The insular cortex, also called the insula, lobus insularis or insular lobe, is one of the most mysterious parts of the human brain and is barely larger than a 2 euro piece. Evolutionarily, this part of the human brain is ancient and performs many different tasks, not all of which have been discovered yet. What … Insular Cortex: Structure, Function & Diseases
The sense of smell in humans is also called olfactory perception and is divided into three different anatomical structures with the olfactory epithelium, the olfactory filaments and the upstream part of the olfactory brain, which are jointly responsible for the perception as well as processing of odor stimuli. Although the sense of smell in humans … Sense of Smell: Function, Tasks, Role & Diseases
The limbic system is a functional unit in the area of the brain that is responsible for processing emotions. It consists of several parts of the brain that work closely together. Diseases can cause serious discomfort and should be treated promptly. What is the limbic system? The limbic system includes brain areas that are in … Limbic System: Structure, Function & Diseases
Definition The name hippocampus comes from Latin and means translated seahorse. The hippocampus as one of the most important structures of the human brain bears this name in reference to its seahorse-like form. It is part of the telencephalon and is found once in each half of the brain. Anatomy The name hippocampus comes from … Hippocampus
Diseases of the hippocampus In some people suffering from depression, a decrease in the size (atrophy) of the hippocampus has been observed in studies. The people most affected were those with chronic depression (lasting for many years) or those with very early onset of the disease (in early adulthood). In the context of depression, there … Diseases of the hippocampus | Hippocampus
MRT of the hippocampus Magnetic resonance imaging, also known as MRI, is the imaging diagnosis of choice for assessing possible pathological changes in the brain, including the hippocampal region in the temporal lobe. Within the framework of epilepsy diagnostics, even small lesions or abnormalities can be detected and treated at an early stage. MRI of … MRT of the hippocampus | Hippocampus
The formatio reticularis form a nerve plexus in the human brain that consists of gray as well as white matter (substantia alba and substantia grisea) and traverses the entire brainstem. It extends to the spinal cord and consists of extensive, diffusely connected neuron networks. The formatio reticularis controls, among other things, waking and sleeping states, … Formatio Reticularis: Structure, Function & Diseases
The fornix cerebri is part of the limbic system and forms a curved projection pathway between the mamillary bodies (corpora mamillara) and the hippocampus. The fornix cerebri can be divided into four areas and consists of fibers of the olfactory pathway. It is associated with memory retrieval, which is why damage to the fornix cerebri … Fornix Cerebri: Structure, Function & Diseases
The sense of touch is composed of feedback from several different sensors in the skin, which is linked and evaluated by the brain and is available to us as tactile perception. This can involve a perception of being passively touched or being actively touched. In a broader sense, the sensation of pain and temperature also … Sense of Touch: Function, Tasks, Role & Diseases
The human mesolimbic system is called the positive reward center. It is part of the central nervous system. It is located in the cerebrum of the human organism. What is the mesolimbic system? The mesolimbic system is also known as the area tegmentalis ventralis. It is composed of the nucleus accumbens and parts of the … Mesolimbic System: Structure, Function & Diseases
The term “limbic system” refers to a functional unit localized in the brain that serves primarily to process emotional impulses. In addition, the limbic system controls the development of drive behavior. The processing of essential components of intellectual performance is also attributed to the limbic system. In connection with these complex processes, however, the limbic … Limbic system
Fornix The so-called fornix consists of a pronounced fibrous cord that connects the hippocampus with the mammillary corpus above the third ventricle. As part of the functional circuit known as the “limbic system“, the fornix is also involved in the transfer of information from short-term to long-term memory. Corpus mamillare The corpus mamillare is a … Fornix | Limbic system
