Posting poetry has seemed too lightweight - but of course it's not. Anyway, here's something not too heavy - Street Food, after all. By Daniel Halpern, from #Poetry magazine, May 2025 issue.

This is so upsetting. Outsourcing writing does not "free up time to do more science" it's just a step further toward becoming the CSO at the top of a managerial pyramid rather than being a scientist

Feedforward amplification in recurrent networks underlies paradoxical neural coding The activity of single neurons encodes behavioral variables, such as sensory stimuli ([Hubel & Wiesel 1959][1]) and behavioral choice ([Britten et al. 1992][2]; [Guo et al. 2014][3]), but their influence on behavior is often mysterious. We estimated the influence of a unit of neural activity on behavioral choice from recordings in anterior lateral motor cortex (ALM) in mice performing a memory-guided movement task (H. K. [Inagaki et al. 2018][4]). Choice selectivity grew as it flowed through a sequence of directions in activity space. Early directions carried little selectivity but were predicted to have a large behavioral influence, while late directions carried large selectivity and little behavioral influence. Consequently, estimated behavioral influence was only weakly correlated with choice selectivity; a large proportion of neurons selective for one choice were predicted to influence choice in the opposite direction. These results were consistent with models in which recurrent circuits produce feedforward amplification ([Goldman 2009][5]; [Ganguli et al. 2008][6]; [Murphy & Miller 2009][7]) so that small amplitude signals along early directions are amplified to produce low-dimensional choice selectivity along the late directions, and behavior. Targeted photostimulation experiments ([Daie et al. 2021b][8]) revealed that activity along the early directions triggered sequential activity along the later directions and caused predictable behavioral biases. These results demonstrate the existence of an amplifying feedforward dynamical motif in the motor cortex, explain paradoxical responses to perturbation experiments ([Chettih & Harvey 2019][9]; [Daie et al. 2021b][8]; [Russell et al. 2019][10]), and reveal behavioral relevance of small amplitude neural dynamics. ### Competing Interest Statement The authors have declared no competing interest. [1]: #ref-21 [2]: #ref-3 [3]: #ref-19 [4]: #ref-24 [5]: #ref-18 [6]: #ref-15 [7]: #ref-36 [8]: #ref-12 [9]: #ref-7 [10]: #ref-42

Agree that the Svoboda ALM work is the most rigorous stuff on attractor dynamics, but even they now favor a feedforward amplification model - see www.biorxiv.org/content/10.1...

Assuming that's true, is it possible then to reverse engineer the statistics of the data from the learned network state? (I'm thinking of olfaction, where we are nowhere near vision in terms of understanding the data distribution)

Mr. Mamdani’s self-identification as both Black or African American and Asian on his application points to the heterogeneity of his background and upbringing as the child of Indian Ugandan and Indian American parents who brought him up in Uganda, South Africa and New York City.
Mr. Mamdani was born in Kampala, Uganda, to Mira Nair, an acclaimed film director who grew up in India and later emigrated to the United States, and Mahmood Mamdani, then a college professor at Makerere University. Both his parents are of Indian descent, but his father’s family came to East Africa more than 100 years ago, Mr. Mamdani said.
When asked if any of his family had intermarried while in East Africa, he said in the interview on Thursday, β€œThey’re all of Indian origin, from Gujarat.”

Almost beyond belief, but the New York Times appears to be endorsing the Amin-era definition of Africanness.
