The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Neuroestrogens likely contribute to appetite regulation

Although a woman's ovaries produce the most estrogen, various types of estrogen are also synthesized throughout different tissues in the body, including the brain's neurons.

Plant immune responses may offer insights into human brain diseases

A groundbreaking study led by a team of researchers at the University of Kentucky's Martin-Gatton College of Agriculture, Food and Environment has revealed a surprising biochemical connection between plant immune responses and human neurological health.

Study shows promise for new treatment approach for multiple sclerosis

A sponge-like implant in mice helped guide a treatment that slowed or stopped a degenerative condition similar to multiple sclerosis in humans. It also gave University of Michigan researchers a first look at how primary progressive multiple sclerosis, the fastest-progressing version of the disease, attacks the central nervous system early on.

Direct connection found between memory and sensory processing centers in brain

A newly identified part of a brain circuit mixes sensory information, memories, and emotions to tell whether things are familiar or new—and important or just "background noise."

Nerinetide shows promise in stroke treatment meta-analysis

The Calgary Stroke Program, a joint University of Calgary and Alberta Health Services initiative at Foothills Medical Centre, has been involved with three papers published this week in The Lancet and Lancet Neurology-the ESCAPE-NEXT trial, the FRONTIER trial, and an individual patient-level meta-analysis across three trials.

Lower vitamin B12 levels could impact brain function in older adults

Meeting the minimum requirement for vitamin B12, needed to make DNA, red blood cells and nerve tissue, may not actually be enough – particularly if you are older. It may even put you at risk for cognitive impairment.

Cholesterol metabolite linked to Parkinson's disease development in mice

Researchers led by Zhentao Zhang at Wuhan University, China have discovered a cholesterol metabolite that plays a critical role in the development of Parkinson's disease in mice.

JAX researchers identify key genetic factors influencing eye aging in mice

Vision changes are an inevitable part of aging, but why are some more susceptible to age-related eye diseases and why do some individuals experience more severe decline than others?

New drug mimics low-oxygen treatment for Leigh Syndrome

For the average person, living at high altitude-where oxygen is sparser than at sea level-can have health benefits ranging from lower rates of heart disease to increased endurance.

Researchers identify MLC1 as potential target in multiple sclerosis

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system caused by the immune system. B cells, which are a type of white blood cell, play a role in the development of MS and are thus a target for therapies.

New review maps the impact of reproductive hormones on neurological health

A comprehensive review published today in Brain Medicine by leading neuroendocrinologist Professor Hyman M. Schipper from McGill University's Department of Neurology and Neurosurgery maps out the extensive influence of reproductive hormones on neurological health and disease.

Human-specific gene variant may hold key to evolution of language

The origins of human language remain mysterious. Are we the only animals truly capable of complex speech? Are Homo sapiens the only hominids who could give detailed directions to a far-off freshwater source or describe the nuanced purples and reds of a dramatic sunset?
