A neuroscientific approach to reach gender equity

Abstract: Despite the increasing acceptance of egalitarian gender norms in democratic societies, a striking contrast persists in the current societal reality. One of the main reasons gender inequalities persist is the perpetuation of implicit biases and gender stereotypes. These shape the way we behave, our ability to recognize unequal treatment and the willingness of disadvantaged individuals to speak up. The neuroscience community is at the forefront of not only raising awareness of these unconscious biases, but also has the tools to understand their cognitive origins and thus the potential to break down social stereotypes.

Introduction about her journey in Neuroscience as a woman

Imaging synapses in Alzheimer’s disease and related dementias

Synapse loss correlates strongly with the progression of symptoms in Alzheimer’s disease (AD) and other forms of dementia, but mechanisms of synapse loss remain poorly understood.  Our group has observed the accumulation of pathological proteins amyloid beta, tau, and alpha synuclein within individual synapses in neurodegenerative diseases. Further, we find evidence of trans-synaptic spread of pathological proteins from pre to post synapses which contributes to the spread of pathology and neurodegeneration through the brain.  We also observe that astrocytes and microglia are important in synapse degeneration. Understanding synapse degeneration and the spread of pathological proteins through synapses will be important for developing disease modifying therapeutics for Alzheimer’s disease and other neurodegenerative disorders.


Tara Spires-Jones’ research focuses on the mechanisms and reversibility of neurodegeneration in Alzheimer’s disease, other degenerative brain diseases, and ageing.   With a vibrant team of researchers, her work has shown that soluble forms of the pathological proteins amyloid beta and tau contribute to synapse and neurodegeneration, and that lowering levels of these proteins can ameliorate phenotypes in model systems. Her group has also discovered that pathological forms of tau spread through the brain via synaptic connections. Further, she has pioneered high-resolution imaging techniques in human post-mortem brain and found evidence that pathological proteins accumulate in synapses in human disease.

In addition to research, Prof Spires-Jones is passionate about communicating scientific findings to the public and policy makers; increasing the rigour and reproducibility in translational neuroscience; promoting inclusivity and diversity in science; and supporting career development of neuroscientists.  She is President of the British Neuroscience Association (2023-2025).
