1:26 PM | Adolescence as a risk factor for depression in autism
It has been said that you can’t understand a mind except in the context of the world it lives in. Often an inability to shift your frame of reference may […]

10:05 AM | International Neuroscience Doctoral Programme (INDP) at the Champalimaud Foundation in Lisbon – Portugal
Applications from independent thinkers with curiosity, creativity and drive are sought to join the Champalimaud Foundation’s International Neuroscience Doctoral Programme (INDP). The INDP aims to provide students of diverse backgrounds with a foundation to perform innovative and interdisciplinary work in basic or applied neuroscience at an international level. The Programme is hosted at the Champalimaud […]

1:07 PM | The Neurodiversity Movement: Reconciling Different Perspectives
I have been surprised at the attention received by my last blog. I was bedridden with post-flu vertigo while writing the same. The inordinate time that I had to write […]

1:17 PM | In Development this week (Vol. 142, Issue 2)
Here are the highlights from the new issue of Development:   The ‘second brain’: taking gut development up a Notch The vertebrate gastro-intestinal (GI) tract consists of a regionalized epithelial tube surrounded by mesenchyme that later differentiates into smooth muscle. During the early stages of stomach patterning in chick embryos, the primitive GI track is […]

4:02 PM | Life’s Blueprint website
Dear Colleagues, I recently published a popular book presenting the concepts of embryonic development (Life’s Blueprint: The science and art of embryo creation) at Yale University Press. In addition to the text, I tried to convey the concepts of embryonic development by presenting pairs of images, where one portrays a biological example and the other […]

1:27 PM | The Neurodiversity Movement: Lack of Trust
In the midst of a not-so rationalist society the learned elite of autistic individuals, the few, have launched a reformation movement that has been conveyed primarily through autobiographical accounts and […]

1:20 PM | The rabbit blastocyst modelling (for) vertebrate gastrulation
Form and function of animal gastrulation have been longstanding classics accompanying the rise of experimental embryology, and – as if to square the circle in the literal sense – the blastopore of Haeckel’s original ‘gastrea’ stage[1] was soon (and still is) considered analogous to the straight primitive streak of birds and mammals[2-4]. Both forms are […]

5:59 PM | Of Mice and Milk, Mind and Memory
Among animal models, C. elegansand Drosophila melanogaster are the heavyweight champions in this domain, but when it comes to lactation, as non-mammals they are of limited use. Enter the lab rat, or mouse in this case. Mice allow researchers to systematically investigate mechanistic pathways through which mother’s milk influences offspring neurobiology, immune function, and behavior. Liu and colleagues (2013) investigated these in concert with the precision and dedication of a […]
