blood and lymph. The endocrine glands include the pituitary and epiphysis, the thyroid and parathyroid glands, the thymus, or goitre, the gland (thymus), the adrenal glands, and the intrasecretory portions of the pancreas and the sex glands.
Endorphins are neuromodulators that alleviate physical pain. Endorphins play a significant role in relieving stress.
Enigmatic - mysterious, incomprehensible.
Enkephalins - substances produced by the brain to reduce pain; Three types of receptors have been identified in the brain that are activated by enkephalins.
Entoderm - the inner layer of the embryo of multicellular animals and humans in the early stages of its development (inner embryonic leaflet); the endoderm forms the intestinal tract and its associated glands.
Encephalography is a method of radiographic examination of the brain.
Ependyma - a thin membrane lining the ventricles of the brain and the central canal of the spinal cord.
Epi ... is the first part of compound words, denoting the location on top of or near something (eg, epidermis, epithelium), following something (eg, epigenesis).
Epigenesis - the idea of the embryonic development of the organism as a process, carried out by successive transformations.
Epigenetic - formed as a result of any subsequent (secondary) processes.
Epiphenomenolism is a teaching that considers the psyche, consciousness as a phenomenon accompanying physiological processes, a kind of superstructure above them.
Epiphysis - 1) upper brain appendage, or pineal gland; refers to the endocrine glands; 2) cartilage center of growth at the end of each bone.
Ergasia is a concept for the designation of coordinated and purposeful activity of all somatic and mental functions in the norm.
Ergography is a method for graphically recording the work of a person’s muscles.
Estesiometer - a device for measuring the thresholds of sensitivity.
Estrogens - substances with the action of female sex hormones and close to them in chemical composition.
Etiology is a branch of medicine that studies the causes and conditions for the occurrence of diseases.
Ethology - the science of animal behavior, engaged in the analysis of genetically determined components of behavior and the problems of its evolution.
Effector - specialized organs or tissues that react to impulses coming to them from the higher parts of the central nervous system and perform their functions under the action of these impulses.
The efferent part of the reflex is the final part of the reflex arc, which provides the conduction of arousal from the central nervous system to the executive organ (muscle or gland).
Efferent fibers are nerve fibers that conduct impulses from the central nervous system to the muscles and internal organs.
Efferent pathways are nerve fibers that conduct impulses from the higher parts of the brain to the muscles and internal organs.
Efferent synthesis is the stage of the functional system, which comes after the decision-making stage and ends with the action; represents the result of the integration of excitation of the central nervous system and peripheral organs, consists of an action program and control efferent excitation transmitted to the executive organs (muscles, glands).
Juvenile - immature.
Iatrogeny is a disease that occurs as a reaction to words that have been misinterpreted by a patient or a doctor’s behavior, to read medical literature, to messages from friends or the media.
Parallelism - a methodological position that negates the interaction of mind and brain
Ambient afferentation - environmental information
Cortico-limbic interaction = cortico - see the cerebral cortex; limbic - see the limbic system
Sleep stages - slow and fast sleep = fast sleep - see paradoxical sleep
The neocortex is a new area of the cortex that is only identified in lower mammals, and in humans constitutes the bulk of the cortex.
Feminization - the development of the male female secondary female traits
Direction-sensitive cells - neurons-detectors that respond to the movement of the stimulus in a certain direction and with a certain speed
Cranked bodies of the thalamus - subcortical centers of the visual system
The memory vector is a unit of the structural memory code created by a set of postsynaptic contacts on the body of a neuron detector with different electrical conductivities.
