detection d' is generally overestimated, coz we tend to be too lazy to collect the necessary data in order to correct for the unequal variance between target present vs absent distributions. turns out we can do this for free - using reaction times data. so, let's do it~

Last year a study of >2.4 million kids born in Sweden looked at Tylenol exposure and autism

At first, it seemed like there was a small association.

But then they compared siblings where one was exposed in utero and the other wasn’t and found no increased risk jamanetwork.com/journals/jam...

Acetaminophen Use During Pregnancy and Children’s Risk of Autism, ADHD, and Intellectual Disability

This nationwide cohort study with sibling control analysis examines the association of acetaminophen use during pregnancy with children’s risk of autism, ADHD, and intellectual disability.

too many people only ask one question when they see the impact of disinformation

(how do we stop this disinformation)

when you should really ask a second

(how do we stop the sentiment that made these people seek out disinformation and accept it uncritically)

Ever thought that food tastes bland when you have a cold? In this piece, I explain how that happens as I summarise my latest article on the neural encoding of odours in the canonical taste cortex!

theconversation.com/smell-trigge...

Smell triggers the same brain response as taste does – even if you haven’t eaten anything

Our latest study showed that taste and smell were both found to activate a region of the brain important for taste, hunger and thirst.

Thank you, Ian!

Our findings highlight the insula's crucial role in flavour integration, explaining why smells are so vital to our perception of taste. So next time you enjoy a meal, appreciate the complex interplay happening in your brain! 🧠🍽️ #Neuroskyence #FlavourPerception 10/10

This implies that the insula encodes a property that doesn't change throughout the session, such as identity. Meanwhile, the convergence in the OFC suggests that it likely encodes something that dynamically changes throughout the session, e.g. subjective value. 9/10

In fact, we developed a method to examine runwise representational drift of flavours in the insula, and we saw a slight divergence between similar and different flavours in the insula over the course of a session, but we could see the opposite effect in the OFC. 8/10

Putu Agus Khorisantono @agustation.bsky.social · 27d

We're the first to show this direct shared encoding between retronasal odours and tastes in humans at the neural level, challenging the current consensus that this integration only happens further downstream in the OFC. 7/10

Why does this matter? Imagine reducing sugar or salt in foods without sacrificing flavour! If certain aromas can trick your brain into perceiving sweetness or savouriness, we could design healthier foods that still taste great. #HealthInnovation 6/10

This integration isn't just anywhere in the insula. We pinpointed it to specific subregions – the dysgranular and agranular anterior insula. Meanwhile, only tastes could be decoded from the activation patterns in the granular subregion. 5/10

Putu Agus Khorisantono @agustation.bsky.social · 27d

What was most interesting, however was that a decoder trained on the tastes and tested on the odours (and vice versa) also performed significantly above chance. This showed that that retronasal odours (aromas) elicit similar activations to their associated tastes in the insula. 4/10

Putu Agus Khorisantono @agustation.bsky.social · 27d

We then used mass-univariate GLM to identify a taste activation map. Within this map, a decoder was able to separate the sweet and savoury tastes. Interestingly, it could also separate 'sweet' and 'savoury' odours. 3/10

Putu Agus Khorisantono @agustation.bsky.social · 27d

We first familiarised participants with sweet & savoury flavours (taste + aroma). They then attended two fMRI sessions where they received just the taste (without smell) or just the smell (without taste). 2/10

Good read on the need for us to integrate fMRI research with other fields of neuroscience. Now to look at how I can do it in my own work... 🤔

The Transmitter @thetransmitter.bsky.social · Apr 8

Until recently, in-vivo brain imaging has largely been absent from… integrative efforts, limiting the opportunities to contribute our discoveries, theories or vision toward a comprehensive view of brain function, writes @avramholmes.bsky.social.

fMRI must break out of its silo

We need to develop research programs that link phenomena across levels, from genes and molecules to cells, circuits, networks and behavior.
