ADHD brains struggle with working memory load.

Nesting tasks three clicks deep creates cognitive friction.

You forget the steps before you even start.

Flat, visible systems reduce this barrier.

Struggling with invisible deadlines? Stop relying on mental schedules.

Under stress, the mind drops time-related tasks.

Draw a physical timeline. Make the abstract sequence concrete.

🧠 New preprint by Zhong et al. proposes a #synaptic mechanism for #chunking in #WorkingMemory.

Using short-term #plasticity and synaptic augmentation, their model shows how items can be temporarily suppressed and later retrieved as chunks, increasing effective capacity w/o increasing simultaneous activity.

🧠 New preprint by Shervani-Tabar, Brincat & @ekmiller on emergent #TravelingWaves in #RNN.

By aligning RNN dynamics to an empirically measured #NeuralManifold, they show that task-relevant TW can emerge through #learning, w/o hard-coding wave dynamics or connectivity. The cool thing here is that the waves are not imposed or engineered, but emerge naturally from learning under #BiologicallyPlausible constraints:

ive heard for a long time that dual n-back exercises can improve working memory and just ran across this study that seems to point to it being particularly effective for people with adhd. i do them on and off (you can find free apps for it) but one thing i notice is that its extremely unpleasant. i wonder if this is just a me thing? its NEVER enjoyable as a task, and usually something i really don't want to do. link to study: https://www.mdpi.com/2076-3425/15/9/998

🧠 New paper by Deistler et al: #JAXLEY: differentiable #simulation for large-scale training of detailed #biophysical #models of #NeuralDynamics.

They present a #differentiable #GPU accelerated #simulator that trains #morphologically detailed biophysical #neuron models with #GradientDescent. JAXLEY fits intracellular #voltage and #calcium data, scales to 1000s of compartments, trains biophys. #RNNs on #WorkingMemory tasks & even solves #MNIST.

"Out of sight, out of mind" is so unfortunste aspect of ADHD because life has so many aspects that can't be kept in sight all the time.

People, projects, tasks, ideas, hobbies, plans, items you shouls buy from grocery store, all go ln the same equal list of "If I can't see it RIGHT NOW, I am physically unable to remember it exists."

It isn't malicious. Or a sign of not caring.
It is brain unable to work neurotypically.

So... I got the results of the psychiatric evaluation I had at Johns Hopkins two weeks ago. It was ordered by my oncologist.

Unsurprisingly, my working memory is crap. The solution: make lists and take notes. This works well for stuff I had to think about ahead of time. However, when I have good ideas in the moment, I tend to forget to record it, and then it is gone. 😩

The rest of my abilities were on target.

This evaluation said nothing about my #autism.

It's funny. The psychiatrist started by pointing out that they compare me with people with the same general background as I have. She said that highly intelligent people are not used to be called "average." I was thinking: "Yes, I get it. You're going to compare me with other Ph.D. of my age, etc. and not with every individual in the US."

I'm also pretty sure that the government is going to say "you can flip burgers" and take me off disability when we get to my renewal.

I can do more than flip burgers, but... :headache:

Very excited that my first paper with Alessandra Souza and Klaus Oberauer is now published in @PNASNews

We investigated the mechanisms underlying repetition learning as a model system for the interaction between #workingMemory and #longTermMemory. By using a Bayesian hierarchical mixture modeling approach to model learning curves on the individual level, we reveal misconceptions in current theories which resulted from aggregating data over individuals.
