The beginnings of physiology of the human brain, from antiquity to the Renaissance

Abstract

For more than 3,000 years in Western civilizations, the knowledge of the human body gained very little ground at first, due to taboos. The body was regarded as sacred and Medicine only resorted to plants in order to heal. Hippocrates was not familiar with anatomy as the human body could not be dissected. He developed a theory of humors connected with the primary elements and opposing the dry and the moist. Even though he did not know the nervous system, he nonetheless pointed out that emotions stemmed from the brain and were caused ty particles (pneuma) emitted by the objects around us. Galien was one of the first to mention physiology but could only dissect animals to understand Man. He took up the theory of humors but did not reach any concrete results as he considered the brain as made up of faeces. Only in 1000 AD did Avicenne try to shape the cell theory with its three cells (the ventricles in today's parlance) in direct relation to the nerves, which he described but did not represent. Representation of the nerves was only be given in the mid-13th century by Khalifah in his ophtalmology treaty. Finally, during the Renaissance, when books started conveying both text and pictures, brain physiology emerged; Albert le Grand wa...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
