Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.

New study links circadian gene variants to winter depression

Variants of the PER3 gene disrupt adrenal adaptation to winter light, leading to serotonin disruption and depression-like behaviors in humanized mice models.

Barrow researchers display Andrea Vesalius' anatomical manikins for the first time

For the first time, researchers at Phoenix's Barrow Neurological Institute have collected and displayed together the "manikins" published nearly 500 years ago by the 16th Century anatomist Andrea Vesalius – works that laid the foundation for modern surgical and neurosurgical training.

Carbonic anhydrase inhibitors clear tau build-up in zebrafish models of tauopathies

A drug commonly used to treat glaucoma has been shown in zebrafish and mice to protect against the build-up in the brain of the protein tau, which causes various forms of dementia and is implicated in Alzheimer’s disease.

New imaging method could transform gene expression research

They say a picture is worth a thousand words. A new method, developed by University of Michigan researchers, creates images that are worth many gigabytes of data, which could revolutionize the way biologists study gene expression. Seq-Scope, developed by Jun Hee Lee, Ph.D., Hyun Min Kang, Ph.D., and their colleagues, was first described in Cell in 2021 as the first method to analyze gene expression at sub micrometer-scale spatial resolution.
