In press at last!

16 10 2019

Lindsey’s social learning paper got accepted at last, after not one, not two, but THREE rounds of revision. One referee was like a dog with a bone, though I have to admit the paper’s better as a result.

New theses in the Atrium!

Congratulations to Sam, and also to Aimee who defended last week too (write-up still to come but teaching’s obliterating everything right now): the final theses of both of them are now online!

Affect-modulated startle in hens!

20 08 2019

Misha’s first hen paper came out this week! In this work we assessed whether improved welfare would reduce chickens’ startle magnitudes (check: the first evidence for affective modulation of this reflex in birds!), and also make their judgment biases more optimistic (kind of … but only if you squint and look at a subset of birds). We then looked to see whether these two forms of stimulus appraisal covary (nope).

It’s lovely, lovely work, produced after a painfully long parturition (tough – if not unreasonable – stats requests from our referees, who also showed alarming convictions that any test you label ‘judgment bias’ is automatically a window into an animal’s very soul).

Mink brain paper in press at last!

6 08 2019

So exciting to see this paper now in the ‘in press’ section of Behavioural Brain Research!

We successfully found individual correlates of stereotypic behaviour (in the nucleus accumbens), but they differed for different sub-types, and also were not affected by housing even though this was massively impactful on behaviour (and despite some independent evidence that housing altered direct:indirect pathway activity). Morals: stereotypic behaviours really are heterogeneous; and the neurological correlates of individual variation may tell you nothing at all about how barren housing causes this behaviour (something that remains a mystery in these animals).

Standard lab cages make female mice aggressive

17 07 2019

Emma N’s paper is out already! Here is a link giving free full access for 45 days or so.

And the short answer to the question in the title is that we don’t know: we just couldn’t fully identify why enriched mice are so much more pacific than standard-caged females. Some of it was that crowding elevates encounter rates, but that wasn’t the full explanation. We suspect frustration and negative judgment biases, but that’s for future work… Meanwhile, just know that female mice sharing good environments are like the Golden Girls; but for those in standard cages, it’s all a bit more Orange is the New Black.

Nice find from Andrea, who’s busy collecting a second batch of monkey data, this time in Portland: our play paper‘s finally doing well!
