Hippocampus (sea horse or hippocampus) is located deep in the temporal lobes and is elongated elevation (for and hydrochloric 3 cm) on the medial wall of the lower, or temporal, horns of the lateral ventricle. This elevation, or protrusion, is formed due to deep indentation from the outside into the cavity of the lower horn of the hippocampal groove. Hippo about Kamp considered as the basic structure and how arhiokorteksa amounted in hydrochloric portion olfactory cortex. In addition, the hippocampus is the main structure of the limbic system, it is associated with many structures mo of hectares, including through commissural connections (fornicommissure) – with HIPD about Kamp opposite side, although a person found objectified th Lena independence in the activities of both hippocampi. Neurons HIPD about Kampa expressed different background activity, and bolshins tons in one characterized polytouch, t. e. Reacts on the Vat on the light, sound and other stimuli. Morphologically hippocampus is presented stereotypically repetitive modules Neira of newly connected among themselves and with other entities. The connection of the modules creates the condition for the circulation of electrical activity in the hipp about the camp during training. This increases the amplitude of the synaptic n of potentials are increased neurosecretion and hippocampal cell number m and peaks on its dendrites of neurons, indicating that the transition sweat n socially active synapses. The modular structure makes the joint venture on lities hippocampus to generate high-amplitude rhythmic and to tivnost. Background electrical activity of the hippocampus has been shown in humans, it is characterized by the rhythms of two types: fast (15 – 30 cycles per second) low voltage type beta rhythm and tarry n GOVERNMENTAL (4 – 7 vibrations per second) high-voltage type theta rhythm. In this case, the electrical rhythm of the hippocampus is in reciprocal rel about sheniyah with the rhythm of the neocortex. For example, if a new theta rhythm is recorded during sleep, a beta rhythm is generated in the hippocampus during the same period, and the opposite picture is observed in the new bark — the alpha rhythm and beta rhythm in the new cortex, and in the hippocampus theta rhythm. It has been shown that activation of neurons reticulo p hydrochloric formation brainstem enhances expression of the theta rhythm in the GIPP about kampa and beta rhythm in new bark. A similar effect (an increase in theta rhythm in the hippocampus) is observed during the formation of a high level of emotional tension (with fear, aggression, hunger, thirst). Reader and etsya that hippocampal theta rhythm reflects its participation in orienting reflex in nastorazhivanie reactions, improve attention, learning dynamics. In this regard, the hippocampal theta rhythm is regarded as an elective to troencephalographic correlate of the awakening response and as a component of the orienting reflex.
The role of the hippocampus in the regulation of vegetative functions and the endocrine system is important. It is shown that especially hippocampal neurons during its excitation can have a pronounced effect on the cardiovascular activity by modulating the activity of the sympathetic and the steam and the sympathetic nervous system. The hippocampus, as well as other structures and p hiopaleokorteksa involved in the regulation of endocrine B activity with the theme, including the regulation of the release of glucocorticoids and thyroid hormones, which is realized with the participation of the hypothalamus. Gray in e sches tonnes in the hippocampus belongs to the motor area of the olfactory cortex. It is from there downward impulses to subcortical Motor and tion centers, causing movement in response to certain olfactory I -inflammatory stimuli.
