Rethinking the genetic architecture of schizophrenia. - I wrote this with David Porteous in 2011. Apart from an over-emphasis on single rare mutations of large effect (less common for SCZ than for ASD), I think it holds up pretty well ncbi.nlm.nih.gov/pubmed/20380786

very excited to share this new preprint from me and Nick Cheney 😀🧵 arxiv.org/abs/2407.15908-
In which we consider how best to conceptualise the role of the genome in specifying the form of the organism. In other words, how it is that cats have kittens and dogs have puppies.
Clearly, the form of the organism that emerges depends on the genetic material in the fertilised egg (see Dolly, below), but how should we think about this relationship?
Really excited to have this new preprint out 😊, with @HenryDPotter: 𝗕𝗲𝘆𝗼𝗻𝗱 𝗺𝗲𝗰𝗵𝗮𝗻𝗶𝘀𝗺 – 𝗲𝘅𝘁𝗲𝗻𝗱𝗶𝗻𝗴 𝗼𝘂𝗿 𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝘀 𝗼𝗳 𝗰𝗮𝘂𝘀𝗮𝘁𝗶𝗼𝗻 𝗶𝗻 𝗻𝗲𝘂𝗿𝗼𝘀𝗰𝗶𝗲𝗻𝗰𝗲 osf.io/preprints/psya…
In neuroscience, our search for the causes of behavior is often just = a search for the underlying neural mechanisms. Especially when we can use tools like optogenetics to show some activity is "necessary and sufficient" for that behavior to occur
This relies (sometimes explicitly but more often implicitly) on a 'driving' metaphor - both of neural inputs driving activation and of neural activity driving behavior
Autism: The Truth is (not) Out There - I wrote this ten years ago and it is, depressingly, as relevant as ever...wiringthebrain.com/2014/10/autism…
The evidence that autism has genetic origins is overwhelming. But we don't do a good job of communicating that. And that void is readily filled with pseudoscience...
The genetics of autism is genuinely complex - involving both genetic heterogeneity (of rare mutations) and a polygenic background of common variants. pubmed.ncbi.nlm.nih.gov/35654974/
I often get asked where I would draw the line of which kinds of creatures have "agency" or "free will"
I tend to only speak of "free will" in relation to humans, put purely because of the historical baggage that comes with the term. "Agency" I see as co-extensive with life...
Though some creatures have more agency than others, or maybe different kinds that vary along several dimensions. (Like behavioral flexibility, ability to cope with novel situations, time horizons of control, etc)
A lot of people ask me about my daily routine for neuro-optimising well-being and productivity*
*Narrator: no had in fact asked…
So here goes:
I wake up at stupid o’clock and curse the darkness of the Irish winter. Will I be getting direct sunlight in my eyes this morning? I will in me hole. We won’t see the sun again till February.
I grope my way to the bathroom for a hot shower. Yes, hot. Because it’s 2023 and we’re not fucking cavemen.
One motivator for arguing against free will seems to be the problem of moral luck and its undermining of moral responsibility. 1/n
The idea being that people's behavior is really determined by past events, including their genetic make-up, upbringing, social circumstances, and accumulated experiences... 2/n
...so how could it be right to blame or punish them for doing acts we call "crimes" when all these antecedent causes were really the determinants of their actions? 3/n
