A study of the inner navigation system of the human brain

Some parts, such as the cerebral cortex and the cerebellar cortex, consist of layers that are folded or convoluted to fit within the available space.

These areas receive input from the sensory areas and lower parts of the brain and are involved in the complex cognitive processes of perceptionthoughtand decision-making. Each hemisphere is divided into four main lobes[8] although Terminologia Anatomica and Terminologia Neuroanatomica also include a limbic lobe and treat the insular cortex as a lobe.

The process of forming male reproductive cells, called spermatozoa singular spermatozoonis called spermatogenesis. Another mechanism proposed for DNA damage is related to the leakage of DNAase through the membranes of lysosomes, due to the calcium efflux effect see section on calcium efflux below.

Except for a few primitive organisms such as sponges which have no nervous system [13] and cnidarians which have a nervous system consisting of a diffuse nerve net [13]all living multicellular animals are bilateriansmeaning animals with a bilaterally symmetric body shape that is, left and right sides that are approximate mirror images of each other.

These include the nucleus accumbensnucleus basalisdiagonal band of Brocasubstantia innominataand the medial septal nucleus. Rather, the autonomic nervous system and the communication between the heart and brain were much more complex, and the heart seemed to have its own type of logic and acted independently of the signals sent from the brain.

Fewer bees returned to the hive, and the exposed hives had lower honeycomb weights. Visually, the interior of the brain consists of areas of so-called grey matterwith a dark color, separated by areas of white matterwith a lighter color. From the perspective of biochemistry, ATP is classified as a nucleoside triphosphatewhich indicates that it consists of three components, a nitrogenous base adeninethe sugar ribose, and the triphosphate.

It lies in the back part of the skullresting on the part of the base known as the clivusand ends at the foramen magnuma large opening in the occipital bone.

Researchers discover 'inner compass' in the human brain

The primary function of the basal ganglia appears to be action selection: It is possible that we will see a similar or even shorter time lag between wireless technology use and its long-term consequences. Blackman discovered two power density windows in which calcium would be removed from brain tissue.

Brain damage is a serious problem which can ruin the human life, because the brain is no less important the heart. In eutherian placental mammals, the hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers. Astrocytes are the largest of the glial cells.

Nicknamed the balance hormone, it plays an important role in fluid and electrolyte balance and helps regulate the blood vessels, kidneys, adrenal glands and many regulatory centers in the brain. The remaining parts of the cortex, are called the association areas.

Some students built a Faraday cage around whole areas of forest, and those were the areas where the forests started to regenerate Radiation-induced increase in oxidative and nitrosative free radicals may result in DNA damage as well as hinder the repair process. In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called the pallium.

The brain can thus be described as being divided into left and right cerebral hemispheres. The follicle is now ready to release its oocyte during ovulation.

Removal of the cerebellum does not prevent an animal from doing anything in particular, but it makes actions hesitant and clumsy. It has not been definitively established whether the existence of these brainless species indicates that the earliest bilaterians lacked a brain, or whether their ancestors evolved in a way that led to the disappearance of a previously existing brain structure.

In any case, it is interesting to note that the use of prescription sleep aids has nearly tripled in young adults between and. Feb 12,  · A Description of Human Brain.
