Self generated sounds and the DCN

Let me introduce the protagonist: the DCN

DCN is the abbreviated form of dorsal cochlear nucleus. The DCN is a brainstem nucleus. DCN receives direct auditory input from the cochlea via the auditory nerve. The DCN also receives somatosensory input about the head, ear and jaw. Why do we have multisensory input at the first point at which auditory information is processed in the brain? This recent paper looks into the DCN, a multisensory hub.

We looked at how movement suppresses sensory information earlier. Seems like the DCN is the place where something similar happens in the auditory system.

Nicotine avoidance and GLP-1 neurons

After stuffing your face with < enter favourite food >, you invariably feel full. You simply can’t eat anymore. This satiety is not an aversive experience, but rather an avoidance response.  Apparently, smokers also feel this satiety when it comes to their nicotine intake. They can titrate their nicotine intake to avoid the noxious effects of high levels of nicotine.

How does this come about?

The following paper from Tuesta et al., looks at the circuitry behind the phenomenon.

Practise what you preach

The recent US election brought home once again the reluctance of large swathes of educated population to accept the ‘theory’ of evolution. A mere passing mention of the ceaseless creationist vs evolutionist debate triggers a stereotypical reaction from anyone who considers oneself even remotely related to scientific circles (graduate students, for example): a sigh, an awkward little laugh and apparent willingness to change subject, or – if you are lucky – a feat of righteous wrath and an impromptu lecture on the dire necessity of ‘educating the masses’.

Top 20 alternative career paths

What comes after your PhD ? You might be wrapping up your PhD, set for a post-doc and suddenly having doubts about your career choice. Or, you might be just starting your PhD. It’s never too late, or too early, to give some thought to your career.

You can read about GSN student Sara’s  approach here.

Below is a list of top 20 alternative career paths, compiled by Cheekyscientist (from their free ebook).  Cheekyscientist is a platform that helps PhDs transfer from academia to the industry.

Tips on applying for a PhD

It’s that time of the year again. And no, I am not talking about New Year’s resolutions (although sticking to them will probably be on the top of your list). I am talking about Graduate School Applications. Chances are that if pursuing a Master’s or a PhD has crossed your mind you will already be in the midst of scanning through dozens of Programmes/Scholarships and trying to figure out a way to make your application stand out from the rest. It’s a very busy, stressful and time-consuming period, but also one that will determine the next few years of your life and career. Continue reading “Tips on applying for a PhD”

Interview with Patricia Churchland (part 2): about leaving academia, sexism and letting the brain go wild

I sat down for an interview with Patricia Churchland, the founder of neurophilosophy, before she gave a talk as part of the Munich Neuroscience Lecture Series on December 5th 2016. We talked about various topics including working in interdisciplinary teams, science communication, thinking of leaving research and being a woman in science. In this second part, we discussed leaving academia, sexism and letting the brain go wild. You can find Part 1 of the interview here.

Resources for post-PhD considerations

Yes, it will be that time next year: when I need to figure out what I’m doing with my life. Academia? If not, what options are there? Since I have spent some time looking for other options, I will share the resources I came across – maybe you also need to figure out what to do with your life next year?

How to legally re-use your own figures

When working on the figures for a recent paper I realised that I was using schemes of the animal I work with that come from a copyright-protected book. I decided that I will get rid of those schemes and instead produce my own. However, there was still a potential copyright issue: depending on where the paper would be published, the rights for the figures might well end up with the journal rather than with me. The solution that allows you and others to re-use your own figures is to publish everything on a platform such as figshare under a creative commons license before you publish it in a paper, and then cite yourself on figshare in your paper. That’s what I did! Continue reading “How to legally re-use your own figures”

The single reason why basic research is important

basic research

People like me who are doing basic research are often asked how our basic science research can be applied. Most of the time, we don’t know. Nobody knows. Maybe someday we will, maybe we won’t. This is not important. Why not? Continue reading “The single reason why basic research is important”
