We are recruiting a Research Software Engineer to work between the Sainsbury Wellcome Centre (SWC) Neuroinformatics Unit (NIU) and Advanced Microscopy facilities (AMF) to provide support for the analysis of light microscopy datasets. The AMF provides support for all light microscopy at SWC including both in-vivo functional imaging within research laboratories and histological imaging performed within the facility itself. The facility provides histology and tissue clearing as a service, along with custom-built microscopes (lightsheet and serial-section two-photon) for whole-brain imaging. The NIU (https://neuroinformatics.dev) is a Research Software Engineering team dedicated to the development of high quality, accurate, robust, easy to use and maintainable open-source software for neuroscience and machine learning. We collaborate with researchers and other software engineers to advance research in the two research centres and make new algorithms and tools available to the global community. The NIU leads the development of the BrainGlobe (https://brainglobe.info/) computational neuroanatomy initiative. The aim of this position is to work in both the NIU and AMF to develop data processing and analysis software and advise researchers how best to analyse their data. The postholder will be embedded within both teams to help optimise all steps in the software development process.

Among all prevalent diseases with a central neurodegeneration, AMD can be considered the most promising in terms of prevention and early intervention, due to several factors surrounding the neural geometry of the foveal singularity. • Steep gradients of cell density, deployed in a radially symmetric fashion, can be modeled with a difference of Gaussian curves. • These steep gradients give rise to huge, spatially aligned biologic effects, summarized as the Center of Cone Resilience, Surround of Rod Vulnerability. • Widely used clinical imaging technology provides cellular and subcellular level information. • Data are now available at all timelines: clinical, lifespan, evolutionary • Snapshots are available from tissues (histology, analytic chemistry, gene expression) • A viable biogenesis model exists for drusen, the largest population-level intraocular risk factor for progression. • The biogenesis model shares molecular commonality with atherosclerotic cardiovascular disease, for which there has been decades of public health success. • Animal and cell model systems are emerging to test these ideas.

Epilepsy is one of the most common neurological diseases according to the World Health Organization (WHO) affecting around 70 million people worldwide [WHO]. Patients who suffer from epilepsy also suffer from a variety of neuro-psychiatric co-morbidities, which they can experience as crippling as the seizure condition itself. Adequate organization of cerebral white matter is utterly important for cognitive development. The failure of integration of neurologic function with cognition is reflected in neuro-psychiatric disease, such as autism spectrum disorder (ASD). However, in epilepsy we know little about the importance of white matter abnormalities in epilepsy-associated co-morbidities. Epilepsy surgery is an important therapy strategy in patients where conventional anti-epileptic drug treatment fails . On histology of the resected brain samples, malformations of cortical development (MCD) are common among the epilepsy surgery population, especially focal cortical dysplasia (FCD) and tuberous sclerosis complex (TSC). Both pathologies are associated with constitutive activation of the mTOR pathway. Interestingly, some type of FCD is morphological similar to TSC cortical tubers including the abnormalities of the white matter. Hypomyelination with lack of myelin-producing cells, the oligodendrocytes, within the lesional area is a striking phenomenon. Impairment of the complex myelination process can have a major impact on brain function. In the worst case leading to distorted or interrupted neurotransmissions. It is still unclear whether the observed myelin pathology in epilepsy surgical specimens is primarily related to the underlying malformation process or is just a secondary phenomenon of recurrent epileptic seizures creating a toxic micro-environment which hampers myelin formation. Interestingly, mTORC1 has been implicated as key signal for myelination, thus, promoting the maturation of oligodendrocytes . These results, however, remain controversial. Regardless of the underlying pathophysiologic mechanism, alterations of myelin dynamics, depending on their severity, are known to be linked to various kinds of developmental disorders or neuropsychiatric manifestations.

The standard method for staining structures in the brain is to slice the brain into 2D sections. Each slice is treated using a technique such as in-situ hybridization to examine the spatial expression of a particular molecule at a given developmental timepoint. Depending on the brain structures being studied, slices can be made coronally, sagitally, or at any angle that is thought to be optimal for analysis. However, assimilating the information presented in the 2D slice images to gain quantitiative and informative 3D expression patterns is challenging. Even if expression levels are presented as voxels, to give 3D expression clouds, it can be difficult to compare expression across individuals and analysing such data requires significant expertise and imagination. In this talk, I will describe a new approach to examining histology slices, in which the user defines the brain structure of interest by drawing curves around it on each slice in a set and the depth of tissue from which to sample expression. The sampled 'curves' are then assembled into a 3D surface, which can then be transformed onto a common reference frame for comparative analysis. I will show how other neuroscientists can obtain and use the tool, which is called Stalefish, to analyse their own image data with no (or minimal) changes to their slice preparation workflow.

Von Economo stated that an "Ideal Cortical Map" would look very different to a parcellation. He suggested that an Ideal Cortical Map would involve the superimposition of many different cortical maps, with changes in each map shown at every single point. In line with this idea, I will discuss our recent research on identifying principal dimensions of cortical differentiation. In particular, I will highlight large-scale patterns of cytoarchitectural differentiation that can be observed using post mortem histology or in vivo microstructure-sensitive MRI. I aim to show how this approach provides a cohesive framework to understand cortical organisation across multiple biological scales. This allows us to formulate new ideas on the organisation and function of the brain regions (eg: mesiotemporal lobe), networks (eg: DMN) and the whole cortex.

Join us for a comprehensive introduction to multielectrode recording technologies for in vivo neurophysiology. Whether you are new to the field or have experience with one type of technology, this webinar will provide you with information about a variety of technologies, with a main focus on Neuropixels probes. Dr Kris Schoepfer, US Product Specialist at Scientifica, will provide an overview of multielectrode technologies available to record from one or more brain areas simultaneously, including: DIY multielectrode probes; Tetrodes / Hyperdrives; Silicon probes; Neuropixels. Dr Sylvia Schröder, University of Sussex, will delve deeper into the advantages of Neuropixels, highlighting the value of channel depth and the types of new biological insights that can be explored thanks to the advancements this technology brings. Presenting exciting data from the optic tract and superior colliculus, Sylvia will also discuss how Neuropixels recordings can be combined with optogenetics, and how histology can be used to identify the location of probes.
