About the Project
The host laboratories have started to phenotype the neurones in the caudal brainstem, an important brain region that serves as a first relay station for peripherally generated signals entering the brain (4,5). Published (2,4) and unpublished data suggest that segregated brainstem circuits selectively respond to distinct nutritional and non-nutritional signals and transmit this information to multiple second order brain regions so that the brain can compute and attribute motivational valence. The overarching aim of this project is to resolve these circuits and characterise them at the genetic, structural and functional level.
To this end, the student will receive training in using the latest genetic technologies available that will allow him/her to genetically tag distinct brainstem neurons after they have responded to the nutritional and non-nutritional signals. This permanent genetic tagging will then allow the student to identify the neurons and their connections, record their activity during normal behaviour and selectively activate/inhibit them to interrogate their significance to behaviour.
Resolving these circuits will not only expand our understanding of how ingestive behaviour is regulated, but it will also inform design of novel medications with improved efficacy and patient compliance.
Applicants must have obtained, or be about to obtain, at least an upper second class honours degree (or equivalent) in a relevant subject.
UK applicants interested in this project should make direct contact with the Principal Supervisor to arrange to discuss the project further as soon as possible. International applicants (including EU nationals) must ensure they meet the academic eligibility criteria (including English Language) as outlined before contacting potential supervisors to express an interest in their project. Eligibility can be checked via the University Country Specific information page (https://www.manchester.ac.uk/study/international/country-specific-information/).
If your country is not listed you must contact the Doctoral Academy Admissions Team providing a detailed CV (to include academic qualifications – stating degree classification(s) and dates awarded) and relevant transcripts.
Following the review of your qualifications and with support from potential supervisor(s), you will be informed whether you can submit a formal online application.
To be considered for this project you MUST submit a formal online application form - full details on how to apply can be found on the BBSRC DTP website http://www.manchester.ac.uk/bbsrcdtpstudentships
