Neurosponges for the brain

How does a neural “sponge” work?

There are structures in the brain called the "stria" or "strips". This is a collection of layers of different nerve cells, including glutamatergic, GABAergic and other neurons. They are located parallel to each other, one above the other. This is most noticeable in midline brain structures such as the parietal lobe. In addition, such stripes are located in a number of subcortical nuclei, including the medial strip of the globus pallidus and the anterior pons. It is believed that the main role of the stripe or stripes is coordination of movements, regulation of balance in the equilibrium of the body. There, coordination of movement programs of various limbs is carried out, and kinesthetic feedback is also formed, which helps in muscle coordination.

In addition, there are adhesions of the brain stripes, the so-called “cracks”. Brain pathways pass through interstrip systems. Similar to our consciousness or intuition as an elementary product of the interaction of mental states of different parts of the brain, functions are also carried out by interband connections that ensure interaction between neurons of certain zones of the cortex and subcortex. These are zones that carry out feedback connections, which include associative zones of the cortex and, possibly, interstitial systems or areas of the ancient and new cortex of the cerebral hemispheres that encircle these zones.

We know little about the physiological significance of many “cracks,” but there is reason to suspect them of some special role in the distribution of brain functions and its regulation. Moreover, you need to understand: areas of the brain, primarily the limbic system, are interconnected in almost all spatial and temporal areas. These connections may include conventional neuronal excitatory circuits, inhibitory cells, intermediate modulatory factors such as conduction ion channels, and transmitter substances. It should be noted that depending on the state of the limbic system itself, for example its activity, the activity of all other brain systems changes. It is well known that there are a number of factors in the activity of the limbic brain that determine many mental states of an individual.

Quite often, neurologists - especially for patients with organic pathology of the nervous system hospitalized in institute departments - consider the possible deficiency of various medications that cause the phenomenon of amnesia and incontinence of amnestic activity (or the phenomenon of microaphasia) as a sometimes difficult to differentiate pathology. However, memory impairments, manifested in forgetting one’s own actions in this case, cannot be explained by pharmacological discirculation of the functions of higher nervous activity alone. It is possible that pharmacological agents that create metabolic and electrolyte imbalances disrupt the established rhythm of the fibers and synaptic apparatus of the brain, but the formation of behavioral forms of strong mnestic traces is subject to other, still unknown patterns of the functioning of nerve connections.

It is quite obvious that the microcephalic brain is not wide enough for its volume. Otherwise, the brain will poorly adapt to the local laws of the structure of the system of “functional connections” and internal molecular processes, primarily to obtaining new information about any object. The geometry of the brain has its own laws - just like music
