    Don't mind me, just cruising around Detroit (via Google Street View).

    This is what's been thrown away: The best deal & highest rebate of 27 nations. No Schengen. No Euro. Full input. Full veto. Seat at the table 759 trade treaties. Full FOM Freedon to travel, live, work & retire freely. Cost? £29/person per year. There will be No coming together

    Today I will be teaching my undergrad course "How to build a brain from scratch" for the 2nd year running. I've put the materials online - include a document with all lecture slides and notes, which is about as long as a decent novel. Enjoy!

    Ok he came home & I showed him the evidence (last crumbs). He says it’s the same thing he used & swears it’s a homemade bath bomb. I say it’s DOUGH. My house is in turmoil. The cats are weeping. WHAT IS IT

    Yesterday, we were blessed by a visit from , none other than the fabulous and awe inspiring Prof Mamokgethi Phakeng, VC of to talk to us about opportunity & resilience, failure & recovery and generally kicking ass. Thank you so much for your time & wisdom!

    In prior work (Doe et al, 2019) has considered the problem of parrot walking, however, the proposed method had severe limitations. The approach presented in this paper is novel and versatile. To our knowledge it is the first work considering multiple parrots simultaneously.

    Week 1 at the ended with a tour around Cape Town for our wandering wondering minds of the imbizo attendees + faculty🧑‍🤝‍🧑. Lots of fun, lots of science 🔬. Always learning, even on a "recharge day" for wk2, which is set to be 🔥 "Seek adventures that open your mind."

    In any case, we hope to provide a framework for the cognitive control of memory, efficient memory search, and its interaction with decision making. The end. Check more work Thanks for flying Neurovogels, we appreciate your business. Please come back soon.

    Obvs there is other work out there, like context-dependent gating in deep learning by Masse and colleagues, . We’re also anxiously waiting for ’s new stuff, and , , (among others) have related work. Stay tuned!

    So, in summary our model shows: (i) how gating and inhibition can contribute to memory, (ii) how memory access/availability dynamically change over time, and (iii) how context representations, such as those observed in hippocampus and PFC, may interact with and control memory.

    And then we also looked at how our model can aid in continual learning, can implement arbitrary and overlapping contexts, and can encode distributions over memory strengths, to enable flexible memory storage and recall. In short, context makes everything better. Check it out!

    That’s the gist of it. But wait, there is more: Context also controls the memory stability of patterns, enabling dynamic control of memory accessibility. We show this, and suggest it may explain some memory disorders in which memories are not forgotten, but become inaccessible.

    It should be said, TaSS is a real pain in the (t)ASS to get ‘right’, so how would neurons do it?

    Both types of contextual control require extra neurons, of course! So we calculate how many extra neurons are needed to encode context for each scheme, & determine if the memory gains we see are “real” and feasible. Check the paper for details, but we still come out on top. Phew!
