The brain is responsible for our experience of, and acts as the interface between, the self and the outside world. Everything we think, feel, remember and dream is written by a precisely-interconnected community of approximately 100 billion brain cells. Have you ever wondered where the different types of neurons in our brain originate from? Or how these brain cells then find their way to connect with other cells, up to a metre away in our body? These answers can be found in the developing brain, which arises from the microscopic, but miraculous, embryo.
Creation of our brain
Very early in human development, the embryo consists simply of three fundamental cell layers: outer ectoderm (becomes outer-body parts e.g. skin/hair/teeth); middle mesoderm (develops into muscles, bones and blood vessels); and inner endoderm (forms our inner-body compartments e.g. gut/lungs). That’s most of our body covered, but where does our brain come from? Continue reading “Getting connected with our brain”

The United States Census Bureau says that although women make up nearly half of the working population, they remain underrepresented in science, technology, engineering and maths (STEM) occupations. In the UK, the Women in the STEM workforce (WISE) campaign strives to achieve gender balance in the sector. Recent figures from WISE (Nov 2016) show that while there have been some increases, women still only make up 21% of the Core STEM workforce in the UK. Globally, women make up an average of 28.4% of those employed in scientific research and development according to a recent report. There is a need to encourage and support women in STEM, and the Biochemical Society and Portland Press actively supports female members of the life science community in their goals.
